Error “initializer element is not constant” when trying to initialize variable with const

Question

I get an error on line 6 (initialize my_foo to foo_init) of the following program and I\'m not sure I understand why.

typedef struct foo_t {
    int a, b, c;

Just for illustration by compare and contrast The code is from http://www.geeksforgeeks.org/g-fact-80/ /The code fails in gcc and passes in g++/

#include
int initializer(void)
{
    return 50;
}

int main()
{
    int j;
    for (j=0;j<10;j++)
    {
        static int i = initializer();
        /*The variable i is only initialized to one*/
        printf(" value of i = %d ", i);
        i++;
    }
    return 0;
}
