Bug 173676 – media-gfx/graphviz-2.12 has a parallel build issue (within ./tclpkg/gv)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Axel Dyks 2007-04-07 17:03:58 UTC]

Unfortunately bug #167484 has been closed without reason,
although a "parallel build issue" occurs in folder "./tclpkg/gv"
which is caused my invalid "mutiple target rules" in the Makefile.
The following rules (given as an example. The "ruby", "java", ...
rules are broken as well)

-- original ------------------------------------------
gv_perl.cpp $(PERL_hdr): gv.i
    $(SWIG) -c++ -perl -o gv_perl.cpp $(srcdir)/gv.i
gv_python.cpp $(PYTHON_hdr): gv.i
    $(SWIG) -c++ -python -o gv_python.cpp $(srcdir)/gv.i
------------------------------------------------------

should be rewritten as

-- modified ------------------------------------------
$(PERL_hdr): gv_perl.cpp
gv_perl.cpp: gv.i
    $(SWIG) -c++ -perl -o gv_perl.cpp $(srcdir)/gv.i
gv_php.cpp $(PHP_hdr): gv.i
    $(SWIG) -c++ -php -o gv_php.cpp $(srcdir)/gv.i
$(PYTHON_hdr): gv_python.cpp
gv_python.cpp: gv.i
    $(SWIG) -c++ -python -o gv_python.cpp $(srcdir)/gv.i
------------------------------------------------------

This not only prevents swig from being run _twice_, but also
prevents swig to overwrite gv_python.cpp, gc_perl.cpp on
the second run when building gv.py, pv.pm which might occur
(-jN) while gv_python.cpp, gc_perl.cpp are already being
compiled.

Actually this should better be fixed upstream and/or I
should have attached a patch for Makefile.am, but maybe
I'll do this later ...
 
Cheers
Axel

Created attachment 115683 [details, diff]
patches "./tclpkg/gv/Makefile.am"

... so that all but the IO and LUA multi-target rules that call "swig"
are split into separate rules which avoids duplicate envocations of
"swig" and parallel build issues.
// Both IO_hdr and LUA_hdr are empty, so there is no need to
// modify those rules

I've forwarded the bug report as well as the patch to upstream's
bug tracking system:

It appears that neither upstream nor media-gfx herd are taking
further steps on this matter ...

... which is a little hard to understand, because according to
Murphy's Law "emerge --update ... world" (or any other command
that pulls in the graphviz ebuild ) will typically fail a few
minutes after leaving it unattended and going to bed.
