Access Component Functions in another class

[sheershak-agarwal]

Hello,

I want basic inheritance functionality. I have a Class for the state Machine and I want to call the gpios, uart write etc functions of the ComponentImpl in the state machine class(GpsSM).

I have GpsComponentImpl.hpp, GpsComponentImpl.cpp and GpsSM.h in the same folder.

I am adding this in my GpsSM.h
#include "App/Common/StateMachine.h"
#include "GpsComponentImpl.hpp"

class GpsSM : public StateMachine, public App:GpsComponentImpl {};

but I get an error In file included from /home/sheershak/Desktop/F-Prime-Debug/App/Gps/GpsComponentImpl.hpp:17:0,
App/Gps/CMakeFiles/App_Gps.dir/build.make:103: recipe for target 'App/Gps/CMakeFiles/App_Gps.dir/GpsComponentImpl.cpp.obj' failed
from /home/sheershak/Desktop/F-Prime-Debug/App/Gps/GpsComponentImpl.cpp:14:
/home/sheershak/Desktop/F-Prime-Debug/App/Gps/GpsSM.h:17:1: error: expected class-name before ‘{’ token
{
^

I read some other links regarding the issue but couldn't find solution. I also see there is GpsComponentBase. I tried inheriting that too but same error. Also I am creating an object of GpsSM in GpsComponentImpl.hpp with private member.

That usually means that the compiler can't find the base class types. Double-check your spelling including any namespaces.

I think you need "::" for your namespace.

public App:GpsComponentImpl {}

Needs to be

public App::GpsComponentImpl {}

Yes, there was a problem in the logic. I was trying to create an object GpsSM in GpsComponentImpl class and trying to inherit GpsComponentImpl in the GpsSM. I got rid of the GpsSM and added the logic in Impl class. That solves my issue.
Thanks
