Using Cuda Object Linking with Cmake

Question

Right now I am working on a project that uses the object linking capabilities of Cuda 5. Since the project is starting to get complex, I wanted to switch to using cmake to compile the code. However I can't seem to get object linking to work correctly for me. I ended up creating a toy version of the project which gets the same kind of errors as the original project. The toy project consists of a main file (TextureMain.cu) that calls a kernel function to run on the GPU. In each GPU thread an instance of a user-defined class (TextureFunc) is referenced, where the class exists in a separate folder from the main file. The class consists of a TextureFunc.cu and TextureFunc.h file in that folder. Here are the CMakeList.txt files I am using: In the project directory (contains src directory): ``` project(TextureMain) cmake_minimum_required(VERSION 2.8) find_package(CUDA REQUIRED) #------------------------------------------------------------------------------- set(CUDA_NVCC_FLAGS "-arch=compute…

Accepted Answer

How about linking`${CUDA_LIBRARIES}` to whatever targets using `.cu files?

For example in your src directory you could try:

```
cuda_add_executable(TextureMain TextureMain.cu)
target_link_libraries(TextureMain TextureFunc ${CUDA_LIBRARIES})
install(TARGETS TextureMain DESTINATION bin)
```
