[Insight-users] Itk error under linux

[Luis Ibanez]

Hi John,

Did you set the GCC flag:

            -ffloat-store

??

Check the values of

            CMAKE_CXX_FLAGS

and

             CMAKE_C_FLAGS

in the CMakeCache.txt file that cmake generates
in the binary directory where you are trying to build ITK.

If you see the flag there, then you can remove it by
editing the cache.

The simplest way to edit the cache is to go to the
binary directory and do:

                make  edit_cache

then use the "t" key for toggling to the Advanced mode
and use the "/" to search for the "CXX_FLAGS" and the
"C_FLAGS" strings.



----

For an example of how to use ITK in your project,
please look at :

         Insight/Examples/Installation

This code is described in the ITK Software Guide

    http://www.itk.org/ItkSoftwareGuide.pdf

you should also look at the Tutorials:

   http://www.itk.org/ITK/help/tutorials.html

in particular the "Getting Started" session:

    http://www.itk.org/CourseWare/Training/GettingStarted-I.pdf

It will guide you step by step on how to download,
configure and build ITK, as well as, on how to use
it from your own project.


    Regards,


        Luis
