This error indicate that your code, usually from C family language, has imported a header but has not yet been linked to it?s implementation.
For example there is a header SimpleMath.h
// SimpleMath.hint divide_by_zero(int i);
Then we import it in main.c
// main.c#include “SimpleMath.h”int main() { int result = divide_by_zero(100); printf(“Result is %d”, result);}
When we compile it without implementation of SimpleMath.h then we we?ll get ld: symbol not … (bla-bla-bla)
The solution is to compile it with SimpleMath.c
clang main.c SimpleMath.c -o program
Or to link it with system implementation if there any.
clang main.c -LSimpleMath -o program
Fixed? Not yet. You?ll want to read more about C language then.
Oh yes, our SimpleMath.c implementation is
// SimpleMath.c#include “SimpleMath.h”int divide_by_zero(int i) { exit(1);}
Happy fixing error!
