c++ class memory consumption

Hello,

I am stuck at the compiler options. Where can i set them in the NIOS SBT IDE?

This is just to test, if I can use c++ the way I'd like to.

I have a project, momentary written in C which contains a few functions which manage UART communication, CAN communication, writing into the internal flash of the fpga and so on and i thought about rewritting the code in c++ because i like the idea about creating classes and defining objects.

I would probably be able to write the code without any need for a custom destructor, but just in case I want to be able to use it without the massive memory allocation which occurs at the moment.
