<![CDATA[Errors occur when Building Qt5.15.2 from sources]]>I just get stuck while trying to build Qt from sources on Ubuntu18.04. any solution? I checked their official doc , and I don't think I miss any step.

I just enlarge RAM up to 32GB, and everything works fine . Thanks everybody.

I'll try it on a real PC later and let you know the result.

Well it would be nice to be able to see what caused unable to execute command: Killed, can you really not discover that?

clang++: error: unable to execute command: Killed
clang++: error: clang frontend command failed due to signal (use -v to see invocation)

Above what I post I can only find these by searching "error".
