[Insight-users] why does itk 2.x require g++ 3.4 and greater ?

[Luis Ibanez]

Hi Nils,


     ITK 2.x  *does not* require gcc 3.4 or higher.


We build ITK with gcc 3.3 and gcc 2.95 on a Nightly basis.


The problem with gcc 3.3, 3.4 and the versions of libstdc++
are most likely a misconfiguration of your system.


You may want to double check on the dependencies that you
get when you configure VTK for building it with gcc 3.4


Please let us know if you have further questions.


    Thanks


      Luis
