[llvm-dev] problem on compiling cuda program with clang++

[Justin Lebar via llvm-dev]

Hi, it looks like you're compiling CUDA for an ARM host?  This is not
a configuration we have tested, nor is it something we have the
capability of testing at the moment.

You may be able to make it work by providing the appropriate -isystem
flags to clang so that it can find your headers, but who knows, it may
be more complicated than that.

Regards,
-Justin
