Unable to compile with ZFP_WITH_CUDA=TRUE on Windows #244

Open kminemur opened 1 week ago

kminemur commented 1 week ago

Hi team,

I'm trying to compiler zfp with CUDA on Windows system, however I'm getting link error of "LINK : fatal error LNK1104: cannot open file 'stdc++.lib'". I could compiler it on Ubuntu22.04 environemt.

Does zfp with CUDA only support Linux environment?

Steps install CUDA Toolkit 12.5 git clone zfp cd zfp; mkdir zfp; cd zfp cmake .. -DZFP_WITH_CUDA=TRUE cmake --build .

There's no reason I'm aware of why zfp cannot be built with CUDA support on Windows. We unfortunately do not have a CUDA-capable Windows machine that would allow us to reproduce the issue, but it seems unlikely that the issue is related to zfp.

Perhaps you can include the full CMake output to see if it gives any other hints? Also, what version of CMake are you using? What host compiler and version? Is the compiler compatible with CUDA 12.5? See https://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows/index.html for requirements. Can you successfully build any of the CUDA code samples?

cmake out log is as follows:

So the CMake warning is related to #232, which we will fix in the next release. Still, CUDA is found, so presumably that's not the cause.

From NVIDIA docs, your compiler should be compatible with CUDA 12.5. But please do attempt to build one or more of the CUDA code samples to verify that this is not a zfp specific issue. It would also be instructive to test if zfp builds with CUDA disabled (-DZFP_WITH_CUDA=OFF).
