Hi, I have some problems getting profiling to work with a ghc-6.4 that I compiled from source. Everything seems to work all right, but the output doesn't contain any times; in time profiling (+RTS -p) times are all zeros, with heap profiling, I never get any 'samples' output, just an empty one. I can go back to see if there's anything I configured incorrectly, but this sounds weird enough that I thought I'd ask the list if this is a known problem (preferably with a known solution). Is it? (ghc 6.4 compiled from source with ghc 6.2.2 on Ubuntu 5.04, Linux 2.6.12-rc2) -kzm -- If I haven't seen further, it is by standing in the footprints of giants
