Question

I have a structure that contains an arrays of another structure, it looks something like this:

 typedef struct bla Bla; typedef struct point Point;  struct point {     int x, y; };  struct bla {     int another_var;     Point *foo; }; 

I now want to initialize them in the global scope. They are intended as description of a module. I tried to do that with c99 compound literals, but the compiler (gcc) didn’t like it:

 Bla test = {     0, (Point[]) {(Point){1, 2}, (Point){3, 4}} }; 

I get the following errors:

 error: initializer element is not constant error: (near initialization for 'test') 

Since I don’t need to modify it I can put as many ‘const’ in it as necessary. Is there a way to compile it?

You don’t need a compound literal for each element, just create a single compound literal array:

Bla test = {     0, (Point[]) {{1, 2}, {3, 4}} }; 

Make sure you compile with -std=c99.
