Ubuntu 18.04 compiles opencv-3.4.16 with the command “make – J” and encounters the error “C + +: internal compiler error: killed (program cc1plus)”. In the system, there are 8 CPUs and 32GB memory, and 83 cc1plus processes are found. Check the help information of make, “- j [n], — jobs [= n] allow n jobs at once; infinite jobs with no arg.”, If there are no parameters, an unlimited number of worker processes are used. The previous command “make – J” can be compiled successfully on a 128GB server.

According to the following commands provided by C + +: internal compiler error, increase the switching space to 8GB. The same problem still exists.

#The size of count is the size of the increased swap space, 1M is the block size, so the space size is bs*count=8192MB
sudo dd if=/dev/zero of=/swapfile bs=1M count=8192 
# format the space into swap format just now
sudo mkswap /swapfile 
chmod 0600 /swapfile  
#Use the swap space you just created
sudo swapon /swapfile

After increasing the size of swap space, the space of KIB swap listed by the top command increases.

Then use the command “make – J 16” to recompile and complete the task successfully.
