fatal error "math h" No such file

[alianza]

Hey,

alianza@alianza-Latitude-XT3:~/caffe$ make pycaffe

NVCC src/caffe/solvers/adam_solver.cu
In file included from /usr/include/crt/math_functions.h:8835:0,
                 from /usr/include/crt/common_functions.h:271,
                 from /usr/include/common_functions.h:50,
                 from /usr/include/cuda_runtime.h:115,
                 from <command-line>:0:
/usr/include/c++/6/cmath:45:23: fatal error: math.h: No such file or directory
 #include_next <math.h>
                       ^
compilation terminated.

System is UBUNTU 18.04

Compiler is CUDA GPU

I have checked the file math.h and it is present in the specified directory.

I believe the issue has to do with the #include_next header as opposed to it just being #include, but thats just speculation.

would appreciate help
