Hi Gottfried,

There is no package definition for gtkhash. Guix unfortunately cannot just take any tarball and build it. The good news is that writing a package definition (and optionally adding it to Guix) can be straight forward. This is the build system file: https://github.com/tristanheaven/gtkhash/blob/master/meson.build There we see that it needs a bunch of things (like nettle, blake2, zlib, mbedtls, openssl, etc) for which we should have packages. Packaging it may be a little tricky because of the many dependencies, but it looks doable. We could do this together if you want. Another thing I felt the need to clarify: Guix has thousands of packages that are not GNU packages. I think you meant that there is no package definition for gtkhash in gnu/packages/*.scm, which is correct. -- Ricardo
