Hi cspl,
Did you make a "cvs update" ?
or just downloaded the examples directories ?
From the error message that you posted, it looks
like you have two unsynchronized versions of
the ImageIOBase and RawImageIO classes.
RawImageIO derives from ImageIOBase
ImageIOBase has a pure virtual method "Write()",
that has to be overloaded by any writer. The signature
of "Write()" in your version of RawImageIO doesn't match
the signature of "Write()" on your version of ImageIOBase.
You have:
void ImageIOBase::Write( void * );
void RawImageIO::Write( const void * );
We have put a lot of effort on making ITK const-correct,
the version that you have of ImageIOBase should be
relatively old.
All the ImageIO objects implementing the reading and
writing of specific file formats derive from ImageIOBase
and therefore have to implement the "Write()" method.
(among others...)
http://www.itk.org/Insight/Doxygen/html/classitk_1_1ImageIOBase.html
Please make sure that you have a consistent checkout of ITK.
Let us know if you still find any problems after updating
your cvs checkout.
Thanks
Luis
PS: If you would like to have some guidelines about how
to use cvs we will be happy to point you to some URLs.
