You (probably) have the wrong compiler. And definitely have the wrong 
include files. You might note the complaint about /usr/include/dirent.h, 
but /usr/include should not show up in your build since everything 
should be coming from your VxWorks installation.

I'm not sure what your cross-compiler is called, but plain "g++" is 
probably not the right thing. For my PPC targets, the compiler is called 
"c++ppc". The implicit use of /usr/include in your search path is 
probably coming from /usr/bin/g++.
