Thanks for the quick reply!

Oh right, thanks. That's an excellent reference.

Yes, I've given it the same flags I gave it when I've build it at first.

No! I was hoping I could avoid that as that's extremely CPU intensive..
Is there a way to run make with only the relevant targets? That could be
very helpful...

Plus, do I have to run make after every change to a package definition!?
Will it compile everything from the ground up after every such change? I
wish these technical details would have been documented...

I'm running make while I'm writing this email and I must say that not
only it takes a lot of time and uses a lot of CPU power, it handles way
too much irrelevant things such as translations.

I also noticed it runs GUILEC - is it really necessary? I'm no Guile
expert and I wish I could avoid diving to the whole ecosystem of it just
because I want to use Guix and contribute some packages!

I talked about this subject in a different thread: The design choice of
putting all package definitions in the same repository as the package
manager it self is very uncommon in the Linux. I understand that almost
all of Guix is written in Guile so it must be linked somehow to the
package definitions but I think it makes it very hard to actually
contribute something to the packages definitions! It seems that we,
package maintainers, or to put it simply - the community, need to be too
much involved in the source code of everything in order to help the
distributions. That's rather unfortunate IMHO. I'd like to be convinced
I'm wrong at least in this subject because as I dive more and more into
Guix I feel there have been made a lot of poor design choices in it..

No, I've added new definitions to existing files.

I see, makes sense.

Oh right, makes sense in accordance to your previous comment on running

Oh right. When I'll actually understand everything hopefully with your
guidance, I hope I'll find the time to send some patches.
