	Code compiles in Arduino but gives error in Visual studio. Using Ardunio 1.8.5, Vmicro version 1711.19.0 testbug.ino: 5:11: error: variable or field 'test' declared void void test(b bstruct) Error compiling project sources testbug.ino: 5:11: error: 'b' was not declared in this scope Build failed for project 'testbug' Any ideas? code is below. struct a { int number; }; struct b { a astruct; }; void test(b bstruct) { }; void setup(){ }; void loop(){ };

	if you add the prototype yourself then using your own types in the same file (as opposed to .h) is more controllable. In background, arduino ide will add prototypes before the first function, visual micro before first code. Both can be wrong depending on the code, so it's safer to add your own like this... Code (C++) //types // struct a { int number; }; struct b { a astruct; }; // add a method prototype with the same signature; after types have been created but before the actual method // void test(b bstruct); //code // void test(b bstruct) { }; void setup(){ }; void loop(){ };
