This is a mailing list on how to use the debian operating system, so it isn't 
a particularly good choice.  You'd have been better off on a specialist 
programming mailing list for, or even debian-devel.

Firstly, formatting would make this much easier to read. 

class t {
  public:
    static char *p;
};

char t::*p;

main() {
  t k;
  k.p="";
}

There is a lot of personal preference involved, but this is much easier to 
read than the one you wrote.

Now, the problem is with the line char t::*p

This says to use the default initialiser for the character pointed to by t's 
member named p.  I'm not sure this is valid even if t::p had been declared, 
but it isn't valid if it hasn't.

changing it to
char * t::p should work.
