CUDA Clang Error on Mac OSX 10.8

If you got the following error in compiling CUDA sample codes on your Mac OSX 10.8 

    

  1. clang: error: unsupported option '-dumpspecs'
    2. 

  2. clang: error: no input files
    3. 


The best solution lies here: devtalk.nvidia.com forum link 
 
This is what is been suggested and that worked for me: 


I had the same problem, thanks to martindeveloper. I found the 
findcudalib.mk but didn't have llvm-g++ (tried to install it but lost 
like 2 hours for nothing, because it doesn't come anymore with XCode and 
compiling it from llvm.org didn't work). Tried with gcc/g++ but nothing
 worked



Finally, I changed GCC ?= g++ to GCC ?= /usr/bin/clang (on findcudalib.mk) 
and everything worked fine (even if clang support is beta)
