FFmpeg 1.2.1 building fails
30 juin 2013, par Khaled DiabI tried to build ffmpeg 1.2.1 on Ubuntu 13.04 from sources following this guide : https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide
But with adding —enable-shared to ffmpeg configure command :
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
--prefix="$HOME/ffmpeg_build" \
--extra-cflags="-I$HOME/ffmpeg_build/include -fPIC" \
--extra-ldflags="-L$HOME/ffmpeg_build/lib -fPIC" \
--bindir="$HOME/bin" \
--extra-libs="-ldl" \
--enable-shared --disable-static \
--enable-pp --enable-pthreads --enable-gpl --enable-libass --enable-libfdk-aac --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-nonfree --enable-x11grabBut I got this error while compilation :
/usr/bin/ld: libavutil/lls.o: relocation R_X86_64_PC32 against undefined symbol `memset@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC
Any clues on how to solve this error ?
Thanks

Unable to build ; undefined symbols for architecture x86_64 :
30 août 2021, par swittIn the process of trying to create an RTSP screen streaming server, I tried looking at CocoaSplit for an example.



Problem is, I can't get it to compile.



I have FFMpeg installed on my computer using Homebrew following FFMpeg's guide on https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX .



But on compilation, Xcode is throwing out errors such as



Undefined symbols for architecture x86_64:

"_cmnMemAlloc", referenced from:_aac_encode_init in libavcodec.a(libvo-aacenc.o)
"_cmnMemCheck", referenced from:_aac_encode_init in libavcodec.a(libvo-aacenc.o)
"_cmnMemCopy", referenced from:_aac_encode_init in libavcodec.a(libvo-aacenc.o)
"_cmnMemFree", referenced from:_aac_encode_init in libavcodec.a(libvo-aacenc.o)
"_cmnMemSet", referenced from:_aac_encode_init in libavcodec.a(libvo-aacenc.o)




and so on.



The header search paths field in project settings has the directory of
/usr/local/include
in it.


What seems to be the problem here ?
