[Haskell-cafe] Re: [Gtk2hs-users] Woes on MacOS 10.6 - linking issues -now working, but Glade is missing in v0.11 and v0.10.1 still won't compile SOLVED compile of 10.1

[Brett Giles]

Finally figured it out - leave the scripts for ghc and hsc2hs alone and do the configure for gtk2hs 0.10.11 like this:


./configure --with-hsc2hs='--cc-flag=-m32 --ld-flag=-m32'

(Issues with x86_64 vs i386 - but I have tried for three hours to get the magic combination of modifications to the ghc script, the hsc2hs script and environment variable to no avail).

I have no idea who's to blame here but I guess you should be trying to change your LD_LIBRARY_PATH or your DYLD_LIBRARY_PATH to /opt/sw since that contains the more complete version.
