Posted on May 17, 2011 at 12:43Hi,
I have a problem in compiling in gcc long long int data type.
I have linker error when I declare long long int as global variable and want to divide by another long long int variable.
example that generate error:
long long int a=1;
long long int b=1;
long long int c=1;
void Fun1(void){ //Fun1 is called form another file
a=1;
}
void Fun2(void){
a=b/c;
}
example that not generate error:
long long int a=1;
long long int b=1;
long long int c=1;
void Fun1(void){
a=1;
}
void Fun2(void){
Fun1();
a=b/c;
}
Can somebodey explain this?
