For anyone following this: The XCode ld script is complex, and has mac specific defaults early in the search path specification, and I probably don't want to change these. A library in a default path is the wrong libgmp.[dylib | a]. My solution: do a ln -s libgmp.a lib-h-gmp.a in the /Library/Frameworks/GHC.Framework/..../usr/lib folder. Then add lib-h-gmp.a to my Xcode project. Compiled, linked, and ran and got the right output. Thanks to everyone who helped. John V. On Wed, Oct 07, 2009 at 10:38:53AM -0700, John Velman wrote:
This is probably an Xcode problem now, rather than a strictly Haskell problem.
There are a bunch of libgmp.a and libgmp.dylib files in existence on this computer, some in /usr/local/lib, or linked from there.
I've got my errors down to references in libgmp, whether or not I try to include libgmp.a in the project.
Whenever I try to add libgmp.a, or libgmp.dylib to my project, I get the error message:
---------- ld warning: in /Developer/SDKs/MacOSX10.5.sdk/usr/local/lib/libgmp.dylib, file is not of required architecture ---------
followed by a list of undefined symbols, all of which (well, all I've checked!) are defined in the Haskell Platform version of libgmp.a
I'm sure there must be a way around this in the Xcode IDE, but haven't found it. I'll take the question to the Xcode mailing list.
Thanks to all for help on this. I'll let you know how it works out!
Best,
John Velman

Note that library order matters; libgmp.a should probably be last on the command line.
