Help! I have recently upgraded to Snow Leopard and upgraded to the

MacPorts for Snow Leopard (and I completely removed the old version of
MacPorts). I have tried to reinstall my ports. The ports download
and compile
fine, but when I try to link to them (for example, to freeimage.a)
in XCode, I get
the following messages:
Warnings: in /opt/local/libfreeimage.dylib, file is not of required
architecture
and then all the files that use the freeimage library produce
errors, saying
symbols not found. First of all, why does it return an error about
freeimage.dylib
when I am trying to link to freeimage.a? Also, what can I do to get
the
architecture problems to go away? Change settings in XCode? Change
settings in
MacPorts? This same type of error occurs for any library I try to
link to.
Any help would be greatly appreciated!
On Snow Leopard (in MacPorts and otherwise), software builds for
architecture x86_64 by default, as opposed to i386, which is what
Leopard and Tiger used by default on Intel Macs. If you are not also
building for x86_64 in Xcode, then that's the problem. You can either
rebuild your ports with the +universal variant to build both x86_64
and i386, or change build_arch to i386 in macports.conf and rebuild
everything for just i386, if you don't want to build 64-bit.
