[Insight-users] Re: itkMinimumMaximumImageCalculator

[Chad Washington]

Thanks for the suggestions, but unfortunately I received the same errors.  So, 
I removed all code associated with the Min/Max calculator except for the 
inclusion of the header file, i.e. the only reference to the calculator in my 
code is the line

#include other things
#include "itkMinimumMaximumImageCalculator.h"
#include other things

This gives me the following compilation error:
In file included from
	Insight/Code/BasicFilters/itkMinimumMaximumImageCalculator.h:110,
	mie.h:29,
	mie.cxx:57:
Insight/Code/BasicFilters/itkMinimumMaximumImageCalculator.txx:47:45: macro 
"min" requires 2 arguments, but only 1 given
Insight/Code/BasicFilters/itkMinimumMaximumImageCalculator.txx:48:45: macro 
"max" requires 2 arguments, but only 1 given
Insight/Code/BasicFilters/itkMinimumMaximumImageCalculator.txx:78:45: macro 
"max" requires 2 arguments, but only 1 given
Insight/Code/BasicFilters/itkMinimumMaximumImageCalculator.txx:102:45: macro 
"min" requires 2 arguments, but only 1 given

However, when I changed this to where "itkMinimumMaximumImageCalculator.h" was 
the first included itk file, then these errors were resolved.  I then added 
the Min/Max calculations back into my code, compiled, and received no errors.

I'm not sure why there is this dependence on #include ordering, but I thought 
you might like to know.
