sounds like a problem in your path... are you sure your cross-gcc isn't 
installed first in you path ?

I previously tried to have C++ support for vxworks... the problem is:
c++ includes provided with vxworks (like list and vector...) are old and 
buggy (some are 10years old) and are not compatible with the c++ 
standard. So g++ reject them.
So you might want to delete them and use those provided bu libstdc++ but 
you'll have to port this lib to vxworks and here are some real 
issues....for example thread definition are incompatible....
It might be an interesting job but my customer didn't want to pay, so I 
stopped working on it...
