Description Walt H 2007-01-22 00:54:21 UTC

Just an enhancement request...  Maybe there's a reason for this, but since rev. 1.168 of the kde.eclass, parallel makes are no longer allowed?  With dual core CPU's more common, parallel makes can speed up the compile, particularly the kde-meta modular builds.

Reproducible: Always

Err, care to look up the changes properly before filing a bug next time, please.

The only emake -j1 in that eclass is for calling Makefile.cvs that _cannot_ be ran in parallel.

The main make process is ran without -j1 and works great in parallel.

Comment 2 Walt H 2007-01-26 00:39:08 UTC

It appears you are correct :)  I was building for a new arch in a chroot and it seemed to be taking longer than normal.  I notice that at many times throughout the build, it was only utilizing one core, but maybe that's due to the kdeenablefinal flag?  Anyway, sorry for the false alarm.

Yes, kdeenablefinal will kill the idea of parallel make, as only one file is compiled per directory.
