F.3.4 Speeding up compilation

The makefile supports compiling in parallel. For this, you can use the -j N make option, to start N processes.

For the packages and utils, the compilation is governed by fpmake, and make just starts fpmake.

The fpmake process can also compile in parallel, but this needs a separate option -T N. You need to specify this option in the FPMAKEOPT variable:

make all -j 7 FPMAKEOPT=’-T 7’

The last step of a normal compilation cycle is recompiling the compiler with whole program optimization. This can be turned off:

make cycle NOWPOCYCLE=1
