Bugzilla Bug 131402

gtkwave fails to compile on my system; no (explicit) errors are reported by
emerge.

The only error that is visible (after grepping through the emerge output) is
this:
ar: libz.a: Malformed archive

But this is well before the emake fails.

emerge output to follow.

emerge output

emerge output, straight from screen.

command: emerge geda-suite

Arg.. I merged it with MAKEOPTS=-j1 and it compiled file.

Perhaps this should be added into the ebuild (after further testing)?

I've never seen this error,
though mine is gcc-4.1 + glibc-2.4-r2 on ~ppc userland.
And I've emerged it with MAKEOPTS=-j2.
Of cource, gtkwave-1.3.72 was compiled/works fine here.

And then, IIRC, /usr/lib/libz.a comes from sys-libs/zlib.
If libz.a is really makformed, zlib sounds fishy, IMHO.

From the make output, it is created by this line:
ar cq libz.a adler32.o compress.o crc32.o deflate.o gzio.o infback.o inffast.o
inflate.o inftrees.o trees.o uncompr.o zutil.o

The problem was, it is created 7 times (due to MAKEOPTS=-j7).

Perhaps this is an amd64 specific problem?  Or my make version?

a) gtkwave doesn't use system zlib.
b) Problem is because -j6 or other crazy levels try to parallelize more than 
gtkwave's Makefile can handle. I've now set it to use -j2 which works fine in
the ebuild.

Thanks for reporting the bug.
