Seriously: I hope you are not discouraged by that. And I hope you do it
again and again. Including the errs. Guix is tough stuff and we all
did and do our mistakes. And each one helps to understand the system a
bit better.

And I really like this community because it is so soft and helpful
and polite :-)

I can't speak for Ricardo but only for me: There is some
intrinsic knowledge about each build system and each programming
language, how they generate things, and how this relates to "building
your software really from source in a FSF-compliant way".

Just look at how others have done it in their package definitions.
Present your package definition and get it reviewed. People will hint
you politeful to this knowledge.

Before submitting a patch, try to build it at least twice. If you have
trouble to build it, submit it anyway and tell why it doesn't build
(twice, because of reproducibility).

Take a look at the Manual at

https://www.gnu.org/software/guix/manual/guix.html#Packaging-Guidelines

and


https://www.gnu.org/software/guix/manual/guix.html#Submitting-Patches

The latter one is like a checklist to go through before submitting.

Happy Guix-ing,

Björn
