#2553: Cactus' link command uses CPPFLAGS and CXXFLAGS

 Reporter: Roland Haas
   Status: open
Milestone: 
  Version: development version
     Type: bug
 Priority: minor
Component: Cactus

Comment (by Roland Haas):

Apparently using g\+\+ to link CUDA code is advanced use \(or at least was in 2014\). [https://developer.nvidia.com/blog/separate-compilation-linking-cuda-device-code/](https://developer.nvidia.com/blog/separate-compilation-linking-cuda-device-code/) It requires that one pre-links the object files to extract CUDA device code into a form that g\+\+ understands.
