Hi carol,

It is the startup crt0.o problem.

It should be easier if you work on Linux and follow my buildroot guide,

http://forum.niosforum.com/forum/index.php?showtopic=3174 (http://forum.niosforum.com/forum/index.php?showtopic=3174)

The step8 in port#1 tells you how to compile and run a simple program on uClinux.

About C++, you can not use nios2-elf's libstdc++, it is bond to newlib.

On uClinux, you should need that which is bond to uClibc.

The libstdc++ which we built with uClibc still have problems, it compiled and linked, but crashed when running on uClinux. I am not a C++ user, and I can't resolve the problems without help from C++ user.
