BUG REPORT:
Gnu C version 2.0 compiled etc and linked this program OK (as 'gcc t$$$.cc'):-
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
class scubadiver_catcher{public:
int i,j,k,l;
void call_into_action(char*s){j=strlen(s);};
void scubadiver_catcher::radio_for(char*s){k=strlen(s);};};
scubadiver_catcher Aphanistor;
main(){
Aphanistor.call_into_action("5 seen at Long Cove");
Aphanistor.radio_for("12 in 2 boats offshore from Black Rock Head");}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
But if I compiled it in 2 parts, as 'gcc t$$$1.cc t$$$2.cc':-
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<<file t$$$1.cc>>
class scubadiver_catcher{public:
int i,j,k,l;
void call_into_action(char*s){j=strlen(s);};
void scubadiver_catcher::radio_for(char*s){k=strlen(s);};};
void dummy(){}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<<file t$$$2.cc>>
class scubadiver_catcher{public:
int i,j,k,l;
void call_into_action(char*s);
void scubadiver_catcher::radio_for(char*s);};
scubadiver_catcher Aphanistor;
main(){
Aphanistor.call_into_action("5 seen at Long Cove");
Aphanistor.radio_for("12 in 2 boats offshore from Black Rock Head");}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
the linker said this:-
t$$$2.o: Undefined symbol scubadiver_catcher::call_into_action(char *) reference
d from text symbol
Note that '_call_into_action__18scubadiver_catcherPc:' is not declared as global
in assembler file t$$$1.s as produced bu Gnu C++ version 2.0 .
This bug was not present in the last version of Gnu C which I had (1.39?).
