Bug 532656 – dev-qt/qtcore-4.8.5-r2 ignores MAKEOPTS="-j8 -l4"

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description codifies 2014-12-15 18:59:19 UTC]

when emerging it only uses 1 core

Reproducible: Always

Steps to Reproduce:
1. emerge dev-qt/qtcore
2. note long compile time
3. wish it was using all cores and over in much less time
Actual Results:  
compiles only on one core

Expected Results:  
should compile on multiple cores

possibly not a bug as it does compile however it would significantly enhance install / update experience if fixed

[Comment 1 Jeroen Roovers (RETIRED) 2014-12-15 19:29:27 UTC]

Another side effect of the multibuild-*.eclass changes?

[Comment 2 Jeroen Roovers (RETIRED) 2014-12-15 19:30:47 UTC]

1) Please post your `emerge --info' output in a comment.
2) Please attach the entire build log to this bug report.

Read the error message that emerge spits out, the full path is written there...

[Comment 6 Davide Pesavento (RETIRED) 2014-12-18 14:51:38 UTC]

Parallel building works for me (I always use -j8 on my dev machine so I'd have noticed if it was broken). The reporter didn't provide a build log so it's impossible to know what might be going on. Closing.

[Comment 7 codifies 2014-12-18 14:56:54 UTC]

please see

[Comment 8 codifies 2014-12-18 14:57:43 UTC]

There was no error message an no path to read

[Comment 9 Davide Pesavento (RETIRED) 2014-12-18 15:13:35 UTC]

Set PORT_LOGDIR=/var/log/portage (or whatever you want) in your make.conf, and the build log will be created there once you re-emerge qtcore. You might also be interested in FEATURES="clean-logs compress-build-logs split-log", see make.conf(5) man page.
