[ITK] Fwd: ITK and python wrap problem

[Michka Popoff]

Hi

Some important questions first:

What was the warning for the library mismatch ?
On what OS are you installing ?
Is the libitkvnl_algo-4.7.so file present in /usr/local/lib ?

If the warnings were about the python library, it is quite important.
It may happen that you have two different python installations, and cmake is not able to find the right libraries.

I wrote some instructions to install ITK with python wrapping on Fedora http://www.itk.org/Wiki/ITK/WrapITKInstallFedora
There is a list of cmake flags you can set to help cmake find the right python, if it’s the problem you had.
I think the error is just because the library is not in your path. If you are using Fedora, just follow the instructions I wrote down.
For other OS’es there are ways to do this, like setting the LD_LIBRARY_PATH for example (you'll have to google this)

Feedback is welcome so I can improve the installation instructions :)
