should not be necessary for a subset of flags (Xcompiler works fine without it, even if the default values are pointless).<o:p></o:p></span></p>

</span><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.exe" -gencode=arch=compute_20,code=\"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
GPU Computing Toolkit\CUDA\v8.0\include" -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\include" -G --keep-dir x64\Debug -maxrregcount=0 --machine 64 --compile -cudart static -Xcompiler="/EHsc -Z7 -Ob0" -g -D_WINDOWS -Xcompiler "/EHsc /W3
/nologo /Od /FS /Zi /RTC1 /MDd /GR" -o A.dir\Debug\a.cu.obj "D:\jsroemer\projects\cuda-pdb-test\a\<a href="http://a.cu" target="_blank">a.cu</a>"</span><o:p></o:p></p>
