Subject: [PATCH v3 1/1] kbuild: deb-pkg: Build parallely with current dpkg-buildpackage
Date: Wed, 15 Mar 2023 18:35:24 +0100 [thread overview]
Message-ID: <20230315173524.63179-2-bage@linutronix.de> (raw)
In-Reply-To: <20230315173524.63179-1-bage@linutronix.de>
With dpkg-buildpackage v1.21.10 or later, the only way to build the
deb-pkg generated package parallely is adding -j<N> to the MAKEFLAGS
environment variable or using the --jobs-force option, see dpkg commit
1d0ea9b2ba3f ("dpkg-buildpackage: Change -j, --jobs semantics to
non-force mode"). The package ignores the usual parallel build option
that is described in Debian Policy.
Derive make's -j parameter from the DEB_BUILD_OPTIONS environment variable
that ends up being set by dpkg-buildpackage -j<N>. The snippet is copied
from Debian Policy.
