Thank you for the new release @CNOCTAVE . The latest tarballs have all permissions set so that I can read and delete those files as user. The installation works without problem.

@Schamschula Does it work for you and macports as well now?

[Schamschula]

The permissions problem for the src/configure file persists. I had to keep the workaround in place.

This version octave_zstd.tar.gz is repacked on ubuntu-latest, see https://github.com/CNOCTAVE/octave_zstd/actions/runs/11815805892/job/32917752120 , where @Schamschula you can see the permission add command.
I develop octave_zstd on WSL,

1. Git or WSL will automatically wipe +x permission even other guys helped me adding it.
2. When manually +x on the file on WSL, the file in the tarred tarball won't contain +x permission.

So don't take the release source(.tar.gz), use my repacked octave_zstd.tar.gz instead.
