Hello!

To compile C++ source under QNX 4 you have to install Watcom C++ Compiler. It is separate module with its own license.

As for your Open Watcom errors. Personally I did not use Open Watcom under QNX. I guess it is better to contact to Open 
Watcom project maintainer. But it seems that streambu.h should be streambuf.h.

Respectfully,
Oleg
