Building the GCC manuals

Building the GCC manuals

[Benoît Thébaudeau]

Hi Yann, all,

I get random build issues for Linaro GCC if using parallel jobs, probably
because of some broken dependencies. It often fails at gcc.sh:795:
"CT_DoExecLog ALL make ${JOBSFLAGS} pdf html".

I was wondering: Why do you use ${JOBSFLAGS} here, but not on line 449:
"CT_DoExecLog ALL make pdf html"?

Best regards,
Benoît

Because I did not review the patch properly enough before I applied it? ;-)
  hg log -pvr 6c5658b8b588

Note the comment about not building in parallel for glibc, too.

Indeed, I remember a case where the manuals did not build, but as I did not
care about manuals at that time, I switched them off to continue debugging
what I was doing at the time, and did not check again later.

If disabling parallel jobs helps build the manuals, then by all means lets
disable parallel jobs when building manuals.

Regards,
Yann E. MORIN.

FWIW, I'm seeing the same issue and the fix proposed
by Benoît fixes it for me, too.

OK, I'll push a fix that disables // jobs when building the manuals.
Thanks for the feedback!
