Hi!
I am using the following:
IBM RS 6000 running AIX 3.2
g++ I believe version gcc-2.2.2 (it knows about templates)
----------------------------------------------------------------------------
The following program runs without any problems:
//template<class T> int myfunc(T x);
template<class T> int myfunc(T x) {
return 2;
}
int myfunc2(int x);
int myfunc2(int x) {
return 2;
}
main() {
myfunc(3);
myfunc2(0);
}
----------------------------------------------------------------------------
Now uncomment the first line to create a forward declaration, I get the
following problem:
bart /u/w2martin/c : g++ g++test.C
0706-317 ERROR: Unresolved or undefined symbols detected:
Symbols in error (followed by references) are
dumped to the load map.
.myfunc__Fi
collect: /bin/ld returned 8 exit status
----------------------------------------------------------------------------
What is wrong? The IBM xlC C++ compiler accepts the same code, but I want
to use g++ since we have it at MIT.
If you could help me, write to w2martin@watson.ibm.com OR to
martins@athena.mit.edu
Thanks,
Martin Szummer
