Hi Ben
I built from source and ran the tests on my Mac and found some
problems. I'm not sure if the failing tests have been ran successfully
by others on this platform. I did "make slowtest". Maybe the problem
only happens on my machine.
I'm new to running the testsuite and not sure how the sleep settings on my
computer affect long running computations.
- If I want to run a long running test such as "make slowtest" overnight
will my computer go to sleep preventing the test from running? i.e. should
I invoke it with something like "caffeinate -i make slowtest" ?
I almost didn't run the tests assuming they had been run as part of the
release process but then I guessed that maybe slowtest had not been run. It
would be a pain but would it be worth documenting which tests had been run
on which platforms?
I assume I should file a bug for the following?
make TEST=dynamic-paper WAY=profasm
