@sei-ccohen Try echo ${NCPU:-1} :)
@bama4 I think 8 GB should be enough.

It sounds like you are running out of RAM. Are you compiling more than one file at once?

I am running the script/build.bash file

That should only compile one file at once. I'm not sure what to suggest other than adding more memory to your machine. We've definitely compiled Pharos using less than 4 GB of RAM though...
You could also use our pre-built Docker images: https://hub.docker.com/r/eschwartz/pharos/

Actually, the build.bash script defaults to NCPU=-1, which might result in parallel builds. ROSE in particular has several source files that require approximately 4GB of RAM each to compile, and it will fail in small VMs with limited memory. I also recommend that you allocate more RAM, or be very attentive to your system resources during the build. While a full day seems a little excessive, it's in approximately the right order of magnitude (multiple hours) to build all of the depdendencies. This can be addressed with a faster system and multiple processors, but only if there's sufficient RAM to support parallel builds.

Thank you. How much RAM is sufficient enough?

This was resolved when the RAM was increased to 12 GB
