[NaveenPrasathManikandan]

When I do "bitbake mozjs", i get errors in do_compile only for first time in clean build.

Please find the attached logfile for complete error.

logs say
arm-poky-linux-gnueabi-g++: fatal error: Killed signal terminated program cc1plus

which means you do not have sufficient RAM on build machine and compiler is being killed by the system. Please add more memory to it or reduce build parallelism.

Hi,
Thanks for the reply.Compiled successfully after reducing parallel threads.

@kraj Thanks. I'd been trying to figure out why mozjs was failing for me as well, building on Ubuntu 20.04 in a VM, and this helped resolve the compilation issue. The virtual machine needs at least 8 GB RAM, and I also limited the thread count to 1 less than the VM had via these changes in conf/local.conf

BB_NUMBER_THREADS = "3"
PARALLEL_MAKE = "-j 3"

@NaveenPrasathManikandan You should probably close this issue if you consider it resolved, but I'm posting the details here from my testing for anyone (like me) stumbing across this searching for an explanation.
