I have seen, however, that I have 2 versions of gtk (0.11.2 and 0.11.0) on the system. I will try to find out which one was actually used when I called "ghc --make guiMain"; how would I go about that?
Normally, ghc picks the later version. When compiling, you can see which version is used by giving the appropriate verbosity flag (-v2 or greater). After the fact, the only way I know is $ nm executable | grep stginit_gtk | more (or less) and then you'll see the z-encoded package version, lines like 080ca5dc T __stginit_gtkzm0zi11zi2_Stuff for gtk-0.11.2.
and recompiling and re-linking my little program does not change its size ...
Possibly the packages have been built with -spilt-objs originally, or your GHC doesn't support split-objs, in either case, sorry for the inconvenience
:-/
gtk contains apparently hundreds of thousands of modules, so it may be the module-initialisation functions. Quick test:
$ nm yourexecutable | grep stginit | wc -l
I tried that, there are almost 900 matches.
Hm, shouldn't nearly take you to 20M.
Any other idea what I might be doing wrong?
Nothing, probably.
What ghc version are you using, on which platform (OS, arch), which packages does your executable need?
I am using Ubuntu 10.10, ghc 6.12.1, on a 4-core AMD Phenom. The program I am compiling needs these packages: gtk, Text.Parsec, Time, Database.HDBC.Sqlite3, Locale, Data.ByteString.Lazy.
No obvious suspect. Depending on how curious you are, you could split off small sub-programmes to see what's taking a lot of space. But that's going to be tedious. You could ask on IRC (#haskell) whether anybody knows about huge executables with gtk, or on haskell-cafe, on the gtk2hs mailing list, or you could open a ticket at http://hackage.haskell.org/trac/gtk2hs/ or http://hackage.haskell.org/trac/ghc/newticket?type=bug whichever you consider more likely to be responsible (you needn't create an account for either bug-tracker, both have guest accounts with the guest password in plain view - though you may need to look for it a bit). But first ask elsewhere.
