Presumably part of the solution is the attached patch, but very often
‘make install’ tries to mkdir $(sysconfdir), so a bit of additional work
may be needed.

Can you look into it?

Thanks,
Ludo’.

Thank you for the suggestion!

I'll reinstall Samba from Guix here, and will test it.

I plan to do so this weekend.


Respectfully, Adonay.

Tested the patch today

It seems that, during the `install' phase, something tries to make
"/etc/samba" directory.

The log from the start of the error is attached.

I did `guix build samba` as normal user, and since I'm new to this
situation, I must ask: should I run it as root instead? Or should we
find a way to tell the `install' phase to not make such paths? Or, do
you have other ideas?

That’s a common issue as I mentioned in
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=24834#8> (‘sysconfdir’
corresponds to /etc here.)

Do address it, we need to modify Samba’s build system to not attempt to
create /etc.  Samba uses Waf, so we’d have to comment out the Waf bit
that leads to this attempt to create /etc.  I’m not familiar with Waf so
I’d “grep -r” in the source.  :-)

Could you look into it?

There are similar cases in gnu/packages/*.scm but the fix always depends
on the specifics of the build system being used, so nothing that really
helps here I’m afraid.

Thanks,
Ludo’.

Apply with commit log and indentation tweaks.  It builds fine here.

Thank you!
