</span></span></span><u></u><span lang="EN-US">Trying to circumnavigate this issue by using “/Z7” instead of “/Zi” does not work, Zi is always used (replicable in any project with CUDA)<br>
<br>
Replication steps: Replace -Zi or /Zi in CMAKE_*_FLAGS* (CUDA, CXX, C) by -Z7 or /Z7. Build and see several warnings like “cl : Command line warning D9025: overriding '/Z7' with '/Zi'” in the output window.<br>
And do the flags in the –Xcompiler make sense at all in VS? The CUDA build tools seem to determine these automatically anyways… for example I get the following call in the above scenario:<br>
<br>
"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\bin\nvcc.<wbr>exe" -gencode=arch=compute_20,code=<wbr>\"sm_20,compute_20\" --use-local-env --cl-version 2015 -ccbin "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64" -I"C:\Program Files\NVIDIA
