I have give my CMAKE files and my build progress in error.txt

I want to deal the problem

Hi Hailing,

I think this is due to missing cublas and cusolver libraries from the install. can you check you have libcublas.so and libcusolver.so files in /usr/local/cuda/lib64 directory. CMakefile seem to have the right settings, but compiler/linker is not able to resolve the symbols.

I have add target_link_libraries(${PROJECT_NAME}

PUBLIC

cusolver

cublas

cublasLt

cusparse

) into cmakelists.txt file ,but still have same problem. whilc is commoned by nivda in NVIDIA/CUDALibrarySamples: CUDA Library Samples (github.com). And I chose disenable the two libs in gpu coder project like the img. But there still have a problem.

like:

/home/jetson/JETSON_CODE/MATLAB_ws/R2023b/E/file/CODE_WORK_SPACE/OPENCV/matlab_code/JETSON/jetson_main_img_3d_1_1/codegen/lib/img_to_3d/img_to_3d.a(img_to_3d_terminate.o): In function `__sti____cudaRegisterAll()':

tmpxft_000032ab_00000000-5_img_to_3d_terminate.cudafe1.cpp:(.text.startup+0x20): undefined reference to `__cudaRegisterLinkedBinary_54_tmpxft_000032ab_00000000_6_img_to_3d_terminate_cpp1_ii_22357f4f'...

I give it in error.txt. I also submit my new cmakelists.txt. I use jetson nano as my Operation platform. It supports cuda. The version of cmake is 3.28.1.

and thank you for your attention.
