Hello Ides,
If you are using the current cvs repository version of blitz, then you need
to change your cast notation slightly. Using the "new" expression template
machinery, I made what I hope is an improvement in notation. Instead of
cast(foo, int())
you can now say simply
cast<int>(foo)
I think this style is more similar to the C++ cast functions. Try making
the corresponding change in your code and let me know if you still have a
problem. I'm sorry that the old blitz documentation has not been updated.
Regards, Julian C.
