- 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
