NormCap version - v0.2.3
OS - macOS Catalina

Thanks for reporting this, @1lgatto.

The issue is clearly related to the packaging for MacOS: liblept.5.dylib is a dependency for NormCap that get's shipped with the prebuild-package, but libpng16.16.dylib another dependency for that dependency is not included.

I wonder, if you just have a different version of libpng installed, or if it is missing completely. Would you please run the following command and post its output?

ls /usr/local/opt/libpng/lib/

If it's just a different version, I'll try to link against that, too. Otherwise I'd have to include this libpng into the pre-build package.

ls: /usr/local/opt/libpng/lib/: No such file or directory

Otherwise I'd have to include this libpng into the pre-build package.

Definitely.

ls /usr/local/opt/libpng/lib/

On a clean MacOS installation, /usr/local(or libpng in this case) does not exist as far as I know.

Yes please, my brew is installed in a different location.

Thanks for the infos, @1lgatto and @GrpeApple . I'll try to include libpng into the next package.

(Some background: Theoretically, all dependencies should be discovered by the packaging tool briefcase, but it doesn't find them all. I do my best to add the necessary ones manually, but it's a cumbersome process. I also don't own a Mac, which makes things harder to test for me.)

All dependencies related problems on MacOS now should be fixed with #140, which I published right now as NormCap v.0.2.6.

Feel free to reopen, in case you still have this issue :-)
