*is* treated as a CUDA file (good news) but we either didn't add include path to clang headers, or the headers are not where they should be.</div>

Hello<br>
<br>
I am attempting to write a static analyzer for CUDA using the Clang infrastructure.<br>
<br>
After writing a simple tool, and giving it the example CUDA file in <a href="https://llvm.org/docs/CompileCudaWithLLVM.html" rel="noreferrer" target="_blank">
https://llvm.org/docs/CompileCudaWithLLVM.html</a> , I get the following error:<br>
<br>
fatal error: '__clang_cuda_runtime_wrapper.h' file not found<br>
<br>
so far this happens with both libtooling and libclang. I have tried using clang to compile the same CUDA file and it works.<br>
I am currently linking against clang sources from the trunk, but this also happens with Clang version 6.<br>
I currently have CUDA 10 installed on this computer. <br>
<br>
Any help would be appreciated.<br>
<br>
Regards<br>
Franklin<br>
