[Insight-users] help about macro "max" requires 2 arguments, but only 1 given

[Di Xiao]

Dear All:

   My project is runing in Redhat 8.0, gcc-3.2-7.
The problem I met is once I included  "itkPointSet.h" in the project, it 
will give error as:

In file included from 
/usr/local/include/InsightToolkit/Common/itkPointSet.h:26,
from mainwin.ui.h:88,
from mainwin.cpp:23:
/usr/local/include/InsightToolkit/Common/itkPointLocator.h:96:71: macro 
"max" requires 2 arguments, but only 1 given

I find the same problem ever talked in the mailing list as attached.
But I didnt use any "max" variable in my program. And I checked
"undef min" and "undef max" is defined in itkNumericTraits.h.

Can anyone give suggestion how to solve it?

Thanks

Xiao Di



Attached:  Disscussed topic

HI Chad,

Please follow Paul's advice. He is right.
min and max are defined in windows standard
headers (for example).  ITK undefine them
in itkNumbericTraits.h in Insight/Code/Common.

Strange that this undef is not working for you,
it should make this platform independent.

We probably don't have a dashboard with gcc 3.2.3....


Regards,


   Luis
