Introduction

If you are a programmer, you may have come across an error message like "error: array type has incomplete element type" while compiling your code using GCC. This error message can be frustrating as it can be difficult to figure out the cause. In this article, we will discuss the reasons for this error and provide easy fixes to resolve it.

The Cause of GCC Array Incomplete Element Type Error

The GCC Array Incomplete Element Type error occurs when you are trying to compile code that declares an array with an incomplete element type. An element type is considered incomplete if it has been declared but not defined. This can occur when you use a forward declaration of a struct or union as the element type of an array.

Easy Fixes for GCC Array Incomplete Element Type Error

There are a few easy fixes for this error. One way to resolve this error is to include the header file that defines the struct or union. This will provide the definition of the element type. Another way to fix this error is to move the declaration of the struct or union above the declaration of the array. This will ensure that the element type is defined before it is used in the array declaration.

Example

#include <stdio.h>
struct MyStruct; // forward declaration of struct MyStruct
int main(void) {
    struct MyStruct myArray[10]; // GCC Array Incomplete Element Type error
    return 0;
}
struct MyStruct {
    int x;
}; // definition of struct MyStruct

In this example, the struct MyStruct is forward declared before the array declaration. This will result in the GCC Array Incomplete Element Type error. To fix this error, we can move the definition of the struct MyStruct above the array declaration.

#include <stdio.h>
struct MyStruct {
    int x;
}; // definition of struct MyStruct
int main(void) {
    struct MyStruct myArray[10]; // no more GCC Array Incomplete Element Type error
    return 0;
}

By moving the definition of struct MyStruct above the array declaration, we have resolved the GCC Array Incomplete Element Type error.

Conclusion

The GCC Array Incomplete Element Type error can be frustrating to deal with, but it is usually easy to fix. By including the header file that defines the element type or moving the declaration of the element type above the array declaration, you can resolve this error and get back to coding.
