hi all,
i'm trying to compile simple native application under Android platform
and got problem with linker (looks like linker or linker scripts bug)
my simple program:
class C
{
static int m;
public:
static void f() { m = 0; }
};
int main(int, char**)
{
C::f();
return 0;
}
compilation commands:

linker output and error message:
main2.o: In function `C::f()':
main2.cpp:(.gnu.linkonce.t._ZN1C1fEv+0x64): undefined reference to
`C::m'
collect2: ld returned 1 exit status
Maybe I use wrong ldscripts? Have somebody any suggestions?
Thanks for advice.
