Hi again,
the attached Makefile patch seems to fix the parallel build problems.
Is there a chance of getting this into trunk? Should I open an issue or send the patch somewhere else?
Cheers, Jonas

See http://bugs.python.org/issue5309 Cool! I'll look into this. The patch there works well for me. I've made one small update, and submitted the new version in the bug tracker. Regarding the other build problem, I might have found some hint: - Parser/pgen.o ends up in both the PARSEROBJS and PGENOBJS variables in the Makefile - PARSEROBJS is depended upon in a few places, hence it could be that make starts to build Parser/pgen.o - PGENOBJS is built when building PGEN, which happens *in a different make that is called recursively* I think the culprit is the rule for GRAMMARH which calls make recursively. Is there a reason that GRAMMARH has to generate PGEN like this? Couldn't it just depend on PGEN? Cheers, Jonas -------------- next part -------------- A non-text attachment was scrubbed...
