Hi,

I have a problem in compiling 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?

Error:
