Hello.
After compiling libx265 as a "static library" (mingw cross compiling
targeting win64)
$ pkg-config --libs --static x265
-L/home/rdp/new/sandbox/win64_static/build_files/lib -lx265
/usr/lib/gcc/x86_64-w64-mingw32/10-win32/libstdc++.a -lgcc
I get this failure at configure time:
./configure --enable-libx265 --arch=x86_64 --target-os=mingw32
--cross-prefix=x86_64-w64-mingw32- --pkg-config=pkg-config

ERROR: x265 not found using pkg-config

So it seems to be linking it not using the output of pkg-config --libs
--static for linking or something?
Workaround is --extra-libs=-lstdc++ but something seems confusing to me here.
Advice welcome. Or if I should file something let me know, thank you :)

It's passing the pkg-config flags just fine.
The x265 .pc file is just broken and does not state its dependency on
libstdc++.

x265.pc does list libstdc++
$ pkg-config --libs --static x265
-L/home/rdp/new/sandbox/win64_static/build_files/lib -lx265
/usr/lib/gcc/x86_64-w64-mingw32/10-win32/libstdc++.a -lgcc
When I configure ffmpeg I specify ./configure --pkg-config-flags=--static
But it appears to be rearranging the order when configure tries to use it?

Possibly useful info:
$ pkg-config --libs x265

$ pkg-config --libs x265 --static
-L/home/rdp/new/sandbox/win64_static/build_files/lib -lx265

It doesn't seem to be using either of those somehow...though I suppose
if I cared enough I could try and figure it out :)
Cheers, thank you!

I don't think that's a valid way to specify libs by absolute path.
At least configure doesn't think so, it specifically looks for stuff
starting with "-l" and discards the rest. Try adding -l: to the beginning.

There is nothing invalid about that, to my knowledge.

Just adding -l to the beginning does sound invalid though.
You could do -L/usr/lib/gcc/x86_64-w64-mingw32/10-win32/ -lstdc++
But it should work just fine the way it is, I do not think discarding everything not starting with -l is correct.
