Hi Matt,

since a while MITK Core is warning free. In order that this doesn't change we 
decided to treat each new warning as error. Since you are using an rather old 
version of gcc this "no newline at end of file" warning occurs. (Which is now 
treated as error.) If I am informed correctly this warning doesn't occur with 
gcc >= 4.3.

You could now use a newer compiler or you have to remove the WError flag 
manually for this specific build.

Regards
Andreas

Hi there,

I am doing a build of a recent version of MITK, and at one point there are 
warnings:

But then, they switch to errors and the build stops:

This is occuring once I merged MITK version 53aba30c0c into our MITK fork, on 
Slackware, running gcc 4.1.2.

Any ideas?

Thanks
