[SOLVED] Parallel jobs with dpkg-buildpackage

miguelg · 04-19-2014, 06:37 AM

Attempting to build a deb package with 8 parallel jobs but can only spawn one single job.

I've got the following debian/rules file:

Code:

#!/usr/bin/make -f
export DH_OPTIONS


%:
	dh $@  --with autotools-dev

I tried running:

- dpkg-buildpackage -j8
- setting (and exporting) DEB_BUILD_OPTIONS=parallel=8
- and even setting (and exporting) MAKEFLAGS=-j8

Nothing worked and the build makes use of only one core. What's the correct procedure to spawn a parallel build?

NOTE: source builds using all 8 logical cores if make -j8 is used instead.

Found solution to this and it is as simple as appending --parallel to dh in the debian/rules file. So the rules file becomes:

Code:

#!/usr/bin/make -f
export DH_OPTIONS


%:
	dh $@  --with autotools-dev --parallel

dpkg-buildpackage still needs to be invoked with -j<num_threads> though.
