[vtkusers] Simple Linking Question

[John Platt]

Hi Mark,

If you are linking MFC as a static library, try compiling VTK & your MFC
app with the static CRT (/MT). From distant memory, the MFC static
library will link the static CRT which conflicts with the dynamic CRT
you have specified.

HTH

John.

Hi John,

I just recompiled VTK with these settings:

Use of MFC: Use MFC in a static library.
Runtime Library: Multi-threaded DLL (/MD)

Now 5 line test program uses the same exact settings. But I still get
the two linking errors complaining that new and new [] are already
defined! What could I be missing?

Here is my sophisticated test app again:

#include "vtkRenderer.h"
 
int main()
{
     vtkRenderer *renderer = vtkRenderer::New();
     return 0;
}
