            Bug ID: 101389
           Summary: Parallel build doesn't work
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: modula2
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
  Target Milestone: ---

I initially tried the builds of the devel/modula-2 branch on both Solaris 11
and Linux/x86_64 in parallel mode (-j48/-j64/-j32).  This failed like this

make[5]: *** No rule to make target 'ASCII.lo', needed by 'libm2pim.la'.  Stop.
make[5]: Leaving directory
'/var/gcc/gcc-12.0.0-20210708/11.4-gm2/i386-pc-solaris2.11/libgm2/libm2pim'
make[4]: *** [Makefile:538: all] Error 2

ASCII.mod lives in gcc/m2/gm2-libs, but there's no ASCII.lo anywhere in the
tree
at this time.

Running the build sequentially allows it to continue past this error.

Thanks for the report - I've pushed some fixes to various Makefiles.  I've
tested it using make -j48 and believe it is fixed.

A -j48 build on x86_64-pc-linux-gnu worked ok yesterday.  However, on
i386-pc-solaris2.11 I ran into exactly the same issue again (i.e. affecting the
build of ASCII.lo).

I managed to complete the build sequentially afterwards, but it's still
strange.
Investigation was hampered by the libgm2 Makefiles not being self-contained.
I'll file a separate PR for that.

I've pushed some changes to gcc/m2/Makefile.in on Tue Jan 11 19:21:06 2022
+0000
which fix parallel build errors on stage1 binaries (exposed when -j48 was
used).  I've rebuilt gm2 using -j48 and -j64 and all regression test pass on
x86_64 debian gnu/linux.  Curious to know if it still fails on ASCII.lo on
Solaris 11.

I just tried again and got the same error on Solaris 11.4/x86 with -j48,
while Linux/x86_64 with -j64 was fine.  Afterwards I found the culprit
(I think): initially I'd been using make 4.2.92 (don't ask).  After I
replaced that by 4.3, the build error went away.

Btw., could you please have a look at the patch in Comment 4 of PR
modula2/101391?  It is necessary to fix about 2000+ testsuite failures
per multilib on both Solaris and Linux, making m2 testing very hard.

Thanks.

I've fixed the PR modula2/101391 (comment 4) and applied changes to getopt
(also added extra testsuite tests to check that this links cleanly).  I'm going
to close this PR as I believe these issues are resolved now.
