Problems building

[vkee]

Hi,

I'm running into issues trying to make. I am getting a error: ‘memcpy’ was not declared in this scope
return (char *) memcpy (__dest, __src, __n) + __n;

I do have have all the dependencies installed, including CUDA.

Error from Terminal.

Apparently something like -D_FORCE_INLINES is needed.

BVLC/caffe#4046
tensorflow/tensorflow#1346
opencv/opencv#6500

[xlz]

This will be fixed by #690.

@foong Yours is a different one. Open a new issue.

gcc later than 4.9 is not supported by CUDA 7.5 anymore. So use CUDA 8 instead.
