non-trivial designated initializers not supported

Posted 2022-12-30 奇妙之二进制

the order of initialization needs to be in the exact order of declaration.

typedef struct FOO

    int a;
    int b;
    int c;
FOO;

FOO foo = .a = 1, .b = 2; // OK
FOO foo1 = .a = 1; // OK
FOO foo2 = .b = 2, .a = 1; // Error sorry, unimplemented: non-trivial designated initializers not supported
FOO foo3 = .a = 1, .c = 2; // Error sorry, unimplemented: non-trivial designated initializers not supported

解释：
I understand that this means that the compiler has no support for name-oriented, out-of-order, member initialization.

Need to initialize the struct in the old fashioned way. I keep the variable names for clarity, but I have to initialize them in order, and not skip a variable.

I can stop the initialization at any variable, but can’t initialize variables that come of that.

解决方法：
Assign to .name=value fields
Assign in the order they where declared
Include all fields in the assigment
