Ah, you've told bjam to use the gcc C compiler: and while that will 
correctly compile C++ code, when used as a linker it doesn't know anything 
about the C++ runtime libraries required, and hence the errors.  Use the g++ 
variant in /home/rich/gumstix/gumstixLatest/build_arm_nofpu/staging_dir/bin/ 
if you have one, if you don't then I'm at a loss, consult the docs for the 
ambedded linux version to see how you're supposed to link C++ code I guess ! 
:-)

HTH, John.
