if (status != cutlass::Status::kSuccess) { return -1; }

return 0; } Expected behavior When I was using the CUTLASS Library following the Quick Start documentation, I encountered this problem when compiling its examples as instructed

Environment details (please complete the following information): compiler-args " -I/content/cutlass/include -I/content/cutlass/tools/library/include -I/content/cutlass/tools/util/include --expt-relaxed-constexpr"

Additional context I looked up the information and found that there was a problem in the linking process, but I don't know how to solve it. Could you please help me

[thakkarV]

please show your complete cmake config command you are using and provide more details about your system environment you are building on

[LANSHANGH]

The cmake command I use is the Initial build steps in quickstart.md.

`$ export CUDACXX=${CUDA_INSTALL_PATH}/bin/nvcc

$ mkdir build && cd build

$ cmake .. -DCUTLASS_NVCC_ARCHS=75 # compiles for NVIDIA Hopper GPU architecture`
