[wolf943134497]

Hi @margaritaG Thanks for your great works!
I have a strange problem, when I run catkin build -j12, the package can not build success! The build process hang long time! the runtime is 7 hours 42 minutes and 50.9 seconds total. no error log In process.

17 of 24 packages succeeded.

any suggestion?
Thanks!

@wolf943134497 it could be that compilation of pcl_catkin (namely, its pcl_ros package) it running low on RAM, see here.

How many CPU cores does your machine have? Try limiting the number of parallel jobs via the -j flag to something that is way lower that your total number of cores.

@margaritaG Thank you for your feedback!
my machine have 16 cores. I try to use 4,6,8,12 parallel jobs,but the problem still can not be solved! I have the same problem when I use pcl_catkin in other project.

@wolf943134497 Did you try catkin build mask_rcnn_ros depth_segmentation gsm_node -j1 -l1?
