template with static member

[Patrick McConnell]

The following code gives the link error:

[Linker Error] Unresolved external 'C1<int>::f()' referenced from D:\PROGRAM
FILES\BORLAND\C BUILDER5\PROJEC TS\MAIN.OBJ

Using Borland CBuilder5. If i define the body of the function f in the
header file1.h, it links ok. I believe this is normal language behaviour
because all the ATL libs are defined in the headers. But is there another
way to do it so i can define my functions in the cpp file?

file1.h:
/////////////////////////////////
template<class T>
class C1
{
public:
static void f();
};
/////////////////////////////////

file1.cpp:
/////////////////////////////////
template<class T>
void C1<T>::f()
{
}
/////////////////////////////////

main.cpp:
/////////////////////////////////
#include "file1.h"

int main(int argc, char* argv[])
{
C1::f();
return 0;
}

No, templates must go in the header file.

There is an export keyword that is supposed to handle this but

a) its contrversial
b) only one compiler supports it (and its not borland)

At least two :). EDG has its own back-ends too.
