hi
this is my code under redhat linux 8.0.
//a.h
#ifndef ah
#define ah
int i;
void add();
#endif
//a.cpp
#include "a.h"
void add(){
i++;
}
//c.cpp
#include "a.h"
int main(){
i = 100;
add();
return 0;
}
g++ -c a.cpp success
g++ c.cpp a.o
error: a.o(.bss+0x0): multiple definition of 'i'
/tmp/cc0q7tmK.o(.bss+0x0): first defined here
collect2: ld returned 1 exit status.
