when run build on project the qcreator hangs

I create black Qt4 console application. into main.cpp add lines
struct ItemPoint {
int abs0_or_Relativ_1;
int k;
qreal x,y;
qreal i,j;
};

struct Item {
struct ItemPoint points[];
};

struct Items {
struct Item items[];
};

struct Items items[]=
{
NULL,
};

When I start Build into the compile outpiut write some many times
main.cpp:23:warning:missing braces around initializer for Item[0]

and qtcreator hangs and I have to kill it
