[Insight-users] can't build (ITK) hello world

[Luis Ibanez]

Hi John,

Not many ideas so far...


at this point the only suspicious observation is:

 > 6:

I assume that you build ITK with REVIEW ON
and with the option for using TRANSFORM FACTORIES ON.

Is that right ?


When you built ITK, did it when smoothly ?
did you got any warnings or error messages during the
build process ?

For lack of any other hits,
I would suggest you to try a clean build of ITK.

and then

a) build the HelloWorld example against the
    ITK build tree (not the installed one)

b) install ITK again,
    then build the HelloWorld example against
    the newly installed ITK



   Please let us know what you find,


     Thanks


        Luis
