When I cross compile a .cu file,the system give the following error information:

Hi Ge-Baoshan,

Maybe you can refer to https://devtalk.nvidia.com/default/topic/978541 and try with nsight first.

Hi,vickyy
https://devtalk.nvidia.com/default/topic/978541 'problem is different from mine. I run into cross-compiling .cu file. Cross-compile, not other problem.

Hi,

You can use JetPack-Compile CUDA Samples options to automatically compile CUDA sample.

If you want to compile it manually, please remember to add the target information in the command:

EXTRA_LDFLAGS=--unresolved-symbols=ignore-in-shared-libs TARGET_ARCH=aarch64 make

Thanks.
