core-updates!

core-updates!

[Ludovic Courtès]

Hello!

Here’s a kind invitation for you to look at ‘core-updates’ and make sure
your favorite packages build there.  :-)

  https://hydra.gnu.org/jobset/gnu/core-updates

It seems that the bigger issues have been fixed, so now it will be
mostly leaf packages and/or mips64el/arm needing love.

python-pycairo in core-updates (Re: core-updates!)

[宋文武]

Hi, python-wrapper has a broken `python3-config', which
output cflags to the wrapper instead of the origin python3,
leading the build failure of python-pycairo.


It was introduced in commit 478e75b53.  Does it really needed?

Unless someone suggests a different solution very soon, I would suggest
to revert the commit.

Mozjs is failing, which breaks GNOME:

Hi,

So it appears to resolve the CFLAGS it returns relative to its own
argv[0] or /proc/self/exe, right?

Eventually we should fix this and reinstate this commit, but reverting
it was the right thing in the short term.

Thank you!

[PATCH] gnu: wrap-python3: Use a bash wrapper for 'python3-config'. (was: python-pycairo in core-updates)

The revert isn't in 'core-updates', python-pycairo is broken again for
the same reason.

I can confirm that python-pycairo builds with this patch applied to
core-updates.
