[FFmpeg-devel] mingw compile problems latest trunk

[Gonzalo Garramuño]

I updated and I'm trying to recompile ffmpeg under mingw32.  I removed 
all references to all the av* libraries in /usr/local/bin and 
/usr/local/lib.

libavutil and libavcodec compiled fine, but I got some linking errors 
when linking avformat.

The problem appears to be the wrong order of -lavutil, which is listed 
before -lavcodec, instead of after.


gcc -shared -Wl,--output-def,avformat-52.def 
-Wl,--enable-runtime-pseudo-reloc -Wl,--enable-auto-image-base 
-L/usr/local/lib -Wl,--warn-common 
-Wl,-rpath-link,"/z/code/PD/libraries/ffmpeg-trunk"/libavcodec 
-Wl,-rpath-link,"/z/code/PD/libraries/ffmpeg-trunk"/libavformat 
-Wl,-rpath-link,"/z/code/PD/libraries/ffmpeg-trunk"/libavutil 
-Wl,-Bsymbolic -o avformat-52.dll allformats.o .... (snip) ... 
-L"/z/code/PD/libraries/ffmpeg-trunk"/libavutil -lavutil 
-L"/z/code/PD/libraries/ffmpeg-trunk"/libavcodec -lavcodec -lz -lm 
-lvorbisenc -lvorbis -logg  -lws2_32

z:/code/PD/libraries/ffmpeg-trunk/libavcodec/libavcodec.a(cscd.o): In 
function `decode_frame':
z:/code/PD/libraries/ffmpeg-trunk/libavcodec/cscd.c:161: undefined 
reference to `lzo1x_decode'
(and many others)
