I'm getting some linker errors. Thanks for maintaining this!

EDIT: the linking errors (sometimes) go away if you do the build process/makepkg twice.

Added a patch to remove the boost_system requirement, builds again.

build fails for me:

Regards!

If it's linked to an old version of boost... rebuild? 🤨 Don't create symlinks for it.

In requires libboost_program_options.so.1.81.0 currently, but seems to work with libboost_program_options.so.1.83 too when symlinked

If I try compiling this in a chroot, I consistently get the same error as Wild_Penguin, and just rerunning the command has no effect. I was able to get it to compile outside of a chroot by running makepkg twice in a row, only it was libapngasm.so that it couldn't find the first time around. I don't understand what's wrong, either.

.... and right after posting it doesn't fail!

Just a guess: maybe this is some kind of build bug which happens because it tries to link the executable before the library has been linked? Something hardcoded in the Makefile which should not be hardcoded?

Just sometimes linking the library is faster than linking the executable, which means it will not always fail. But because only linking the executable has failed, on subsequent runs the library is there -> it succeeds.

I should probably mention I now next to nothing on the internals of Makefiles.

This always fails on the first try of building:

However, re-running makepkg right after succeeds:

And it looks like the package is build correctly and works.

Possibly something fishy in the Makefile. Don't have time to investigate myself right now why it fails.

I do not. Please file a bug report or elaborate.

I'm having the same issue as @lubosz
