Thank you for the pointers. Package is up to date after a brief test.

v3.5.2 supports using the C++23 standard <format> and <print> headers in place of the fmt library. These C++23 headers now ship with GCC starting in version 14. This will result in a more stable build, as the fmt library is having frequent ABI breaks.

If you wish to proceed with the GCC libraries, you should modify the PKGBUILD as follows: 1. Add -DUSE_STD_FORMAT=ON to the CMake arguments 2. Drop fmt from the depends array.

The solution might be to forgo the "new" lib dependencies and use ffmpeg proper instead, but it might not solve the need to rebuild on each ffmpeg updates.

error: failed to prepare transaction (could not satisfy dependencies)
:: installing ffmpeg (2:7.0.1-1) breaks dependency 'libavcodec.so=60-64' required by rsgain

Uninstalling and then reinstalling rsgain resolved these errors on my system.

My bad, my CFLAGS was borked in my makepkg conf. rsgain builds perfectly well now.

I get the same results without ccache as well:

ccache is the culprit. you might need to review your build environment or dig up peculiarities between cmake + ccache.

Build fails with the following error:

Could someone point out where the issue lies?

I think you forgot to bump pkgrel in your PKGBUILD. People won't see the new package since they already have rsgain-3.5-1 installed
