Simfactory has for some time supported a
-j option that would let one change (or speficy eg on a freshly configured laptop) how many parallel processes to use when building. This functionality was reviewed and accepted in
#1928 however to date no machine.ini file actually implements it so that user choices for
-j are ignored.
Unless objected until 2019-04-14 I will go ahead and replace constructs like this:
make = make -j 17
makejobs = 17 make -j @MAKEJOBS@
simfactory/bin/sim build -j 42at build time (or in their
defs.local.iniif they so choose).
To recap the discussion in
#1928: if neither the machine database nor the user specifies a value for
@MAKEJOBS@ then it defaults to 1 which is how
make alone would behave.
As a side effect (and partial driver for this) this would mean that one can change the tutorial instructions from the odd
simfactory/bin/sim build --mdbentry make 'make -j2'
simfactory/bin/sim build --jobs 2
