QUESTION
I am working on a CUDA C++ project that uses separable compilation, and I am having some trouble getting a thrust function to compile.
The project builds with no problem until the following function call is added.
...ANSWER
Answered 2017-May-02 at 13:26I finally figured it out!
The linking problem was due to the fact that cudadevrt
library was missing. The catch is that only adding -lcudadevrt
to the CUDA_NVCC_FLAGS
was not enough!
The problem goes away when linking the CUDA runtime device library to the CMake target as shown below:
target_link_libraries(project glut glew ${CUDA_cudadevrt_LIBRARY})
Obs1: the CUDA_cudadevrt_LIBRARY
variable is only made available on CMake versions above 3.7.2. Adding the line cmake_minimum_required(VERSION 3.7.2)
is a good idea.
Obs2: linking only to CUDA_LIBRARIES
as below does solve the issue only if you are using a CMake version above 3.7.2. On lower versions this variable exist but does not contain cudadevrt
library.
target_link_libraries(project glut glew ${CUDA_LIBRARIES})
