Building Synfig using an arbitrary number of cores

FirasH · May 21, 2020, 5:19pm

I was wondering if it would be possible to choose the number of cores used to build.

In the script build.sh:

synfig/synfig/blob/e60a668e53cd718e910ad4172774f2672e797172/autobuild/build.sh#L49


pushd "${REPO_DIR}/.." > /dev/null
REPO_DIR=`pwd`
popd > /dev/null

RELEASE=8
if [ -z "$PREFIX" ]; then
#PREFIX=$HOME/synfig
PREFIX=`pwd`/build
fi

MAKE_THREADS=2					#count of threads for make

# Allow overriding PREFIX and other settings
if [ -f "./build.conf" ] ; then
	. "./build.conf"
fi

if [ -z $DEBUG ]; then
	export DEBUG=0
fi

In practice, can we add an option to set the value of MAKE_THREADS?
(if not already available)

https://synfig-docs-dev.readthedocs.io/en/latest/common/building.html

And finally a quick note about “build.conf.sample” file in the root of source repository.

With this file you can tweak the number of threads used by the build scripts. Just copy “~/synfig.git/build.conf.sample” to “~/synfig.git/build.conf” and adjust its contents according to your needs.

Didn’t know that, even though I’ve read that page at least once

I had in mind something like:
./2-build-debug.sh [package] [phase] optional:[--MAKE_THREADS=N]
but that will do the job.

Thank you!

Normally, you set global exports/environment BEFORE invoke the script, it would be more:
MAKE_THREADS=N ./2-build-debug.sh [package] [phase] optional

In this very case, MAKE_THREADS is overriden inside the script (line 49), but it would work with DEBUG=1 as prefix (lines 56-57)
