On the other hand, ninja associated to meson makes a powerful build system combination, which is expected to be used more and more often.

By default this is the number of cores on the system plus two. In some cases this can overheat a CPU or run a system out of memory. If run from the command line, passing a -jN parameter will limit the number of parallel processes, but some packages embed the execution of ninja and do not pass a -j parameter. Using the optional procedure below allows a user to limit the number of parallel processes via an environment variable, NINJAJOBS. For example, setting: export NINJAJOBS=4 will limit ninja to four parallel processes. If desired, add the capability to use the environment variable NINJAJOBS by running: sed -i '/int Guess/a \ int j = 0;\ char* jobs = getenv( "NINJAJOBS" );\ if ( jobs != NULL ) j = atoi( jobs );\ if ( j > 0 ) return j;\ ' src/ninja.cc Build Ninja with: python3 configure.py --bootstrap The meaning of the build option: --bootstrap This parameter forces ninja to rebuild itself for the current system. To test the results, issue: ./ninja ninja_test ./ninja_test --gtest_filter=-SubprocessTest.SetWithLots Install the package: install -vm755 ninja /usr/bin/ install -vDm644 misc/bash-completion /usr/share/bash-completion/completions/ninja install -vDm644 misc/zsh-completion /usr/share/zsh/site-functions/_ninja Contents of Ninja Installed programs ninja Short Descriptions ninja is the Ninja build system ninja
