hi,
I would like to cross-compile on Ubuntu20.04 to my Jetson board,Can cuda cross-compile with arm64-sbsa? Or which compiler should I download if I want to implement cuda cross-compile?
thanks

Hi,

arm64-sbsa is a different system.
Please install the cross-compile toolkit from the SDK manager.

The package is also available in the below link: cuda-cross-aarch64*
https://repo.download.nvidia.com/jetson/

Thanks.

If I install CUDA-cross-aARCH64 successfully, can I cross-compile cuda?

5

If cuda-cross-aarch64 is installed successfully, where can I see a successful installation sign?

6

Hi,

You can check it with $ aarch64-linux-gnu-gcc -v.
Thanks.

7

Do I cross-compile cuda using nvcc or aarch64-linux-gnu-gcc or CUDA-Cross-SBSA?

8

hi,Can I find nvcc when I install cuda cross compiler without cuda

9

Hi,

You will also need a CUDA toolkit.

GPU code should be complied with nvcc and the corresponding flag.
Ex. -gencode arch=compute_72,code=sm_72 for Xavier.

CPU code should be complied with aarch64-linux-gnu-gcc.

Thanks.

hi,
How should I configure cmakelist when compiling a project with cuda code?
thanks.

11

hi,
Are there any cuda cross-compilation examples you can share with me? I’d like to see how your cmakelist is configured
thanks.

nvcc fatal : Unknown option '-gencode arch=compute_72,code=sm_72
After I add this sentence, I will prompt this error, do you know how to solve this error, or what caused this error?

13

Hi,

Please find an example below:
https://docs.nvidia.com/vpi/sample_cross_aarch64.html

Add set the GPU architecture with the following command:

set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS}; -O3)
set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS}; -gencode arch=compute_72,code=sm_72)

Thanks.

Do you know how to solve this error when cross-compiling cuda programs

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi,

Do you build it in a clean environment?
Could you run make clean and try it again?

Thanks.
