[Insight-developers] Compile errors in GPUCommon

[Bill Lorensen]

The following code does not compile:

#include "itkGPUImageDataManager.h"
#include <cstdlib>

int main ( int , char* [] )
{

  return EXIT_SUCCESS;
}


------------------
I thought I could fix it, but seems like the C++ is above my pay grade.

I get these errors on my Mac.

If I add
#include "itkGPUDataManager.h" in itkGPUImage.h I get different errors:
