Description Markus 2018-05-01 12:28:18 UTC

Created attachment 112344 [details]
output of ps aux | grep msgfmt

With ki18n-5.44 building plasma-workspace takes less then 10min on a AMD 6-core-FX3100MHz CPU. With 5.45 and this commit https://cgit.kde.org/ki18n.git/commit/?id=5a70e96795f1e8529780f49ab30b19fcfab12a11 build takes ages to finish (unsure how long the build takes, after 1h i cancelled the build). I reverted that commit and recompiled 5.45 and everything is fine.

That commit should improve build times but for some packages, at least on my system, build will take much, much longer.

Some other packages affected by that are plasma-desktop and konqueror.

Using make -j6 to build the package. make -j1 does not make any difference.

Any suggestions on how to debug that issue? make VERBOSE=1 does not give any more detailed output except 'make' prints some msgfmt commands which take lots of time to finish.
While the package plasma-workspace compiles i tried the following command on another console:
ps aux | grep -c msgfmt 
Sometimes i get more then 3000 active commands. Might that be the problem? Attached is a logfile of 'ps aux | grep msgfmt' that shows lots of msgfmt commands.
Without the commit above i get about a maximum of 2-3 msgfmt commands at the same time and build finishes much faster.
