That's to be expected, because unfortunately, profiling is not a "transparent" operation; you have to compile things differently and certain features don't work. You might have better luck doing a slow test run, with WAY=prof (there are actually a number of other cases too, such as prof_hc_hb, etc, see testsuite/config/ghc) Edward Excerpts from Jan Stolarek's message of Thu Sep 19 02:30:53 -0700 2013:
I need to run testsuite with profiling turned on. When I run
make WAY=normal EXTRA_HC_OPTS="-prof -fprof-auto -rtsopts"
lots of tests are failing with:
Dynamic linking required, but this is a non-standard build (eg. prof). You need to build the program twice: once the dynamic way, and then in the desired way using -osuf to set the object file suffix.
I only added "GhcLibWays += p" to "quick" section of my build.mk. I guess this error message has something to do with DYNAMIC_BY_DEFAULT - I could probably get this right with a trial and error approach, but I'd rather know what I'm doing. Can anyone tell me what is going on and what do I need to do to make this work?
