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．
