If you add a #include "foo.C" in foo.h, it will work.

You will need to protect both foo.C and foo.h from multiple inclusion
ie:
foo.C:
#ifndef __FOO_C
#define __FOO_C
#include "foo.h"

int main() {
    foo<int> z;

    z.hmm();
}
#endif /*__FOO_C*/

foo.h:
#ifndef __FOO_H
#define __FOO_H
template <class T>
class foo {
public:
    int hmm();
};

#include "foo.C"
#endif /*__FOO_H*/


This is because GCC needs visibility of template *implementations* from
wherever they are instantiated.

Hope this helps,
Rusty.
