'make --jobs all', 'make --jobs test', and concurrency

[David Christensen]

makemaker:

I have a computer with a multi-core processor, Debian 7, and Perl
5.14.2. 'make --jobs all' seems to run concurrently, but 'make --jobs
test' seems to be single-threaded. Is there a way to run tests
concurrently?


TIA,

David

Hi David,

make test is a single make target so make -j or make --jobs won't help here.
What might help is the HARNESS_OPTIONS environment variable:

HARNESS_OPTIONS="j9" make test

See "perldoc Test::Harness":
