Hi all. Valery: You unfortunately cannot just use -parallel with the normal GHC compiler. You need to download one which is actually meant to be used in parallel (namely GPH). You can find information about it here: http://www.cee.hw.ac.uk/~dsg/gph/ GHC Folk: I think a better error message is in order here. I think in the past two weeks three people have tripped over this and emailed this list. Perhaps just when -parallel is specified in a non GUM/GranSim-ified GHC, it barfs with "GHC not built for parallelism" in the same way that a GHC not built for interactivity will barf on --interactive. - Hal On Mon, 4 Nov 2002, Khamenia, Valery wrote:
Hi ghc world,
why option -parallel leads to error while without this option everything was compiled OK?
