llvm dev - Dec 2009 - [LLVMdev] GCC frontend binaries + Darwin10 (Mac OS X)

Hi,

if I want to use 'llvm-gcc' I get:

dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib
  Referenced from: /Users/me/llvm/gcc/bin/llvm-gcc
  Reason: Incompatible library version: llvm-gcc requires version 8.0.0 or
later, but libiconv.2.dylib provides version 7.0.0
Trace/BPT trap

So I installed MacPorts and 'libiconv', but I get the same error
message. But it _should_ work, because

otool -L /opt/local/lib/libiconv.2.dylib

gives me:

/opt/local/lib/libiconv.2.dylib:
	/opt/local/lib/libiconv.2.dylib (compatibility version 8.0.0, current version
8.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version
125.0.0)

Any hint what went wrong?

Thanks a lot,
Nico

Fun. My guess is that it's still not loading the right libiconv, but not
sure ultimately. I've never seen that problem (and I do run with macports
and libiconv on my system).

At any rate, we do have binaries for that system that are shipped with the
developer tools.  Otherwise I would try building and running on the same system.

Did you follow the macports migration guide
(http://trac.macports.org/wiki/Migration
) after upgrading from 10.5 to 10.6? I seem to remember having a  
similar problem and fixing it by recompiling everything on 10.6

Not at all ;-)

I think installing libiconv with +universal makes that problem go away.

Perhaps a 32/64 bit mixup? If one is 32-bit and the other is 64-bit,  
that could cause something like this. Use "otool -vf" and "otool
-vh"
to check which slices are built for the programs.
