undefined reference to '__cxa_pure_virtual' while using -nodefaultlibs

[Hansen]

Hi

I'm compiling a C++ program to an ARM7 where I've used pure virtual 
functions. But when I link, I get the undefined reference to 
'__cxa_pure_virtual'. As far as I've understod, this happens when using g++ 
for compiling and gcc for linking, but I'm using g++ in both cases.
It seems as if I can remove the problem if I remove the 
option -nodefaultlibs from my linker options, but I doesn't want to do that, 
due to size constraints. Is there anyhow I can keep the -nodefaultlibs and 
get rid of the undefined reference to '__cxa_pure_virtual' ?

Best Regards
