Hi Daniel, thanks for the explanations. I have tried reinstalling with cabal --reinstall gtk, having set split-objs: True in ~/.cabal/config before.
However, the compile yielded a single .o file again,
Yes, there's the single .o file for the package, the question is, what's in the archive (libHSxxx.a). Rule of thumb, if it's more than twice as large as the HSxxx.o, it contains the split object files (you can verify by looking at it with nm).
Ah .. ok, stupid me ;) the archive is more than twice the size, and ar tells me about a lot of object files inside it. So compiling with -split-objs appears to have worked out. 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?
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.
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. --Christian
