this is my sample files
test.h
#ifndef _TEST
#define _TEST
template <class T>
class res_mgr
{
public:
res_mgr();
~res_mgr();
int load_all();
};
#endif
test.cpp
#include "test.h"
template<class T>
res_mgr<T>::res_mgr()
{
}
template<class T>
res_mgr<T>::~res_mgr()
{
}
template<class T>
int res_mgr<T>::load_all()
{
return 0;
}
main.cpp
#include "test.h"
int main(int argc, char** argv)
{
res_mgr<int> mgr;
return 0;
}
I compiled the project, and I got something like these:
[color="#0000FF"]--------------------Configuration: cpp_test - Win32 Debug--------------------

[color="#000000"]EDIT:
[color="#000000"]I've googled to look up some c++ template tutorials so I can compare my code with theirs, but it seems that my code is just fine. I don't understand what caused the errors, can you guys shed some lights on this?
Btw I use the oldie MSVC6.0
