library is linked but reference is undefined

Question

I\'m trying to compile an openCL program on Ubuntu with an NVIDIA card that worked once before,

#include 
#include 
#include &         


        

Answer 1

Alternatively you can add the header and library path to your global variables.

export CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/usr/local/cuda/include
export LIBRARY_PATH=$LIBRARY_PATH:/usr/lib/nvidia-current

You can also try to set

export PATH=$PATH:/usr/local/cuda/bin

It should be possible to run now

g++ opencl.cpp
