Build fails on Gst-1.0.gir

Application Development Build issues
1

Building on a fresh Mac M1 machine running Sonoma I am getting the following error when building Get-1.0.gir

ld: warning: duplicate -rpath '/opt/homebrew/Cellar/glib/2.80.4/lib' ignored
ld: warning: duplicate -rpath '/opt/homebrew/opt/gettext/lib' ignored
ld: warning: ignoring duplicate libraries: '-lglib-2.0', '-lgmodule-2.0', '-lgobject-2.0', '-lintl'
ERROR: can't resolve libraries to shared libraries: m, dl

The PKG_CONFIG_PATH output by the build script shows -lm -ldl. I am not sure where these are coming from. Anyone have an idea what I should be looking for to fix this?

I blew out my brew installation, and am quite further. It appears my x264 installation is not correct.

X264_API extern const x264_level_t x264_levels[];

Is there a recommended way of install ffmpeg, x264 and friends. I used brew. Additionally I see

../subprojects/gst-libav/ext/libav/gstavprotocol.c:272:28: error: incompatible function pointer types passing 'int (void *, uint8_t *, int)' (aka 'int (void *, unsigned char *, int)') to parameter of type 'int (*)(void *, const uint8_t *, int)' (aka 'int (*)(void *, const unsigned char *, int)') [-Wincompatible-function-pointer-types]

Going back to ffmpeg 6 solved the last two issues above, but the x264 issue remains.

Well back to

....

I think this has something to do with pygobject3.

I got it sorted out.
