could not load libgtk-3.0.dylib

[whitebm2024]

On a m2 mac air it compiles fine but this is the error it gives when ran

dlopen(libgtk-3.0.dylib, 0x0002): tried: 'libgtk-3.0.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibgtk-3.0.dylib' (no such file), '/usr/lib/libgtk-3.0.dylib' (no such file, not in dyld cache), 'libgtk-3.0.dylib' (no such file), '/usr/local/lib/libgtk-3.0.dylib' (no such file), '/usr/lib/libgtk-3.0.dylib' (no such file, not in dyld cache) could not load: libgtk-3.0.dylib

I've tried a bunch of things including brew install gtk+3 and putting it in an app bundle and other things mentioned in #63 but it still does not work. A similar thing also happens with nimx so I'm not sure what the problem is.

I have no knowledge about macOS, but maybe you could search for the files on your system and compare the file names. Maybe it's a higher Gtk version or another reason for a different file name.

I realized when running the file command on the dylib and on NiCalc executable that their architectures were arm64 and x86_64 respectively and I'm pretty sure that's no good so I tried to compile with the --cpu:arm option and it gives me this nice error which seems to be saying the nim and c compiler disagree on the size of a pointer. I have no idea how to fix something like this.

Oh yes, the M2 is an Arm CPU. I think you should look for information how to compile Nim code for this CPU in general, not related to NiGui or Gtk. I don't have any device with Arm CPU to test.
