Err.... what?

That's also the case for the normal gcc package (for example 4.9.3).

But

$ info gcc

works fine.

I can confirm that this bug still exists.  The man page is broken as described, but info gcc works just fine.

Thanks,

The problem is likely caused by lack of the lack of perl as well as pod2man, as
suggested by gcc's build log:

I'm currently rebuilding with those two inputs added, will send a patch
if it fixes the problem.

I believe the attached patch *should* fix it (simply adds perl as a native
input; pod2man apparently comes with perl itself):

[Message part 3 (text/plain, inline)]

I haven't been able to test it though; when attempting to rebuild gcc, I
get a stack overflow before the build process even starts (seems like a
guix problem -- I'll try to git pull & rebuild):

I believe this would cause gcc-5 to be rebuilt, which would cause a
world rebuild, so for the moment we also need a native-inputs entry for
gcc-5 making sure that nothing changes, ie: that we're only using
texinfo there, preferably with a note that it should be changed in the
future.  Also, you should take a look at gnu/packages/commencement and
make sure that we're not adding perl as a native-input for gcc-boot0 or
for libstdc++, wherever that happens to live (I don't remember off
hand).

I assume it is OK for us to build the man pages for gcc-final (if it
happens) since this is the gcc used for actually building packages, and
I believe the one pulled in for gcc-toolchain.

I think this should go to ‘core-updates’.

More precisely, building man pages for ‘gcc-boot0’ is pointless and
possibly adds Perl on the graph for no good reason.  So if we can
arrange to just have man pages in ‘gcc-final’, we’re good.

Efraim, could you check whether that works for ‘core-updates’?

Thanks,
Ludo’.

I believe this is what is accomplished by the attached patch v3. Thanks
to Efraim for the points raised. It turned out that the stack overflow I
was getting attempting to test the previous version was caused by a
circular dependency that was introduced by gcc-boot0 inheriting
perl. This is now fixed.

I spent the last couple hours rebuilding gcc but it failed due to lack
of space on my side... Retrying now but it'll take a few hours before I
can confirm that it works as intended.

Thank you both!

Patch v3 still doesn't fix the problem. There are now pod2man errors
that prevent correctly generating the man pages:

Apparently GCC < 6 required a patch to its texi2pod.pl script, which had
a syntax problem. The attached patch fixes this last problem. I could
successfully build GCC 5.4.0 by using a derived package for testing
(otherwise it would trigger a world rebuild which was never ending of my
lesser machine).

Here's the patch used to test it:

I could then build gcc-dev and verify that the man pages gcc and cpp
were working correctly in an environment instantiated using:

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix environment --pure --ad-hoc gcc-dev man-db
--8<---------------cut here---------------end--------------->8---

The complete patch is attached; it should be good for core-updates.

Thank you,

Maxim

Efraim pushed the patch as 19d27131968355a1da962e52163df51e0e03aba1 so I
think we’re all set.  Thank you!

The definition of ‘gcc-final’ in (gnu packages commencement) has an
explicit #:allowed-references white list, so we can be sure it won’t
retain a reference to Perl.
