Have a look at the C++ example in the rtlinux distribution. What yoe REALLY
have to do with c++ is:
int init_module(void)
{
__do_global_ctors_aux();
...
}
void cleanup_module(void)
{
...
__do_global_dtors_aux();
};
This should initialize your static classes (unless you don't forget to link
the CRTs).

look for the rt_math module there.
