[gentoo-musl] plan9port build fails on multiple levels.

[gentoo-musl] plan9port build fails on multiple levels.

[Rendov Norra]

It fails at building its thread library, it fails at building
lib9/dirread, and I'm not sure if this is related at all but egrep
segfaults and kills the build.

I should also note that this is on ARM

I have patches to fix the first two issues (or at least they compile),
but they're very hacky as I'm not an experienced coder.

Do share them. plan9port doesn't compile on amd64 either.

You'll need to open a bug report outlining all the problems.  However, I
have to say, I don't think I have the time to really address plan9port
on musl, let along on arm.  Is there a good reason why this is useful to
people?  I ask because it really is a matter of the squeaky wheel gets
oiled first.

Excellent, ignore my last message.  If you open a bug report at
bugs.gentoo.org, describe the problem and upload the patches and I'll
put it on the tree.  I also maintain plan9port so I can fix it directly.

Having said that, I'm curious why people are interested in plan9port?

I've attached the patches here, but I hesitate to present them as a
solution since I'm incapable of testing them because of the segfaults
I'm experiencing with egrep.

I'll also note that the version
(e78ed7a67bbaa37dc57dfb37219f505c48755e14) is 3 years old. One big fix
that happened since then is the change of some files' extensions for
.C to .c, since they don't compile as .C .

As for why I'm interested in p9p, it's a feasible replacement base
system in place of GNU--being small but still functional--, and sam
and acme are useful editors.

I don't understand patch 2.  It eliminated an entire function which is
exposed for arm, so I don't see how that can be right.  Can you talk to
upstream about these.

[Rendov Norra]

I thought the functions commented out in the second patch are provided
by musl, but on further inspection, they are only declared in
ucontext.h, but are not implemented.
