If you are building with nvcc on OS X and get errors along the lines of "clang error: unsupported option '-dumpspecs'" - welcome to the new build world.
The best fix I've found so far is to replace the /usr/bin/cc and /usr/bin/c++ symlinks (which currently go to clang) with symlinks to llvm-gcc.
sudo rm /usr/bin/cc
sudo rm /usr/bin/c++
sudo ln /usr/bin/llvm-gcc /usr/bin/cc
sudo ln /usr/bin/llvm-g++ /usr/bin/c++
Try that out and see if it works! Please let me know if you find a better solution as well.
Are you using CMake 2.8-10?
ReplyDeleteI just encountered this error for the first time after configuring a new iMac with CMake 2.8-10 and CUDA 5.0.
I switched back to CMake 2.8-8, which I was using on a different Mac, and the error went away.
Note that the above "best fix" switches the compilers from clang to the older Apple compilers.
Ken: Cmake 2.8.10 is the first CMake version to respect cc and c++ as the default compilers on Mountain Lion. Previous version would use gcc and g++ on the Mac.
DeleteA better solution is make .. -DCMAKE_C_COMPILER=/usr/bin/llvm-gcc -DCMAKE_CXX_COMPILER=/usr/bin/llvm-g++
ReplyDeleteJames soln did not work for me.. still stuck on opencv
