Structure Packing using __attribute__((__packed__)) in GNU GCC
Try: struct __attribute__((__packed__)) structure2 { // ^^^^^ int id1; char name; int id2; char c; float percentage; }; It doesn''t make sense to pack one single field. As you said it yourself, padding is about the relationship between fields, so the attribute belongs on the struct itself, not on its fields.
