Hi Everyone,

It took me about 15 minutes to install GCC on Guix because Guix named
the GCC package libgccjit.

I understand Guix package manager is powerful. I think you should use
an alias feature (or whatever it is called under Guix), and create and
few aliases to help with administration:

gcc -> libgccjit
g++ -> libgccjit
gcc-c++ -> libgccjit

These are the names developers expect for the compiler. They don't
expect a name like libgccjit.

With the aliases in place, a command like 'guix install gcc' works as expected.

Without the aliases (and absent a sane package name), people have to
lookup the documentation and read how to use the package manager for a
simple task like installing the compiler. When 50 or 100 developers
waste 15 minutes of their time, that's about 1 man-week wasted.
There's no reason to waste man-weeks on simple tasks.

Thanks in advance.

Hi,

the GCC package itself isn't to useful. I think you are looking for the
gcc-toolchain package which installs GCC, binutils and libc.

Dear,

Thank you for the feedback.

It is a common "mistake" and there is an entry in the manual about that:


Moreover, I am not sure what you want is 'libgccjit' but 'gcc-toolchain'.

However, you are right. Something is wrong with "guix search", for example:

Toggle snippet (14 lines)
guix search gcc | recsel -p name,relevance | head -11
name: libgccjit
relevance: 11

name: gccmakedep
relevance: 11

name: gccgo
relevance: 11

name: gcc-toolchain
relevance: 11

It is unfortunate and the synopsis of 'libgccjit' should be more
descriptive than "GNU Compiler Collection".

As said above, the right command is "guix install gcc-toolchain".

I understand the frustration. What could be improved in the manual?

How did you process after

$ guix install gcc
guix install: error: gcc: unknown package

? Which terms did you use with "guix search"?


All the best,

I’m sorry to hear it caused you so much trouble and actually led you to
install the “wrong” package.

I’ve now added such an alias:


I’ll install ‘gcc-toolchain’, which is explained here:


Thanks,

Nice use of deprecated-package. :-)

About discoverability (guix search gcc) there is still 2 issues:

1. libgccjit inherits from gcc-9 but the synopsis/description is not updated.
2. gccgo uses custom-gcc and so reuse the same synopsis/description.

The #1 is easy to fix -- I can send a patch which precises the
synopsis/description of libgccjit.

What is the best for #2? Add 2 optional arguments to 'custom-gcc'
(synopsis and description)? Other?


Last, it is unfortunate that the package gccmakedep has the exact same
number of occurence of the term 'gcc' but it is not an issue.

Cheers,
simon

Lol... Yeah, I found out libgccjit was not right either.

I was working from

Sounds good!

custom-gcc returns a package value, so we can inherit from that and
overwrite the synopsis and description fields.

Well, custom-gcc is already an inherit. So it seems awkward to inherit twice.
But yes, since it is the only case, it could be the simplest:
gccgo-4.9 would become only 'define' and a new 'gccgo' would be
inherit from gccgo-4.9 and would be define-public.

Nobody will ever know when just looking at the final package. :)

The patches #43342 http://issues.guix.gnu.org/issue/43342 tries to
fix these 3 items.
