Why do I get “warning: missing initializer for member”? [-Wmissing-field-initializers]

Question

I\'m wondering why I am getting a warning about initialization in one case, but not the other. The code is in a C++ source file, and using GCC 4.7 with -std=c++11

Answer 1

The only way to prevent that warning ( or error, if you or your organization is treating warning as error (-Werror option)) is to memset() it to init value. For example:

#include 
#include 

typedef struct {
    int a;
    int b;
    char c[12];
} testtype_t;

int main(int argc, char* argv[]) {
    testtype_t type1;

    memset(&type1, 0, sizeof(testtype_t));

    printf("%d, %s, %d\n", argc, argv[0], type1.a);
    return 0;
}

Not very clean, however, seems like that for GCC maintainers, there is only one way to initialize a struct and code beauty is not on top of their list.
