I have written a small wxHaskell application. Since wxWidgets seems to be required to be linked dynamicly, I have to add the wxWidgets dlls. Those make a total of about 25MB, wow.
Now the compiled exe (compiled with ghc -O2) has size 15MB. In total I am at about 50Mb, which is just to much.
Why is the exe so big? Has anyone a suggestion on how to reduce the total size? Bindings for large C libraries contain a great number of Haskell wrapper functions for C functions. Looks like GHC is not terribly efficient in terms of size of generated code. Your tiny application gets statically

In case you're having multiply haskell binaries using wxWidgets you can use GHC's dynamic linking feature. http://www.haskell.org/ghc/docs/7.6.3/html/users_guide/using-shared-libs.htm.... This way actual binaries would be small but would have an additional run-time dependency. And my question. Does GHC try to exclude unused symbols from Haskell libraries it links to application code?
