[Insight-developers] [Insight-users] Problems with ITK

[Cory Quammen]

Gabriel,

You must be trying to use CUDA in your project. I wouldn't be
surprised if the CUDA compiler has trouble with all the features of
C++ that ITK uses.

The good news is that you don't need to define your main function
inside a CUDA source file. You can instead compile only your CUDA
source with the CUDA compiler, and all your regular C++ code as C++
files. Just put the CUDA code in a .cu file, put your main C++ code in
a .cpp file, then add all the source files to your call to
CUDA_ADD_EXECUTABLE. CMake should figure out how to compile them
automatically.

Hope that helps,
Cory
