opencv cmake not building I've been trying to build OpenCV in a mac (Yosemite 10.10) using cmake-gui and the compilers gcc,g++ and gfortran given by MacPorts. 
I HAVE to use those compilers. 
I configured WITH_OPENCL to be OFF and generated the binaries. But when I try to make it in the terminal I get the following error :

I do not know why I'm receiving this error. Is there some other configuration I should be doing? Can anyone help me out with this?
So I'm a bit late, and with new problems to solve anyway.
My issues was that my main folder which contained the binaries had a space in the name.
And ocl has issues with those. 

I removed the space and it built smoothly.

I did NOT expect this.
