It happens when correct libraries are not present on the link line.
One way to arrange for that is to link with 'gcc', anouther is to
link with 'g++ -nodefaultlibs'

I think you don't understand how linking works, and that your
"size constaints" argument is bogus: if you have a successful link,
removing -nodefaultlibs from the link line should have almost
no effect on the final exe size.

Sure: just add the libraries that you removed with '-nodefaultlibs'
back on to the command line :)

FYI, __cxa_pure_virtual is in libstdc++.{a,so}
