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

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.
please see https://bugs.gentoo.org/show_bug.cgi?id=532656#c4
There was no error message an no path to read
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.
