MinGW: Building GPAC

GPAC is an MPEG-4 multimedia transcoder suite. This post documents my attempt to compile GPAC with MinGW for the Win32 platform.

1. Compile OpenSSL as shown in this post.
   
   
2. Build FreeType as shown below.
   

   tar xjvf freetype-2.3.9.tar.bz2
   cd freetype-2.3.9
   ./configure --prefix=/mingw --disable-shared
   make
   make install

   
   
   

3. liba52 AC3 decoder

   
   

   Download the liba52 source from liba52.sf.net and compile libA52 like this:
   

   tar xzvf a52dec-0.7.4.tar.gz
   cd a52dec-0.7.4/
   ./configure --prefix=/mingw
   make
   make install

   
   

   The following files are installed:
   

   bin/a52dec.exe
   bin/extract_a52.exe
   include/a52dec/a52.h
   include/a52dec/attributes.h
   include/a52dec/audio_out.h
   include/a52dec/mm_accel.h
   lib/liba52.a
   lib/liba52.la
   man/man1/a52dec.1
   man/man1/extract_a52.1

   
   
   

4. MAD Library

   
   

   The MAD (MPEG Audio Decoder) library is a fast fixed-point MPEG audio decoder that doesn't require an FPU numeric processor. Download the libmad source from mad.sf.net and compile MAD like this:

   
   

   tar xzvf libmad-0.15.1b.tar.gz
   cd libmad-0.15.1b
   ./configure --prefix=/mingw --disable-shared --enable-fpm=intel --disable-debugging
   make
   make install

   
   

   The following files are installed:
   

   include/mad.h
   lib/libmad.a
   lib/libmad.la

   
   
   
5. Get DirectX headers from either location below and extract it into /mingw/include:
   
   • http://www.videolan.org/vlc/dx7headers.tgz
     
   • http://www.mplayerhq.hu/MPlayer/contrib/win32/dx7headers.tgz
   
   
   
6. Download the source for the JPEG library and compile as follows:
   

   tar xzvf jpegsrc.v7.tar.gz
   cd jpeg-7
   ./configure --prefix=/mingw --enable-static
   make
   make install

   
   
   
7. Download the source for the PNG library and compile like this:
   

   tar xzvf libpng-1.2.38.tar.gz
   cd libpng-1.2.38/
   ./configure --prefix=/mingw --disable-shared
   make
   make install

   
   
   
8. Then, compile GPAC like this:
   

   ./configure --prefix=/mingw --cpu=i586 --strip --use-png=no --use-ffmpeg=no
   
   cp config.h include/gpac/internal

   
   
   

   Before compilation, I edited config.mak:

   
   

   SSL_LIBS=-lssleay32 -leay32 -lgdi32 -lws2_32 -lz

   
   

   Then, I started make:

   
   

   make
   
   make install

   
   
   

   I encountered an error during the final compilation. But I got MP4Box.exe which was all I needed. So I copied mp4box.exe and libgpac.dll from ~/gpac/bin/gcc.
