Hi! I'm trying to install opencv 2.4.5 on Mac 10.8 with no success. I'm using 2.4.5 opencv because it is the last but If there are some issues on that version i can downgrade, no problem. (I have already installed command line extension from Xcode and CUDA toolkit from NVIDIA)
I'm stucked in setting the right compiler for CUDA.
What I've done is: download opencv, run CMAKE, run make, get the error:
clang: error: unsupported option '-dumpspecs'
(with manual cmake and with macport same error)
So, after some google i've found that the problem could be CUDA_HOST_COMPILER. I've tried to change it in /usr/bin/gcc, /usr/bin/llvm-g++ and i get on but after a little while I get another error:
cc1plus: error: unrecognized command line option "-Wno-narrowing"
I can post all output from cmake and make, if it needed.
What can I do? I need to compile opencv with cuda, but I don't have other need like a particular version of opencv or gcc or clang or llvm (and I normally develop under ubuntu so I don't understand deeply the differences between those compilers).
this is my system settings:
OS X 10.8.3 (12D78)
