Hi Brad, Thanks for the information, that makes a lot of sense. Here's hoping that CUDA 9 fixes the problem! Sadly it's a bit of a showstopper right now, but I'll be sure to try this again in a future version.

Unfortunately we have to strip them out to work around a bug in CUDA's VS integration. The -Xcompiler options are parsed for inclusion in AdditionalCompilerOptions in the .vcxproj file by flag map entries here: https://gitlab.kitware.com/cmake/cmake/blob/v3.9.0-rc3/Source/cmVS10CudaFlagTable.h#L3-6 Then a subset of the options that have dedicated elements defined by the CUDA VS integration are extracted by flag map entries here: https://gitlab.kitware.com/cmake/cmake/blob/v3.9.0-rc3/Source/cmVS10CudaHostFlagTable.h Ideally we should then leave the rest in AdditionalCompilerOptions, but CUDA's VS integration puts them in the wrong place and breaks builds. Therefore we have to drop them: https://gitlab.kitware.com/cmake/cmake/blob/v3.9.0-rc3/Source/cmVisualStudio10TargetGenerator.cxx#L2508-2510 We've reported this to NVIDIA but can't take the workaround out until a version of CUDA comes out that fixes it. -Brad ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
