if you are using GNU tools there is some magic to make them garbage-collect all the symbols in your executable before outputting the final code. you have to do some tricks with the segment headers so that it can GC individual functions but this should fix many of the image size problems at least in some cases. I agree that the GHC image sizes are a problem.
This is something we'd like to do, but haven't got around to. It's not just a case of adding the correct flags to gcc/ld unfortunately: GHC's assembly mangler needs to be taught how to generate the unique section names for each function. But then it's possible that we could remove the grotty -split-objs stuff that we use to split the libraries into small pieces. Cheers, Simon

Hi,
I just recently starting to use the ghc compiler and am astonished by the size of the executables. Out of interest, why are they so large? Is there any work in progress to make the resulting executable/object somewhat more "normal" in size?
I read in the Haskell mailing list archives discussions relating to reducing the barriers to broader acceptance of functional
general
programming community (in particular Haskell) - I would regard this as one of these barriers.

web for distribution, I run 'strip' on them and, if I'm on Linux or Win32, I run UPX on it as well. UPX is an executable packer, see http://upx.sourceforge.net/ for details. This routinely brings programs down from over 2 MB to around 250Kb which is small enough for me.
Hope this helps,
