Description
Hello,
I can't build ffmpeg shared libraries under Windows with the mpeg dash demuxer enabled.
The problem is always that libxml2 is missing.
I always get the error : " ERROR: libxml-2.0 not found using pkg-config"
Here is what I have done:
I installed msys2
I run cmd from Visual Studio 2015 (Tools > Command prompt) and I run msys2 from there:
C:\msys64>C:\msys64\msys2_shell.cmd -msys
Then, in msys2, I install this:
pacman -S make pacman -S diffutils pacman -S yasm pacman -S mingw-w64-x86_64-gcc pacman -S mingw-w64-i686-gcc pacman -S pkg-config pacman -S mingw-w64-x64-libxml2 pacman -S mingw-w64-x86_64-libxml2 export PATH=$PATH:"C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin" export PKG_CONFIG_PATH=/usr/lib/pkgconfig:/usr/share/pkgconfig:/lib/pkgconfig:/mingw64/lib/pkgconfig/
I go to ffmpeg's folder and I run:
./configure --target-os=win64 --arch=x86_64 --toolchain=msvc --enable-shared --enable-demuxer=dash --enable-libxml2
And I face this error:
ERROR: libxml-2.0 not found using pkg-config If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem.
And yet, I have libxml-2.0.pc in C:\msys64\mingw64\lib\pkgconfig
I don't know if it can help but "pkg-config --libs libxml2" returns:
Package libxml2 was not found in the pkg-config search path. Perhaps you should add the directory containing `libxml2.pc' to the PKG_CONFIG_PATH environment variable No package 'libxml2' found
And "pkg-config --libs libxml-2.0" returns:
-L/mingw64/lib -lxml2 -lz -llzma -liconv -lws2_32
Could someone please save me with a solution?
Thanks in advance
