New to Code::Blocks, to work on an open-source project.
I specified "Number of processes for parallel builds" to be 12 (this is a 6-core cpu). Still my cpu monitor indicates little use of processor and a rebuild takes over 9 minutes. Adding -pthread in "Other compiler options" and "Other linker options" does not make any difference. I include a sample build output below.
Rebuilding from command-line with cmake takes 3 minutes and cpu monitor indicates 100% use. With QTCreator a rebuild takes 4 minutes and cpu monitor also indicates 100% use.
Any suggestions?
This is 17.12 on Archlinux 5.0.4-arch1-1-ARCH #1 SMP PREEMPT.
