Affine Gap fails to compile in OSX Mountain Lion about dedupe HOT 2 CLOSED

This appears to be an issue with clang, the default compiler for OSX from Lion (10.7) and on.

This can be solved in two ways:

• change the default compiler set in xCode by adding the following lines your .bash_profile

#Set LLVM GCC as the default compiler for the system
export CPP='llvm-gcc-4.2'
export CC='llvm-gcc-4.2'
export CXX='llvm-g++'

• Run setup.py by specifying the compiler in the command line

LDSHARED="gcc-4.2 -Wl,-F. -bundle -undefined dynamic_lookup" CC=gcc-4.2 python setup.py install

from dedupe.

Update: we updated cython and rebuilt the affinegap.so and it now compiles using clang

from dedupe.
