Error compiling openCV-3.0.0 in Raspberry Pi Zero

edit

Dear all,

This is my first post in this forum, so I hope I am doing it correctly...

I am trying to install OpenCV-3.0.0 in a Raspberry Pi Zero following the instructions from pyimageresearch.com http://www.pyimagesearch.com/2015/12/...

I have followed all the steps but the virtual environment, and when the make process is about 10% I get the following error:

             from /home/pi/opencv-3.0.0/build/modules/core/precomp.hpp:49:
/usr/include/c++/6/cmath:45:23: fatal error: math.h: No such file or directory
 #include_next <math.h>
                       ^
compilation terminated.

Any ideas why?

I am using gcc and g++ 6.3.0

Thanks in advance. I really appreciate your help.

Marcos
