Aria2 shell script and batch file

I wrote a BASH shell script and a DOS batch file that can be used to download files using aria2 — Aria2 is a command-line tool for downloading files. The script and the batch file take 2 arguments; the first one is for the bittorrent hash in 40-digit hexadecimal number and the second one is for arbitrary one-word description.

• aria2.bat
  
• aria2.sh
  

aria2.bat can be used on Windows, and aria2.sh can be used on Linux and *BSD. Make sure that aria2c is in PATH. For example, if you want to download an ISO file for the OpenSUSE DVD, you would type something like:

aria2.bat 198472f5217d843cceb1a4c82233f009ed6608af opensuse-dvd-586

To find the value of a bittorrent hash (that long hex number), you can cut it from a magnet link you find on a Web site — Magnet links allow you to download actual files without first having to download bittorrent files (*.torrent). When you see a magnet sign, right-click on it to display the shortcut menu and select Copy Link Location.

Then, paste it somewhere, for example, inside the URL address bar. The hash value comes after the btih: string.

After you find the bittorrent hash, use it as the first argument to the script and make up anything for the second argument, as shown in the example above.

Bittorrent Info Hash Values for Windows 8 ISO

Windows 8 ISO files have the following BTIH hash values. Use them with my aria2 script to download Windows 8.

1. en_windows_8_x86_dvd_915417.iso
   
   C5D92B32277685436DEDE9957B80083D26062C03
   
2. en_windows_8_x64_dvd_915440.iso

To Compile ndiswrapper 1.58rc1 for Linux 3.5.4

ndiswrapper allows Linux users to use Windows drivers for PCI/USB network adapters on Linux. If you own a network device for which Linux support is still absent or premature, then you need to compile ndiswrapper yourself and install Windows driver for your network device. Fortunately, today's Linux supports most network devices out-of-box, so most distributions don't bother to include ndiswrapper. However, I am compiling ndiswrapper believing that Windows NDIS drivers would outperform native Linux drivers.

To my surprise, building the latest version of ndiswrapper (1.58rc1) did not require any patch. After compiling Linux 3.5.4, I downloaded the ndiswrapper source from the sourceforge site. I chose the testing version because I thought it would work better with Linux 3.5.x. I unpacked the source.

tar xzvf ndiswrapper-1.58rc1.tar.gz
cd ndiswrapper-1.58rc1

I typed the following commands to compile and install ndiswrapper.

KVERS=3.5.4 make uninstall
KVERS=3.5.4 make
KVERS=3.5.4 make install

Then, I generated modules.* files again.

depmod -e -m -F /boot/System.map-3.5.4 3.5.4

The following files were installed by ndiswrapper.

/lib/modules/3.5.4/misc/ndiswrapper.ko
/sbin/loadndisdriver
/usr/sbin/ndiswrapper
/usr/sbin/ndiswrapper-buginfo
/usr/share/man/man8/loadndisdriver.8
/usr/share/man/man8/ndiswrapper.8

To Build Transmission-Daemon for Windows

Transmission is a free bittorrent application available on Linux. It is a pretty neat tool compared to other bittorrent software. It is possible to compile and use Transmission on Windows, thanks to Cygwin. First, install Cygwin using the Cygwin installer(setup.exe). I set the Root directory to C:\Cygwin and chose to install the following packages in addition to base packages.

• bison
  
• gettext-devel
  
• libtool
  
• make
  
• binutils
  
• gcc4-g++
  
• patch
  
• pkg-config
  

Compile zlib.

./configure --prefix=/usr --static
make
cp -iv zconf.h zlib.h /usr/include
cp -iv libz.a /usr/lib

Build OpenSSL.

./Configure -DHAVE_STRUCT_TIMESPEC -lz -lpthread threads zlib --prefix=/usr cygwin
make
make install

Build CURL.

./configure --prefix=/usr --disable-shared --with-ssl --with-ca-bundle=ca-bundle.crt
make
make install

Compile libevent.

./configure --prefix=/usr --disable-shared
make 
make install

Lastly, build transmission.

./configure --prefix=/usr --disable-shared --enable-static --disable-nls --without-gtk CPPFLAGS=-DHAVE_STRUCT_TIMESPEC
make
make install

If you get snprintf error with libutp, insert the following line into utp.cpp:

extern int snprintf(char *, size_t, const char *, ...);

To Compile UnionFS-fuse 0.26 on Debian Linux

I am trying to switch to unionfs-fuse for my live CD, but so far I haven't much success yet. Debian's unionfs-fuse package in Sid is outdated (version 0.24), so I compiled version 0.26. I had to install libfuse-dev in order to be able to build UnionFS-fuse. I probably needed cmake too, but I didn't choose to install cmake.

• cmake
  
• gcc
  
• libfuse-dev
  
• make
  

I edited Makefile to change PREFIX.

PREFIX=/usr
BINDIR=/bin
SBINDIR=/sbin

I just typed make to begin compilation.

make
make install

The following files are installed.

/usr/bin/unionfs
/usr/sbin/mount.unionfs
/usr/share/man/man8/unionfs-fuse.8

To make it compatible with Debian and derivatives, I renamed unionfs.

mv /usr/bin/unionfs /usr/bin/unionfs-fuse

Compile Aria2 1.15.2 with MinGW

Aria2 is a command-line download utility. It can be used to download files quickly from http(s), ftp, bittorrent, magnet and metalink locations. I prefer this handy tool over other programs, such as Free Download Manager and Frostwire because it's lean, fast and full of features. It took me a couple of days to compile Aria2 with all the features available. The following step-by-step guide will help you build your own aria2 program (aria2c.exe) the way I did.

1. Install MinGW
   

   Follow one of the following guides to install MingW:

   
   
   • Setting up MinGW64 with Cygwin
     
   • Installing MinGW on Windows
   
   
   
2. POSIX Threads
   

   Download the source for Pthreads library (pthreads-w32-2-9-1-release.tar.gz) and compile it like this:

   
   

   make clean GC-static
   cp pthread.h semaphore.h sched.h /mingw/include/
   cp libpthreadGC2.a /mingw/lib/libpthread.a

   
   
   
3. zlib
   

   Zlib is needed by the OpenSSL library below. Download the zlib source and compile it like this:

   
   

   make -f win32/Makefile.gcc
   make -f win32/Makefile.gcc install BINARY_PATH=/mingw/bin INCLUDE_PATH=/mingw/include LIBRARY_PATH=/mingw/lib

   
   
   
4. OpenSSL
   

   Aria2 requires either GnuTLS or OpenSSL for secure transfers. In this guide, OpenSSL is chosen over GnuTLS. Use 7-zip to unpack the tarball because it contains symbolic links.

   
   

   ./Configure -DHAVE_STRUCT_TIMESPEC -DPTW32_STATIC_LIB -L/mingw/lib -lz -lpthread -lws2_32 --prefix=/mingw threads zlib mingw
   make
   make install

   
   
   

5. Expat

   
   

   Aria2 can use either LibXML2 or Expat for XML parsing. In this guide, Expat will be used. Download the expat source and compile expat like this:

   
   

   ./configure --build=i686-w64-mingw32 --prefix=/mingw --disable-shared --enable-static
   make 
   make install

   
   
   

6. C-Ares

   
   

   C-Ares is a C library that performs DNS requests and resolves DNS names asynchronously. Download the C-ares source from c-ares.haxx.se and unpack it. Then, compile C-Ares as follows:

   
   

   ./configure --build=i686-w64-mingw32 --prefix=/mingw --disable-shared CPPFLAGS='-I/mingw/include -DCARES_STATICLIB'
   make
   make install

   
   
   

7. SQLite 3

   
   

   Download the SQLite source (sqlite-amalgamation-3071300.zip) and build SQLite 3:

   
   

   gcc -O2 -DNDEBUG=1 -DTHREADSAFE=1 -c *.c
   ar ru /mingw/lib/libsqlite3.a sqlite3.o
   cp -iv *.h /mingw/include

   
   

   Create sqlite3.pc and put it in /mingw/lib/pkgconfig.

   
   

   prefix=/mingw
   exec_prefix=${prefix}
   libdir=${exec_prefix}/lib
   includedir=${prefix}/include
   
   Name: SQLite
   Description: SQL database engine
   Version: 3.5
   
   Libs: -L${libdir} -lsqlite3
   Cflags: -I${includedir}

   
   
   

8. aria2c

   
   

   Finally, we are ready to compile Aria2. Download the Aria2 source from aria2.sf.net and unpack the source. Then, configure aria2 as follows:

   
   

   ./configure --build=i686-w64-mingw32 --prefix=/mingw --enable-threads=posix --with-ca-bundle=ca-bundle.crt --disable-nls LIBS='-lpthread -lws2_32 -lcares -lz' CPPFLAGS='-DPTW32_STATIC_LIB -DCARES_STATICLIB'
   

   
   
   
   
   

   Then, issue the following commands to compile Aria2:

   
   

   make
   make install

   
   
   
9. Optionally, strip and compress the executable aria2c.exe.
   
   

   strip aria2c.exe
   upx --best --strip-relocs=0 aria2c.exe

   
   

To download my Windows builds of aria2, go here.

Aria2c Usage

aria2c --file-allocation=prealloc ftp://192.168.1.64/pardus.iso

If aria2 aborts a download due to a connection error, you can resume the download any time using aria2c like this:

aria2c -c ftp://192.168.1.64/pardus.iso

To download files from URL's written in a file urls.txt to a folder Downloads, run aria2 as follows. The urls.txt should contain one download per line with URL's seperated by a tab:

aria2c -i urls.txt -d Downloads

Setting up MinGW64 with Cygwin

This is just another version of my previous post on Cygwin with focus on MinGW64. I hope this guide will more or less make it easy to install MinGW on Windows. After following this guide, you'll be ready to develop genuine Windows applications. Just download and run setup.exe from the Cygwin website and choose the following packages.

• bison
  
• gettext-devel
  
• libtool
  
• make
  
• mingw64-i686-gcc-g++
  
• mingw64-x86_64-gcc-g++
  
• patch
  
• pkg-config
  

To select a package for installation, type the name of the package in the Search box, expand the category by clicking the + sign, and click on the package until its version number shows up.

When you see the Resolving Dependencies window, just accept and click Next.

Mounting /mingw

If you're building 32-bit applications, add the following line to /etc/fstab so that /mingw is properly set up.

/usr/i686-w64-mingw32/sys-root/mingw /mingw none bind

If you're building 64-bit applications, add the following line to /etc/fstab instead.

/usr/x86_64-w64-mingw32/sys-root/mingw /mingw none bind

Creating Symbolic Links

Start the Cygwin terminal and create symbolic links to gcc and g++ in this manner.

ln -s /usr/bin/i686-w64-mingw32-gcc.exe /usr/i686-w64-mingw32/bin/gcc.exe
ln -s /usr/bin/i686-w64-mingw32-g++.exe /usr/i686-w64-mingw32/bin/g++.exe
ln -s /usr/bin/x86_64-w64-mingw32-gcc.exe /usr/x86_64-w64-mingw32/bin/gcc.exe
ln -s /usr/bin/x86_64-w64-mingw32-g++.exe /usr/x86_64-w64-mingw32/bin/g++.exe

Setting up environment variables

If you're building 32-bit applications, type the following commands or put them in ~/.profile:

export CC=/usr/bin/i686-w64-mingw32-gcc.exe
export CFLAGS="-mtune=pentium2 -mthreads -mms-bitfields -O2"
export CXXFLAGS="-mtune=pentium2 -mthreads -mms-bitfields -O2"
export CPPFLAGS="-I/mingw/include"
export LDFLAGS="-L/mingw/lib -Wl,--enable-auto-image-base -Wl,--enable-auto-import -Wl,--enable-runtime-pseudo-reloc"
export PATH=/mingw/bin:/usr/i686-w64-mingw32/bin:/usr/local/bin:/usr/bin
export PKG_CONFIG_PATH=/mingw/lib/pkgconfig

If you're building 64-bit applications, type the following or put in ~/.profile:

export CC=/usr/bin/x86_64-w64-mingw32-gcc.exe
export CFLAGS="-mtune=core2 -mthreads -mms-bitfields -O2"
export CXXFLAGS="-mtune=core2 -mthreads -mms-bitfields -O2"
export CPPFLAGS="-I/mingw/include"
export LDFLAGS="-L/mingw/lib -Wl,--enable-auto-image-base -Wl,--enable-auto-import -Wl,--enable-runtime-pseudo-reloc"
export PATH=/mingw/bin:/usr/x86_64-w64-mingw32/bin:/usr/local/bin:/usr/bin
export PKG_CONFIG_PATH=/mingw/lib/pkgconfig

How to Compile libssh2 for Windows with MinGW

libssh2 is a client-side C library implementing the SSH2 protocol, according to the definition on libssh2.org. I am compiling libssh2 because it enables me to build applications for transferring files securely between Unix/Linux sites and Windows machines. Although there seems to be a way to build libssh2 with Visual Studio, this post focuses on using MinGW. If you haven't set up MinGW yet, just follow one of these posts on how to install MinGW.

• To install MinGW from mingw.org
  
• To set up Cygwin with MinGW toolchain
  

First, I compiled zlib. I downloaded zlib source code from zlib.net, unpack the tarball, and typed the following commands:

make -f win32/Makefile.gcc
make install -f win32/Makefile.gcc BINARY_PATH=/mingw/bin INCLUDE_PATH=/mingw/include LIBRARY_PATH=/mingw/lib

Then, I compiled OpenSSL as shown in this post. For your information, libgcrypt can be used instead of OpenSSL (See this post). I typed the following commands to build OpenSSL.

./Configure -DHAVE_STRUCT_TIMESPEC -L/mingw/lib -lz -lws2_32 --prefix=/mingw zlib mingw
make
make install

I downloaded the latest libssh2 tarball from libssh2.org and unpacked it. I typed the configure as follows:

./configure --prefix=/mingw --with-libz --with-openssl --disable-examples-build

Then, I typed make.

make
make install

Somehow, only the static library was generated, but that's okay. I think that's because openssl was only compiled statically.

Compile xz for Windows using MinGW

xz is the new popular compression format. To build xz tools and libraries, I issued the following commands.

./configure --prefix=/mingw --disable-shared --disable-nls --disable-lzma-links --disable-scripts
make
make install

I got the following files:

lzmadec.exe
lzmainfo.exe
unxz.exe
xz.exe
xzcat.exe
xzdec.exe

Note that xz can be used to create and decompress lzma files also.

Compile libcddb for Windows

libcddb is used to query for information about audio Compact Discs that has been loaded in media players and CD rippers. Compiling libcddb is not so hard with MinGW.

1. First, I installed MinGW. I compiled zlib and libiconv.

   
   
   

2. Then, I compiled libcdio. I downloaded the latest development source from its git web server.

   
   

   ./autogen.sh
   ./configure --prefix=/mingw
   make 
   make install

   
   
   

3. I compiled libcddb like this:

   
   

   ./configure --prefix=/mingw
   make
   make install

   
   
   

FLAC for Windows

FLAC, short for Free Lossless Audio Codec, is an audio format similar to MP3, but lossless. Thus, audio compressed in FLAC has no loss in quality. With digital storage getting cheaper everyday, it makes sense to copy or preserve sound in the near-perfect quality. I'm compiling FLAC with MinGW because it's needed by some programs I want to build.

1. I installed MinGW, of course. I also instaled NASM because it was suggested during configure. I just downloaded yasm-1.2.0-win32.exe and renamed it as nasm.exe.





2. I think it's not necessary, but I compiled zlib and libiconv.

   
   
   

3. I built OGG.

   
   

   ./configure --prefix=/mingw
   make
   make install

   
   
   

4. Then, I built FLAC.

   
   

   ./configure --prefix=/mingw --enable-sse

   
   
   

   The --enable-sse option is for SSE-capable CPU's which mean nearly all new desktop CPU's today. I began make.

   
   
   

   make

   
   
   

   I got errors about SIZE_T_MAX. To fix it, I just changed the line 38 in flac-1.2.1/include/share/alloc.h

   
   
   

   # if defined _MSC_VER || defined __MINGW32__

   
   
   

   I got another error compiling examples/cpp/encode/file/main.cpp. To fix it, I inserted the following line after <stdlib.h> on line 33.

   
   
   

   #include <string.h>

   
   
   

   I got no more error. I installed flac.

   
   
   

   make install

   
   
   

Compile libRTMP with MinGW

The libRTMP library provides online multimedia streaming support for many open-source projects, such as ffmpeg and curl. I am building librtmp for use with ffmpeg and mplayer. I downloaded the latest release tarball from here.

1. First, I compiled zlib as shown in this post.

   
   

   make -f win32/Makefile.gcc
   cp -iv zlib1.dll /mingw/bin
   cp -iv zconf.h zlib.h /mingw/include
   cp -iv libz.a /mingw/lib
   cp -iv libz.dll.a /mingw/lib

   
   
   

2. Then, I built OpenSSL as shown in this post.

   
   

   ./Configure -DHAVE_STRUCT_TIMESPEC -L/mingw/lib -lz -lpthreadGC2 -lws2_32 --prefix=/mingw threads zlib mingw
   make
   make install

   
   
   

3. Then, I built librtmp.

   
   

   make SYS=mingw
   cp -iv *.exe /mingw/bin

   
   

   To build the shared library, I typed:

   
   

   cd librtmp
   gcc -shared -o librtmp.dll -Wl,--out-implib,librtmp.dll.a rtmp.o log.o amf.o hashswf.o parseurl.o -lssl -lcrypto -lz -lws2_32 -lwinmm -lgdi32

   
   

   To install librtmp, I typed the following:

   
   

   cp -iv librtmp.dll /mingw/bin
   cp -iv amf.h http.h log.h rtmp.h /mingw/include/librtmp
   cp -iv librtmp*.a /mingw/lib
   cp -iv librtmp.pc /mingw/lib/pkgconfig

   
   
   

4. Sometimes, librtmp.pc fails to be generated. In that case, make it yourself and copy it to /mingw/lib/pkgconfig.

   
   
   

   prefix=/mingw
   exec_prefix=${prefix}
   libdir=${exec_prefix}/lib
   incdir=${prefix}/include/librtmp
   
   Name: librtmp
   Description: RTMP implementation
   Version: 2.3
   Requires: openssl libcrypto
   URL: http://rtmpdump.mplayerhq.hu
   Libs: -L${libdir} -lrtmp -lz
   Libs.private: -lws2_32 -lwinmm -lgdi32 -lssl -lcrypto
   Cflags: -I${incdir}

   
   
   

Build OpenSSL with MinGW

OpenSSL is an open-source library that provides cryptographic and network security functions. It is used by so many open-source software that require SSL/TLS support. To build OpenSSL for Windows, first install MinGW. There are two flavors of MinGW: mingw and mingw64. Just pick one of the following and set it up accordingly:

• Installing MinGW on Windows
  
• Setting up MinGW64 with Cygwin
  

Then, download the latest source tarball from the OpenSSL website and unpack it with 7-zip. 7-zip should be used because MinGW/MSYS tar has trouble with tarballs containing symlinks. However, cygwin has no problem with tarballs containing symlinks.

OpenSSL optionally incorporates the following libraries when found.

• zlib
  
• pthreads-win32
  

Assuming that you compiled both zlib and pthread as shown in the above links, configure OpenSSL like this.

./Configure -DHAVE_STRUCT_TIMESPEC -DPTW32_STATIC_LIB -L/mingw/lib -lz -lpthreadGC2 -lws2_32 --prefix=/mingw threads zlib mingw

Then, run make.

make

If you run into errors compiling some test codes, just copy dummytest.c over. However, it doesn't happen under Cygwin.

cp -iv test/dummytest.c test/md2test.c
cp -iv test/dummytest.c test/rc5test.c
cp -iv test/dummytest.c test/jpaketest.c

Then, install OpenSSL.

make install

To Build the Live555 library with MinGW

The Live555 streaming media library is an open-source implementation of RTP/RTCP/RTSP/SIP multimedia streaming protocols. I mainly use it with MPlayer. To compile it with MinGW, download the source for live555 library and extract the tarball under /mingw/lib:

cd /mingw/lib
tar xzvf live555-latest.tar.gz
cd live

compile it like this:

./genMakefiles mingw
make

Live555 and MPlayer

Normally, mplayer will detect the live555 library automatically. If not, append --enable-live to the ./configure command.

After running ./configure, open config.mak in a text editor and make the following changes.

• Append the following text to CXXFLAGS= line.
  

  -I/mingw/lib/live/liveMedia/include -I/mingw/lib/live/UsageEnvironment/include -I/mingw/lib/live/BasicUsageEnvironment/include -I/mingw/lib/live/groupsock/include

  
  
• Append the following text to EXTRALIBS= line.
  

  /mingw/lib/live/liveMedia/libliveMedia.a /mingw/lib/live/UsageEnvironment/libUsageEnvironment.a /mingw/lib/live/BasicUsageEnvironment/libBasicUsageEnvironment.a /mingw/lib/live/groupsock/libgroupsock.a -lstdc++

  
  

Creating a Shared Library for live555

To create a shared library from the static live555 libraries, I ran the following command:

gcc -shared -o livemedia.dll -Wl,--out-implib,liblivemedia.dll.a -Wl,--whole-archive liveMedia/libliveMedia.a UsageEnvironment/libUsageEnvironment.a BasicUsageEnvironment/libBasicUsageEnvironment.a groupsock/libgroupsock.a -Wl,--no-whole-archive -lstdc++ -lws2_32

I got livemedia.dll and liblivemedia.dll.a. I copied these files under MinGW.

cp -iv livemedia.dll /mingw/bin
cp -iv liblivemedia.dll.a /mingw/lib

To use these files, I would define environment variables as follows:

CXXFLAGS='-I/mingw/lib/live/liveMedia/include -I/mingw/lib/live/UsageEnvironment/include -I/mingw/lib/live/BasicUsageEnvironment/include -I/mingw/lib/live/groupsock/include'



LIBS='-lstdc++ /mingw/lib/liblivemedia.dll.a'

Building MPlayer and Mencoder for Windows

MPlayer is one of my favorite media players. It is used with a frontend like smplayer, gnome-mplayer and MPlayerGUI to provide a good alternative to Windows Media Player. Although there are already several Win32 builds of MPlayer on the net, I like to build MPlayer on my own using MinGW compiler because I want to optimize my build for my CPU. So I installed MinGW and compiled MPlayer as follows.

1. Build ffmpeg statically or dynamically as shown in this post.

   
   
   
2. (Optional) Compile the lzo library:
   
   

   ./configure --prefix=/mingw && make && make install

   
   
   

3. (Optional) Fribidi is a rendering library for right-to-left scripts, such as Arabic and Hebrew. If you are a speaker of such right-to-left languages, compile fribidi statically as shown below:

   
   

   ./configure --prefix=/mingw --disable-shared --disable-debug
   make
   make install

   
   

   More information can be found here.

   
   
   
4. Download JPEG source from ijg.org and complie JPEG:
   
   

   ./configure --prefix=/mingw --enable-static
   make
   make install

   
   
   
5. Compile libPNG:
   
   

   ./configure --prefix=/mingw --disable-shared
   make
   make install

   
   
   
6. Compile libiconv, Freetype, expat and fontconfig statically in that order:
   
   

   ./configure --prefix=/mingw --disable-shared
   make install

   
   
   
7. Compile libdca:
   
   

   ./configure --prefix=/mingw
   make
   make install

   
   
   
8. (Optional) Download DirectX headers from any of the following locations and unpack them in /mingw/include:
   
   
   
   
   • http://www.videolan.org/vlc/dx7headers.tgz
     
   • http://www.mplayerhq.hu/MPlayer/contrib/win32/dx7headers.tgz
     
   
   
   
9. Download the latest mplayer source (mplayer-export-snapshot.tar.bz2) and unpack it. (patch 1 and patch 2)
   
   

   tar xjvf mplayer-export-snapshot.tar.bz2
   cd mplayer-export-2010-02-07/

   
   

   Then, run ./configure:

   
   

   CPPFLAGS='-DFRIBIDI_ENTRY="" ' ./configure --prefix=/mingw --enable-runtime-cpudetection --enable-static --enable-theora --enable-fribidi --disable-ffmpeg_a --disable-gl --disable-vidix --yasm=/mingw/bin/yasm --extra-libs='-lfribidi'

   
   

   The CPPFLAGS value allows fribidi to be linked statically.

   
   
   
10. Build Mplayer:
    
    

    make

    
    
    

    After successful build, strip the executables:

    
    

    strip m*.exe

    
    
    

    Optionally, compress the executables with upx:

    
    

    upx --best --strip-relocs=0 mplayer.exe
    upx --best --strip-relocs=0 mencoder.exe

    
    
    

11. Download MPlayer codecs from here. The MPlayer codecs for Windows platform has a filename like windows-essential-20071007.zip. Extract the codecs package and you'll get a folder "windows-essential-20071007". Rename it as "codecs" and move the "codecs" folder inside where mplayer.exe file is located.

    
    
    

12. Make sure that HOME environment variable is set to your personal folder(for example, C:\Users\Jocelyn). Upon the first run of mplayer, a new folder named mplayer will be created in your HOME folder. Copy codecs.conf to the mplayer folder. The "config" file stores default options for playing movie files. Open the "config" file and make changes as follows:

    
    

    # Write your default config options here!
    cdrom-device=D:
    dvd-device=D:
    ao=dsound
    vo=direct3d
    font=C:\WINDOWS\FONTS\MALGUN.TTF
    framedrop=yes
    subcp=cp949

    
    

My win32 build of mplayer can be downloaded from here. It is recommended that the zip archive should be extracted in C:\Program Files.

Running MPlayer

Now, let's try mplayer. First, get a movie file ready. In the Command Prompt, type a command in the following form:

mplayer mymoviefile.avi

Alternatively,

mplayer -vo direct3d -ao win32 -font C:\WINDOWS\FONTS\Tahoma.ttf -framedrop mymoviefile.avi

A new window will pop up with the movie playing inside it.

The next step is to get and set up SMPlayer.

Building cdrkit for Windows

cdrkit is another CD/DVD burning tool that was spun off from the cdrtools project. Some say cdrkit is inferior to cdrtools, but I haven't found a problem with cdrkit yet. Although I prefer cdrtools to cdrkit, I'd like to give cdrkit a try. To build cdrkit with MinGW, I had to compile some libraries first.

1. zlib
   

   First, I compiled zlib:

   
   

   tar xzvf zlib-1.2.7.tar.gz
   cd zlib-1.2.7
   make -f win32/Makefile.gcc
   cp -iv zlib1.dll /mingw/bin
   cp -iv zconf.h zlib.h /mingw/include
   cp -iv libz.a /mingw/lib
   cp -iv libz.dll.a /mingw/lib

   
   
   
2. POSIX threads for Win32
   

   New genisoimage seems to use pthread for making checksums. I compiled pthread like this:

   
   

   make clean GC
   cp -iv pthreadGC2.dll /mingw/bin
   cp -iv pthread.h semaphore.h sched.h /mingw/include/
   cp -iv libpthreadGC2.a /mingw/lib
   cp -iv libpthreadGC2.a /mingw/lib/libpthread.a

   
   
   
3. PCRE
   
   

   Then, I compile PCRE:

   
   
   

   ./configure --prefix=/mingw --enable-pcre16 --enable-unicode-properties
   make
   make install
   cp /mingw/include/pcreposix.h /mingw/include/regex.h
   cp /mingw/lib/libpcreposix.a /mingw/lib/libregex.a
   cp /mingw/lib/libpcreposix.dll.a /mingw/lib/libregex.dll.a

   
   
   
4. libmagic
   
   

   I built the open-source file command. I configured it like this:

   
   
   

   ./configure --prefix=/mingw

   
   
   

   Then, I added the following lines to config.h:

   
   
   

   #define WIN32 1
   #define MAGIC "magic"

   
   
   

   Compile libmagic:

   
   
   

   make && make install

   
   
   

   I got an error trying to build file.exe, so I modified src/Makefile:

   
   

   file_LDADD = libmagic.la /mingw/lib/libpcreposix.dll.a

   
   
   
5. libiconv
   
   

   I built libiconv like this:

   
   

   ./configure --prefix=/mingw
   make
   make install

   
   
   
6. CMake
   
   

   Then, I built CMake.

   
   

   ./bootstrap --prefix=/mingw
   make
   make install

   
   
   
7. cdrkit
   

   I unpacked the cdrkit source and applied the patch that I found at the mailing list. Here are the modified patches of mine.

   
   
   
   • cdrkit-1.1.9-mingw.patch
     
   • cdrkit-1.1.11-mingw.patch
     
   
   
   

   I used the command below to applied the patch.

   
   
   

   patch -p1 -l < ../cdrkit-1.1.9-mingw.patch

   
   
   

   Then, I compiled cdrkit:

   
   
   

   cmake -G "MSYS Makefiles"
   make

   
   

   After successful build, I copied the executable files (*.exe) to my folder.

   
   

Issues and Fixes

1. 
   

   I got an error linking genisoimage. I edited genisoimage/CMakeLists.txt to resolve the issue:

   
   
   

   IF(USE_MAGIC)
    ADD_DEFINITIONS(-DUSE_MAGIC)
    LIST(APPEND EXTRA_LIBS "shlwapi")
    SET(MAGICLIBS magic)
   ENDIF(USE_MAGIC)

   
   
   

2. I got errors compiling sha256.* and sha512.*. I made the following changes.

   
   
   
   • I removed all lines that read #include <endian.h>.
     
   • Assume the target machine is little endian.
     
   • change all occurrences of __THROW to __attribute__ ((__nothrow__)).
   
   
   

3. The code in genisoimage/checksum.c gave me errors linking with pthread-w32. To fix it, I replaced a->thread with (a->thread).p.

   
   
   

4. I found that genisoimage and readom still used /dev/null. I changed it to NUL in genisoimage.c and readom.c.

   
   
   

Download my cdrkit Build

Here's my cdrkit build for Windows.

Building cdrtools under Cygwin

cdrtools is a powerful open-source CD/DVD/BD burning tool. It is used as backend software for free DVD-burning applications, such as Infrarecorder and cdrtfe. To build cdrtools for Windows, install Cygwin as shown in this post. Additionally, I installed the following Cygwin packages.

• bison
  
• gcc4-core
  
• gcc4-g++
  
• gettext-devel
  
• libiconv
  
• libtool
  
• make
  
• patch
  
• pkg-config
  

I set up some environment variables before I started.

export CC=/usr/bin/gcc.exe
export CC_OPT="-O2"
export CFLAGS="-march=pentium2 -mtune=i586 -mthreads -mms-bitfields"
export LDFLAGS="-L/usr/lib -Wl,--enable-auto-image-base -Wl,--enable-auto-import -Wl,--enable-runtime-pseudo-reloc"

Then, I built smake.

cd smake-1.2
make
make INS_BASE=/usr install

Then, I built cdrtools.

smake
smake INS_BASE=/usr install

Using cdrtools

I tested my cdrtools build. To create an ISO file from a folder, I ran mkisofs:

mkisofs -J -R -hide-rr-moved ~/Downloads > dl.iso

To burn an ISO:

cdrecord -scanbus
cdrecord dev=0,0,0 speed=8 driveropts=burnfree dl.iso

To make a copy of a data CD:

readcd dev=0,0,0 f=dl2.iso speed=8 retries=16 -nocorr -noerror

To scan a music CD, I ran cdda2wav:

cdda2wav -scanbus
cdda2wav dev=0,0,0 cddb=1 -cddbp-server=freedb.freedb.org -cddbp-port=8880 -J -N

To rip the second track of the music CD:

cdda2wav dev=0,0,0 cddb=1 track=2 ~/Music/track2.wav

Compiling CMake with MinGW

CMake is a portable build system. CMake can be used to replace the traditional GNU build process, as in:

./configure

make

make install

Compiling CMake is fairly simple. After you install MinGW (as shown in this post), download and unpack the CMake source tarball. Run the following commands in order.

tar xzvf cmake-2.8.9.tar.gz
cd cmake-2.8.9
./bootstrap --prefix=/mingw
make
make install

Using cdrtfe 1.5

cdrtfe is free CD/DVD/BD burning software for Windows. cdrtfe actually use the command-line program cdrtools as its burning engine. I have used cdrtools on Linux to create ISO images and burn or rip CD. I'd like to have cdrtools on Windows also. Fortunately, cdrtfe includes cdrtools Win32 binaries along with the nice-looking GUI application.

To install cdrtfe, I downloaded the cdrtfe zip archive (cdrtfe-1.5.zip) and unpacked the zip archive. Double-clicking on the cdrtfe file will start the cdrtfe program. (Warning: Running the Cygwin terminal and cdrtfe at the same time can cause a problem due to cygwin1.dll incompatibility, so close the Cygwin terminal before starting cdrtfe.)

So far, I have only tried ripping music CD's with cdrtfe. I will add more as I get to know more about cdrtfe.

Ripping Audio CD's

To rip a music CD, click on the DAE tab and click the Options button. Check to make sure the options are okay.

Back to the main window, click Read TOC to update the track list, check the Save tracks to folder, and click Start to begin ripping.

Setting Up Cygwin For C/C++ Software Development on Windows

Cygwin provides a Unix-like environment for Windows users. Cygwin is useful for people who want to learn Unix or popular Linux without having to install Unix or Linux. Cygwin can also be used to port Linux applications to Windows or develop genuine Windows applications. To install Cygwin, download setup.exe from the Cygwin website and run it.

Cygwin Packages for Software Development

In addition to the default packages, select the following packages for common development environment:

• bison
  
• gettext-devel
  
• libtool
  
• make
  
• patch
  
• pkg-config
  

To select a package for installation, type the name of the package in the Search box, expand the categories by clicking a plus, and clicking on the package until its version number shows up.

If you want to develop software applications that depend on cygwin1.dll (which emulates Unix on Windows), install one of the following packages. This is when you want to port Linux applications to Windows with little modification.

• gcc-g++
  
  outdated version 3.4.4
  
• gcc4-g++
  
  GCC 4.x that links applications with cygwin1.dll

If you want to develop pure Windows applications, install one of the following packages.

• mingw-gcc-g++
  
  The original MinGW compiler from mingw.org can't build 64-bit applications.
  
• mingw64-i686-gcc-g++
  
  New MinGW compiler from mingw-w64.sourceforge.net.
  
• mingw64-x86_64-gcc-g++
  
  Install these to develop 64-bit Windows applications.
  

When you see the Resolving Dependencies window, just accept and click Next.

Setting HOME Variable

Setting the environment variable %HOME% is useful for various reasons. First of all, it allows regular users to compile freely in their user folder without requiring access to C:\Cygwin. Secondly, it allows users to save user-specific configuration in their user folder. For example, user configuration files such as .profile, .gtkrc-2.0, .fonts.conf and .pango-aliases can be saved in the folder specified by %HOME%.

Setting Up mingw* compiler for Cygwin

The file C:\Cygwin\etc\fstab is used to set up mount points in Cygwin. If you installed mingw64 packages, open the file C:\Cygwin\etc\fstab in a text editor and append the following line.

/usr/i686-w64-mingw32/sys-root/mingw /mingw none bind

Start the Cygwin terminal and type the following commands to set up Cygwin for Windows compilation.

ln -s /usr/bin/i686-w64-mingw32-g++.exe /usr/i686-w64-mingw32/bin/g++.exe
ln -s /usr/bin/i686-w64-mingw32-gcc.exe /usr/i686-w64-mingw32/bin/gcc.exe

Also, set up some environment variables.

export CFLAGS="-march=pentium2 -mtune=i586 -mthreads -mms-bitfields -O2"
export CXXFLAGS="-march=pentium2 -mtune=i586 -mthreads -mms-bitfields -O2"
export CPPFLAGS="-I/mingw/include"
export LDFLAGS="-L/mingw/lib -Wl,--enable-auto-image-base -Wl,--enable-auto-import -Wl,--enable-runtime-pseudo-reloc"
export PATH=/mingw/bin:/usr/i686-w64-mingw32/bin:/usr/local/bin:/usr/bin
export PKG_CONFIG_PATH=/mingw/lib/pkgconfig

Setting Up gcc* Compiler for Cygwin

If you installed the gcc4 compiler (as opposed to mingw*), set up some environment variables to customize your build environment. I usually type the following commands:

CC="/usr/bin/gcc.exe"
CFLAGS="-march=pentium2 -mtune=i586 -mthreads -mms-bitfields -O2"
CPPFLAGS="-I/usr/include"
CXXFLAGS="-march=pentium2 -mtune=i586 -mthreads -mms-bitfields -O2"
LDFLAGS="-L/usr/lib -Wl,--enable-auto-image-base -Wl,--enable-auto-import -Wl,--enable-runtime-pseudo-reloc"
export CC CFLAGS CPPFLAGS CXXFLAGS LDFLAGS
