SAMUFLAGS is recently added to the samurai build tool, an implementation of the ninja build format (which is a competitor to Makefiles). Currently, samurai implements support for -v (verbose) and -j (configuring the number of parallel jobs) and rejects all other SAMUFLAGS. Adding SAMUFLAGS support to makepkg will allow users to configure how many jobs to use when building packages, which is an important consideration as the ninja build format is becoming fairly popular these days; meson uses it exclusively, cmake can optionally output it, and it can often speed up the time a build takes. Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> --- Support for SAMUFLAGS is only in git master. See https://github.com/michaelforney/samurai/pull/21 for discussion about its implementation. Submitting patch now for bikeshed purposes, but it "should" be safe to pull in as there will hopefully be a new samurai release in a week or two, and I expect this patch will take longer to review anyway, and even longer for pacman 5.2 :p Note: this overlaps with the RUSTFLAGS patch, and therefore depends on it. In the unlikely event that this patch gets accepted *first*, I can rebase it... doc/makepkg.conf.5.asciidoc | 9 +++++++-- etc/makepkg.conf.in | 1 + scripts/libmakepkg/buildenv.sh.in | 2 +- scripts/libmakepkg/buildenv/makeflags.sh.in | 2 +- 4 files changed, 10 insertions(+), 4 deletions(-) diff --git a/doc/makepkg.conf.5.asciidoc b/doc/makepkg.conf.5.asciidoc index 3f37190d..27e1162e 100644 --- a/doc/makepkg.conf.5.asciidoc +++ b/doc/makepkg.conf.5.asciidoc @@ -82,8 +82,13 @@ Options available linker flags. **MAKEFLAGS=**"makeflags":: - This is often used to set the number of jobs used; for example, `-j2`. - Other flags that make accepts can also be passed. + This is often used to set the number of jobs used in a Makefile; for + example, `-j2`.
