Error Code 011

Overview

This error occurs when the compiler cannot find a module specified in an import statement. It typically results from incorrect module names, missing files, or improper project configuration.

Details

  • Common Causes:

    • Specifying a module that doesn’t exist in the source directories.
    • Typographical errors in the module name.
    • Missing paths or misconfigured imports in the project setup.

  • Example:

import nonexistentmodule; // Error: module `nonexistentmodule` not found

void main() {
    writeln("Hello, World!");
}
  • Solution:

    • Ensure the module exists in the project directory structure:

      // Correct module declaration in a file named mymodule.d
module mymodule;

void myFunction() {
    writeln("This is my module!");
}
      • Import it properly: 
        import mymodule;

void main() {
    myFunction();
}

    • Add the correct source paths to your project configuration:

      dmd -I./src myprogram.d

    • Double-check for typographical errors in the import statement.
