Hello!

I started looking at what it would take to upgrade glibc to 2.29 on
‘core-updates’.  Bad news: it depends on Python.

I came up with the WIP patch below, but Python eventually fails to build
with:

--8<---------------cut here---------------start------------->8---
In file included from /tmp/guix-build-python-minimal-3.7.3.drv-0/Python-3.7.3/Modules/ossaudiodev.c:37:0:
/gnu/store/q4i9kq2py260y9ysq1qkjjhpgsmbdcbh-glibc-mesboot-2.16.0/include/sys/soundcard.h:1:29: fatal error: linux/soundcard.h: No such file or directory
 #include <linux/soundcard.h>
                             ^
compilation terminated.
--8<---------------cut here---------------end--------------->8---

Maybe we shouldn’t upgrade glibc in this ‘core-updates’ cycle.  We need
this reduced bootstrap merged!

Thoughts?

Also, it would be nice to use ‘python-on-guile’ here, but it doesn’t
provide a ‘python’ executable and I don’t know if it implements enough
to run these scripts.

Thanks,
Ludo’.

I’ll take a look at python-on-guile and see if we can run the scripts
with it.

It's for real:

--8<---------------cut here---------------start------------->8---
Changes to build and runtime requirements:

* Python 3.4 or later is required to build the GNU C Library.
--8<---------------cut here---------------end--------------->8---

https://sourceware.org/ml/libc-announce/2019/msg00000.html

AFAIU the relevant patch is
https://sourceware.org/git/?p=glibc.git;a=commit;h=c6982f7efc1c70fe2d6160a87ee44d871ac85ab0

Before that commit «Python is (was) required to build the GNU C Library
manual and to run some tests.» (and AFAIU tests was skipped if Python
was not available in the build environment)

[...]

Viva Guix! Gio'.

It’s not a June 1st prank, I swear!

Also note that I did try to pass “ac_cv_path_PYTHON_PROG=true” and
variants thereof, but it really really needs Python to generate a few
things.

Yes! ... Although...how are we -- in the far future -- going to replace
Guile with Mes for the Guix bootstrap?  Could it be that the glibc
developers haven't seen my talk? :-/

Maintain a variant of glibc or your own libc?
It's not that far off for an Operating System, and nothing which is impossible.

Since we’re all part of the GNU project our aim should be to make this
work without having to fork the C library.

Maintaining a variant of the C library is not a realistic option,
because it’s enough work to maintain each of the other GNU packages that
are involved in this endeavor.

The python-on-guile package in Guix now provides a “python” executable
that can run simple Python scripts.  I haven’t tested this on the glibc
2.29 scripts yet.

The package propagates these Guile packages, but you’ll need to have
“guile” in your environment.

(It’s on my TODO list to change the wrapper so that the
GUILE_LOAD_{COMPILED_,}PATH is set properly in any case.)
