c++ - expected primary-expression before ‘>’ token

I have a code like:

class Client2ServerProtocol {
};
class ProtocolHelper {
public:
    template
    int GetProtocolId() {
        return -1;
    }
};
template<> inline int
ProtocolHelper::GetProtocolId() {
    return 1;
}
template
class Dispatcher {
public:
    template
    void Subscribe(int msgId) {
        int protoId = helper.GetProtocolId();
        printf("Subscribe protoId %d, msgId %d", protoId, msgId);
    }
    PROTOCOL_HELPER helper;
};
int main() {
    Dispatcher dispatcher;
    dispatcher.Subscribe(1);
    return 0;
}

It compiles successfully (and works) under MSVC, but gcc is complaining about invalid syntax:

test.cc:23:56: error: expected primary-expression before ‘>’ token
int protoId = helper.GetProtocolId();

test.cc:23:58: error: expected primary-expression before ‘)’ token

What i'm doing wrong?
int protoId = helper.GetProtocolId();
