[Insight-users] Compiling ITK on Windows: GIPL problems

[Luis Ibanez]

Hi Raghavendra,


Your code looks good, except for the line


         using namespace std;


Please DO NOT USE this lines in any code.
It is only calling for trouble. Your cout's
already have the "std::" as they should, so
you can get rid of the "using namespace".

------

I agree with Mathieu, in that the possible source
of the problem is the absence of a ".gipl" extension.

Please let us know if your files are using the right
extensions.

If the extensions happen to be correct, this may
indicate a problem with the Analyze image reader,
in which case we will track it down.



Thanks


Luis
