Testsuite with profiling

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? Janek
