Hello, building libavg on my G4 PowerBook running OSX (plus Fink) was not exactly straightforward (euphemism!) but it eventually worked out. I'm posting here some notes of mine that may be useful to other people.
I had to patch the sources (see below), which is why I'm posting this to libavg-devel as well. Cheers, Ciro 1. OS and toolchain =================== Mac OS X 10.4.10 powerpc, build 8R218 Xcode 2.4.1 gcc/g++ gcc version 4.0.1 (Apple Computer, Inc. build 5367) fink 0.8.1.rsync powerpc (default /sw prefix) autoconf 2.60-4 automake1.8 1.8.5-4 libtool14 1.5.22-1000 libtool14-shlibs 1.5.22-1000 2. libavg dependencies (fink packages) ====================================== boost-jam 3.1.13-1 boost1.33 1.33.1-1008 boost1.33-shlibs 1.33.1-1008 ffmpeg 0.4.9-pre1-1012 ffmpeg-dev 0.4.9-pre1-1012 libavcodec1-dev 0.4.9-pre1-1012 libavcodec1-shlibs 0.4.9-pre1-1012 libavformat1-dev 0.4.9-pre1-1012 libavformat1-shlibs 0.4.9-pre1-1012 imagemagick10-dev 6.2.8-1002 imagemagick10-shlibs 6.2.8-1002 sdl 1.2.11-1 sdl-shlibs 1.2.11-1 libxml2 2.6.26-1001 libxml2-bin 2.6.26-1001 libxml2-shlibs 2.6.26-1001 freetype219 2.2.1-4 freetype219-shlibs 2.2.1-4 pango1-xft2 1.10.1-1001 pango1-xft2-dev 1.10.1-1001 pango1-xft2-shlibs 1.10.1-1001 python25 2.5-2 python25-shlibs 2.5-2 3. libavg sources ================= libavg SVN trunk, revision 2241 svn co https://www.libavg.de/svn/trunk/[EMAIL PROTECTED] in order to build the library, revision 2241 has to be patched to fix a few issues (see bottom of this message): patch -p0 < ~/libavg_2241.patch (libavg_2241.patch is attached to this message) 4. Shell environment ==================== Assuming that the shell is bash, we set up the following environment: export CXXFLAGS=-I/sw/include export LDFLAGS=-L/sw/lib export BOOST_ROOT=/sw/include/boost export BOOST_THREAD_LIB=boost_thread export FFMPEG_CFLAGS=-I/sw/include/ffmpeg export FFMPEG_LIBS="-L/sw/lib -lavcodec -lavformat" export PYTHON=python2.5 export PYTHONPATH=/usr/local/lib/python2.5/site-packages 5. Building libavg ================== ./bootstrap ./configure --with-apple-opengl-framework make sudo make install 6. Test cases ============= cd src/test python2.5 Test.py most test cases pass. The following fail: FAIL: testVideo (__main__.PlayerTestCase) FAIL: testVideoSeek (__main__.PlayerTestCase) FAIL: testVideoEOF (__main__.PlayerTestCase) see attached log (test_results.txt) for more information and - possibly - for help. ;-) ============================================================================== PATCH AGAINST libavg sources, SVN trunk, revision 2241 (also attached as libavg_2241.patch): Index: src/video/FFMpegDemuxer.cpp =================================================================== --- src/video/FFMpegDemuxer.cpp (revision 2241) +++ src/video/FFMpegDemuxer.cpp (working copy) @@ -110,7 +110,7 @@ for (it=m_PacketLists.begin(); it != m_PacketLists.end(); ++it) { int CurStreamIndex = it->first; AVStream * pStream = m_pFormatContext->streams[CurStreamIndex]; - avcodec_flush_buffers(pStream->codec); + avcodec_flush_buffers(&pStream->codec); } } Index: src/video/AsyncDemuxer.h =================================================================== --- src/video/AsyncDemuxer.h (revision 2241) +++ src/video/AsyncDemuxer.h (working copy) @@ -22,6 +22,8 @@ #ifndef _AsyncDemuxer_H_ #define _AsyncDemuxer_H_ +#include <math.h> + #include "IDemuxer.h" #include "VideoDemuxerThread.h" Index: src/video/VideoDemuxerThread.h =================================================================== --- src/video/VideoDemuxerThread.h (revision 2241) +++ src/video/VideoDemuxerThread.h (working copy) @@ -22,6 +22,8 @@ #ifndef _VideoDemuxerThread_H_ #define _VideoDemuxerThread_H_ +#include <math.h> + #include "FFMpegDemuxer.h" #include "PacketVideoMsg.h" Index: bootstrap =================================================================== --- bootstrap (revision 2241) +++ bootstrap (working copy) @@ -5,11 +5,11 @@ then # This uses locally-installed libtoolize and automake since the apple-supplied one is buggy # as of OS X 10.4.7 - ../bin/libtoolize --copy --force - ../bin/aclocal -I m4 + libtoolize --copy --force + aclocal -I m4 # Patch that fixes 'local relocation entries in non-writable section' linker error. patch < aclocal.m4.patch - ../bin/automake --foreign --add-missing --copy + automake --foreign --add-missing --copy autoconf else libtoolize --copy --force
