Hello
when i use cmake to complie my project,it have complie successfully,but when i got the link stage
but i got the probelm like this
ld: not found. -lcusolver: No file or directory
ld: Not found -lcublas: No file or directory
ld: Not found -lcufft: No file or directory
when i add the libs in the shell path,this time it doesn’t works

it seems that i need add the libcusolver.so,libcubals.so,libcufft.so in the CmakeLists.txt,i know i can add this by -L/path/to/libraries/…,however how can i add it in the cmakeLists.txt
–best wishes

Are you using enable_language(CUDA) or find_package(CUDA)? The latter is deprecated and you should use the CUDA language instead. I think some of this comes from CUDAToolkit though?

All these libraries have target representations provided by the find_package(CUDAToolkit) module.
You would link to the CUDA::cusolver target which knows where the actual library is on disk.

i use the hpc_sdk,i can find the cusolver.so,cublas.so,cufft.so,but i can’t install the CUDAToolKit,so could tell how to add the shared time library in the project

find_package(CUDAToolkit) is aware of the hpc sdk layout and will find the components CUDA toolkit components inside of it.

Edit: You will want to use the newest version of CMake possible ( at a minimum 3.21 ) to get HPC SDK support from find_package(CUDAToolkit).

If for some reason you can’t upgrade CMake, the HPC SDK also ships with the NVHPC module which will bring in support for these libraries.

That can be used like:

  project(helloworld CXX)

  set(NVHPC_CUDA_VERSION 11.0)
  find_package(NVHPC REQUIRED COMPONENTS MATH)

  add_executable(helloworld "helloworld.cpp")
  target_link_libraries(helloworld PRIVATE NVHPC::MATH)

The NVHPC::MATH target will ensure you link to cublas, cusolver, curand, cusparse, etc.
