Question

I have a function that takes a struct, and I’m trying to store its variables in array:

int detect_prm(Param prm) {   int prm_arr[] = {prm.field1, prm.field2, prm.field3};    return 0; } 

But with gcc -Wall -ansi -pedantic-errors -Werror I get the following error:

initializer element is not computable at load time

It looks fine to me, what’s wrong?

Answer 1

This is illegal in C. Initializer lists must be constant compile time expressions. Do the following instead:

int prm_arr[3];  prm_arr[0] = prm.field1; prm_arr[1] = prm.field2; prm_arr[2] = prm.field3;
