Hi,

I have class cTest, its definition is in one file and declaration in another
---test.h---
class cTest { public : void fun(); };
---test.cc---
void cTest::fun() {  }
And this is ok, I can use it :
---main.cc---
#include "test.h"
int main() { cTest t; t.fun(); return 0; }

But after changing class to template I cant link program :

---test.h---
template <class typ> class cTest { public : void fun(); };
---test.cc---
template <clas typ> void cTest<typ>::fun() {  }
And this is ok, I can use it :
---main.cc---
#include "test.h"
int main() { cTest<int> t; t.fun(); return 0; }

This generates error at link-time, that linker can't find body of void
cTest<int>::fun()...

How to solve this problem ? I must use .cc + .h (not single .cc) because I
want to use this template class in many parts of project...

Thanks in advice :)
