Cannot build ffmpeg 4.0 with --enable-libvorbis

[Mario Grgic]

I am trying to build ffmpeg 4.0 with Xcode 9.3 on macOS 10.13.4. I have installed latest libvorbis with its dependencies.

I have configured ffmpeg as follows:

./configure --prefix=/Volumes/ramdisk/ffmpeg --as=yasm --extra-version=Wu --disable-shared --enable-static --disable-ffplay --enable-gpl --enable-pthreads --enable-postproc --enable-gray --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-libspeex --enable-bzlib --enable-zlib --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-nonfree --enable-version3 --enable-runtime-cpudetect --enable-libvo-amrwbenc --enable-opengl --enable-opencl --datadir=/usr/local/share/ffmpeg --mandir=/usr/local/share/man

and got the error:

ERROR: vorbis not found using pkg-config

The config.log shows:

If I also add -logg option to the linker command:

gcc -L/Volumes/ramdisk/ffmpeg/lib -Wl,-dynamic,-search_paths_first -I/Volumes/ramdisk/ffmpeg/include -L/Volumes/ramdisk/ffmpeg/lib -o /var/folders/rk/7t49495d3w1btf_fydzx6k200000gn/Tffconf.p6ZBvzlB/test /var/folders/rk/7t49495d3w1btf_fydzx6k200000gn/Tffconf.p6ZBvzlB/test.o -lvorbis -logg

then it all works. I have compiled vorbis with ogg support, and it seems it now needs to have ogg library added as dependency. I have worked around this problem by modifying vorbis.pc file in pkgconfig path to also have -logg in library search path.

[Timo R.]

That means its pkg-config file is broken then. It's supposed to provide such informations.

This is not an ffmpeg issue. It looks like you only have static libraries of libvorbis and libogg in your system, so you need to run ffmpeg's configure with --pkg-config-flags="-static" in order to get pkg-config to explicitly include all of libvorbis dependencies (That means libogg).

Replying to jamrial:

This is not an ffmpeg issue. It looks like you only have static libraries of libvorbis and libogg in your system, so you need to run ffmpeg's configure with --pkg-config-flags="--static" in order to get pkg-config to explicitly include all of libvorbis dependencies (That means libogg).

Thank you. That solves my problem. And yes, I am building static ffmpeg with all dependencies (i.e. all third party libraries built statically as well) for maximal portability.
