The program needs to be compiled with the following option selected,

  Project Settings, C/C++,Category: Customize, Disable Language Extensions.

Without this option I get the same errors as above.  I will add that
to the notes.

However, I found that if I had compiled the program once with the
wrong setting then changing it had no effect (even after selecting
'Build - Clean').  I had to create a NEW workspace with the correct
setting first, and then it compile it.  Then it worked. Maybe it is
something to do with 'precompiled headers'.

The interface to the matrix/vector view functions has changed between
version 0.8 and 0.9, see the manual for details.

Thanks for reporting that I have uploaded a new rpm file to
sources.redhat.com created as root, so it should install properly.
