Parallel make: set -j8 as the default option
build, gnu-make, linux, makefile, parallel-builds
Solution
Your question is not about threads, but processes (jobs) executed by make.
The simple, way to set this, when make is used from the console is adding:
alias make="/usr/bin/make -j 8"
to your `.profile` file.
You can also use `setenv MAKEFLAGS '-j 8'`, but `MAKEFLAGS` can ignore this parameter in some scenarios, because keeping desired number of processes requires communicating with recursive `make` calls. Happily this method works with current versions of GNU Make.
Problem
I can set number of threads for the build process using `-j` argument. For example, I have 4 cores +4 virtual. When I write: `make -j8` the speed increases 4 times. Is it possible to set that value as default? (For example, in Linux Gentoo, in config file, it's possible to set this default value). p.s. I have Arch Linux
