Hello,
this is my first posting in the usenet so please sorry for choosing the wrong groups ..... but I need help !!!
I have a problem with the GNU C++ V2.1 Compiler on my SPARCstation SLC, using sunos4.1.1 !!!
The problem is the following:
FILE1: foo_test.cc
#include "foo.h"
main() {
Array<int> ALF;
}
FILE2: foo.h
template <class Typ>
class Array {
public: Array() {Init();}
private: void Init();
};
FILE3: foo.cc
#include "foo.h"
template <class Typ> void
Array<Typ>::Init() {
}
COMMANDS:
g++ -c foo.cc
g++ foo_test.cc foo.o
This results in the following linker error:
ld: Undifined symbol
_Init__t5Array1Zi
collect: /usr/bin/ld returned 2 exit status
But if I put all 3 files in one, it works.
It seems, that the linker has a problem with the template class.
Can anybody explain what I am doing wrong or if something is not
installed correctly.
Thanks in advance
Hans-Juergen
