CMake Linking Issues

Accelerated Computing CUDA CUDA NVCC Compiler

Hello,

I am working on an Orin NX 8GB Jetson and I have an issue within CMake getting the cudnn library to link properly. What I do have working so far is an nvcc command in the terminal properly compiling and linking the same main.cu file.

The working nvcc invoked at the command line is:

nvcc main.cu -L.. -L/usr/local/cuda-12.6/lib64 -I/usr/local/cuda-12.6/include/ -I.. -lLoadSafeLandingNetwork -lcudnn -lcublas

This yields the default executable “a.out” and I get the output I expect when I run it.

Now, if I move this into a CMakeLists.txt that should be operating identically (so I think…), I get linking errors on various functions:

  • __sti____cudaRegisterAll()
  • cublasCreate_v2()
  • cudnnDestroy()
  • etc…

The CMakeLists.txt I’ve created to replicate the command line nvcc invoke is:

project ("CMakeCUDA_Test" ) include(CheckLanguage) check_language(CUDA) if(CMAKE_CUDA_COMPILER)     enable_language(CUDA)     if(NOT DEFINED CMAKE_CUDA_ARCHITECTURES)       set(CMAKE_CUDA_ARCHITECTURES 75)     endif()     find_package(CUDAToolkit)     message(STATUS "Enabled CUDA Compiler")     message(STATUS "${CUDAToolkit_BIN_DIR}")     message(STATUS "${CUDAToolkit_INCLUDE_DIRS}")     message(STATUS "${CUDAToolkit_LIBRARY_DIR}") else()     message(STATUS "No CUDA Compiler found") endif()  # Add source to this project's executable. file(GLOB test_SRC "main.cu")  add_executable (cmake_test ${test_SRC})  # Add libraries target_link_directories(cmake_test PUBLIC ".." ${CUDAToolkit_LIBRARY_DIRS}) target_include_directories(cmake_test PUBLIC ".." ${CUDAToolkit_INCLUDE_DIRS}) target_link_libraries(cmake_test -lcudnn -lcublas "libLoadSafeLandingNetwork.a")

Which yield the output when CMake runs:

jetson@ubuntu:~/Documents/safe_landing/LoadSafeLandingNetwork/examples/build$ cmake ../ -- Enabled CUDA Compiler -- /usr/local/cuda-12.6/bin -- /usr/local/cuda-12.6/targets/aarch64-linux/include -- /usr/local/cuda-12.6/lib64 -- Configuring done (0.1s) -- Generating done (0.0s) -- Build files have been written to: /home/jetson/Documents/safe_landing/LoadSafeLandingNetwork/examples/build

And after generating the Makefile and running a simple make command in the CMake build folder I get the following output:

I’ve double checked the include and library directories and see that the CMake output matches the command line invoked -L and -I flags. So it seems like the libraries should be found and now there is something else keeping them from linking? Am I missing something that needs to be done higher up in my CMakeLists.txt to prepare the linker?

Any help is greatly appreciated. Thank you.
