ERROR: libass >= 0.11.0 not found using pkg-config
Hello. I am trying to compile ffmpeg with libass included for windows in ubuntu container (docker). But I get an error when running the configure file. To check, I placed the following command in the test_pkg_config() method of the configure file. --- echo “Checking package: $pkg_version” pkg-config --exists --print-errors $pkg_version echo “pkg-config exit code: $?” --- And display like this. --- Checking package: libass >= 0.11.0 pkg-config exit code: 0 ERROR: libass >= 0.11.0 not found using pkg-config --- (pkg-config --exists --print-errors I ran “libass >= (0.11.0” but nothing was printed.) I also ran “ls /usr/local/x86_64-w64-mingw32/include/ass" --- ass.h ass_types.h --- and I got the result that found“ass.h”. Here is the command I ran for complie. --- libass git clone -b 0.17.3 https://github.com/libass/libass.git cd libass autoreconf -fiv ./configure --host=x86_64-w64-mingw32 --prefix=/usr/local/x86_64-w64-mingw32 CPPFLAGS="-I/usr/local/x86_64-w64-mingw32/include" LDFLAGS="-L/usr/local/x86_64-w64-mingw32/lib" --disable-shared make make install cd .. --- --- ffmpeg CPPFLAGS="-I/usr/local/x86_64-w64-mingw32/include" \ LDFLAGS="-L/usr/local/x86_64-w64-mingw32/lib" \ ./configure \ --prefix=/usr/local/x86_64-w64-mingw32 \ --cross-prefix=x86_64-w64-mingw32- \ --arch=x86_64 \ --target-os=mingw32 \ --enable-libvorbis \ --enable-libopus \ --enable-libmp3lame \ --enable-libvpx \ --enable-libwebp \ --enable-libass \ --enable-ffprobe \ --disable-ffplay --- Can someone please provide a solution to this problem?

Well, .config.log is needed. Grab a copy of the same and paste it here for review.

Thank you for quick reply. First, I forgot to mention that I have set the following my environment variables, PKG_CONFIG_LIBDIR="/usr/local/x86_64-w64-mingw32/lib/pkgconfig:$PKG_CONFIG_LIBDIR” PKG_CONFIG_PATH="/usr/local/x86_64-w64-mingw32/lib/pkgconfig:$PKG_CONFIG_PATH” The setting you mentioned to put the .pc file in /usr/local/lib/pkgconfig does not work in my environment when I do this, and pkg-config returns 1. I think the error is probably related to the configure file itself.? Second, I forgot to attach the config.log file, Sorry. So, I attached this. Thanks for let me know. Finally, My container envrioment is ubuntu 24.04 x86_64, ffmpeg release 7.1 from github, gcc 13, g++-mingw-w64-x86-64. ありがとう & お休みなさい．

I think this your problem at hand: WARNING: x86_64-w64-mingw32-pkg-config not found, library detection may fail. You should also see it somewhere in the output, but I took this line from your `config.log`. It means ffmpeg cannot run the pkg-config executable it expects to and instead uses `false` which will always give a negative (non-zero) exit status. Best regards, Alexander

Thank you very much for your reply. It seems I was right on that your point. I made the change using --pkg-config and ffmpeg was recognized. I am so embarrassed... Thank you all very much.
