Error Code 001

Overview

This error occurs when the compiler encounters an identifier (e.g., variable, function) that hasn’t been defined or imported in the current scope.

Details

  • Common Causes:

    • Misspelling a variable or function name.
    • Forgetting to declare the identifier before use.
    • Missing an import statement for external modules.

  • Example:

void main() {
    x = 5; // Error: undefined identifier `x`
}
  • Solution: Declare or define the missing identifier:
void main() {
    int x = 5;
}

Or ensure the correct module is imported:

import mymodule;

void main() {
    mymodule.function();
}
