With gcc 6 the wrapper isn't necessary anymore. You can disable it
with "--disable-gcc-wrapper". Other configure-flags that we probably
want are "--enable-shared" "--enable-static".

Next step is getting a toolchain setup. Maybe you can take inspiration
from this PR here =)

Thank you for the hint.  I’ll add “--disable-gcc-wrapper” and push to
master.  We can add other configure flags once it becomes apparent that
they are needed.

Thank you, Vincent, for the contribution!

One more thing: I also updated the license.  Musl is released under
Expat.  Pushed to master as ce728f70e5ef8783a28652e382c2c9f61c7b4c06.

Official site pages:

http://www.etalabs.net/compare_libcs.html
http://www.musl-libc.org/intro.html

both says MIT, as does :

$ head -1 COPYRIGHT
musl as a whole is licensed under the following standard MIT license:

$ grep -ri expat *

So where do you found this expat license reference ?
I'm curious, as it looks like I wouldn't have been able to found that myself...

this is what wikipedia has to say about it:

Because MIT has used many licenses for software, the Free Software

to the "Expat License" (used for Expat) or to the "X11 License" (also
called "MIT/X Consortium License"; used for the X Window System by the
MIT X Consortium). The "MIT License" published by the Open Source

Correct.  I looked at the actual license in the COPYRIGHT file and it
looked like Expat, not like X11.  (In Guix we don’t use the name “MIT”,
because it is ambiguous.)  I added a comment to point at the COPYRIGHT
file for details of the third-party pieces under non-copyleft licenses.

Re: [PACKAGE] musl libc

[David Craven]

Vincent, can you run file and readelf -d on the sinit binary you
compiled using the gcc-musl wrapper? That will tell us if it worked.

The output of readelf -d should look like this:

0x0000000000000001 (NEEDED)             Shared library: [libc.so]
0x000000000000001d (RUNPATH)           Library runpath:
[/nix/store/16c974l1kqra3cr475gcgy2gsii45liq-musl-1.1.14/lib]

and the output of file should look like this:

The default sinit build process uses -static, so I get:

$ l /gnu/store/zfbhkbcfjpmnarsid9wl0q4ssswps96p-sinit-1.0/bin/sinit
-r-xr-xr-x 2 root root 9.3K Jan  1  1970

/gnu/store/zfbhkbcfjpmnarsid9wl0q4ssswps96p-sinit-1.0/bin/sinit: ELF

stripped

$ readelf -d /gnu/store/zfbhkbcfjpmnarsid9wl0q4ssswps96p-sinit-1.0/bin/sinit
There is no dynamic section in this file.

And I think that shows it worked, just the static way...

Do you prefer dynamically linked ?

Usually we link stuff dynamically unless there is a reason to do

[-- Attachment #1: Type: text/plain, Size: 482 bytes --]

Hello,

Please, have a look at the attached musl libc packaging.

It may be of use for having smaller statically linked binaries
of selected packages.

Advise about how to finish the submission process, in which
scm file should this go ? I did it standalone, but it looks like
that's not the way things go in guix. Should it go with glibc ?

I'll post a sinit packaging that show how musl can be used.
The sinit package is a minimalistic /sbin/init replacement.

It can go standalone, I don't see any fitting file at the moment.
'base.scm' maybe, but I would just create gnu/packages/musl.scm and add
the file in 'gnu/local.mk'.

It’s fine to put it in a separate file “gnu/packages/musl.scm” and add
it to the list of modules in “gnu/local.mk”.

What follows is a short review with some comments.

I would change it to just “Small C standard library”.  What do you
think?

How about this instead?

    “musl is a simple and lightweight C standard library.  It strives to
     be correct in the sense of standards-conformance and safety.”

“fast” is a bit of a loaded term, so we often avoid it.  Since all
packages in Guix are “free” we usually drop this term from descriptions.

This looks good.  If you agree, I’ll copy the changes and make a commit
with you as the author.

Normally, contributors send changes as patches to the mailing list.  For
future contributions it might be helpful to take a look at the
“Contributing” section in the manual:

    https://www.gnu.org/software/guix/manual/html_node/Contributing.html

This essentially describes how to get started with Guix from a git
clone, generate patches with “git format-patch” and how to send them via
email.  If anything in there is confusing to you please let us know and
we’ll try to help.  You’re also welcome to visit the #guix IRC channel
on Freenode for discussions or questions.

Welcome on board!

Re: [PACKAGE] musl libc

I just built musl and found that it also installs “bin/musl-gcc”, a

Is this something that needs to work in order for this package to be
useful?

Maybe not, but the default / documented way it is to be used is with
the wrapper, so it is nice to have...

Is this not the same with glibc, but in a more hidden way ?

We usually don’t use the “gcc” package directly in Guix.  Instead we use
“gcc-toolchain”, which also comes with a wrapper around the linker that
ensures that binaries are linked with libraries in the store, ensuring
that things generally just work™.

I think more work would be needed to ensure that packages can actually
successfully be linked with musl, but I’m not at all familiar with this.
I had mixed success with a GCC ARM cross-compiler toolchain linking with
newlib, so I know that it’s not exactly obvious how to do this right,
but I find it hard to understand this.

Have you tried building something that links with the libc provided by
this musl package instead of the GNU libc?  I’m not opposed to adding
the package, but I’d like it to be usable.

Is this package in a state where I can review sinit with it? It would be
good if someone can comment on sinit too, as I commented on musl in
general there too.

I'm not sure...

I built musl, made the sinit package use the musl-wrapper as CC,
and it worked (it builds => it works) but couldn't test that sinit as
replacement for pid 1...

I was wondering what happened to musl? Are there any problems left,
anything the people you have been working with can help you to solve? I
had the impression it was almost ready.

Depends on what you consider ready. It's ready for creating a gcc6
musl toolchain... If you want to use it for guixsd you'll also need to
patch ~every package in the base system, since many packages do #ifdef
GLIBC_2.23 #elifdef GLIBC_2.24 etc... that doesn't work well with
musl.

That's not what's needed to get the package itself into the tree.... I
know the obstacles one has with musl, from Gentoo. So if it builds, and
at least one package compiles with it, that's enough to be honest. There
will be one hell of a roadtrip if you intend to fix EVERYTHING for
musl to be satisfied enough to get it into master.

I assume you didn't search for define-public musl in the guix source
tree? It's in gnu/packages/musl.scm

ha! okay, i think I had a very old branch when I searched... thanks for
clearing that up.
