I’m attempting to upgrade our engine based on PhysX 3.2.2 in VS 2010 to use VS 2015, and I cannot link against the SDK libraries. I’ve had success in the past linking PhysX 3.2.5 in VS 2013, but have not had the same luck here. In a desperate attempt, I tried building PhysX 3.3 from GitHub, but the SDK fails to build with a handful of linker errors I’m not sure I can fix on my own.
Has anyone had any success integrating PhysX into a project built with VC14? Ideally, I’d like the 3.2.2 or 3.2.5 binaries compiled in VS 2015 with /MD, but if that’s not possible, I’d settle for some help getting 3.3 to compile.
I’m on the same road, disable /WX and you have to include to remove the “abs” error then you have the debug lib compiled but I still have one error for the release about nvcuda.
Debug builds fine for me, but the other configs all give “LNK2019: Unresolved External Symbol” for calls to NpScene::multiQuery on lines 440, 453, and 467 in PhysX::NpBatchQuery.cpp.
You right, the nvcuda is a warning :

You can get it to compile in vs2015. Just change all <math.h> to and find the comment
“// explicit instantiations for multiQuery to fix link errors on android”
then enable the block underneath it.

Thanks! Worked for me.
However, I also had to add the /Wv:18 flag because I was getting warnings and errors like this:
