Slicer:Slicer 2.6 Building Leopard

When you run ./slicer2/Scripts/genlib.tcl, you will get errors when trying to build incrTcl.

Running genlib.tcl again, the build should continue until partially through the ITK build, and then you will see this error:

This is due to a bug in ITK 2.6. You can either upgrade to a newer version of ITK, or open up the file:

slicer2/Lib/darwin-x86/Insight/Utilities/vxl/core/vnl/vnl_math.cxx

in a text editor, and remove line 66:

# define isnan(x) __isnand((double)x)                                                                                                                  

and replace it with the following:

#define isnan(x) std::isnan(x)

Save the file and run genlib.tcl again.

Next, you'll get the following error:

...etc.

You can just ignore this error. It will disable SlicerIO, but shouldn't affect other portions of Slicer.
