Description

In times of multi-core machines it is not too uncommon to compile projects like QGIS with "make -j9" or even higher. This does not work, however, as the compile process bails out. Not a big thing, lowering it to -j6 makes it work, but the error shows a build dependency problem in the makefiles that should be fixed.

Here is a part of the log:

History

#1 Updated by sharpie - about 14 years ago

The 1.5.0 source won't build with anything above -j1 for me. Makes development work a bit tedious as it takes a good 5 minutes to compile or recompile.

#2 Updated by Anne Ghisla almost 14 years ago

I regularly compile with make -j4 on my dual core, since a long time, both on Debian and Fedora. Does this bug affect Gentoo only?

#3 Updated by Volker Fröhlich almost 14 years ago

No, not specific to Gentoo. I've seen it happen with -j 16.

#4 Updated by Volker Fröhlich over 13 years ago

  • Assignee deleted (nobody -)

The problem seems gone with version 1.7. I took multiple runs with up to 30 workers.

Can somebody confirm that?

#5 Updated by Volker Fröhlich about 13 years ago

  • Pull Request or Patch supplied set to No
  • Status changed from Open to Closed

As I mentioned before, I haven't seen that happen for quite some time with a high number of workers. Please re-open if I'm wrong.
