I want to create a global variable that can be used in all ScreenViews in CubeIDE.

What I have tried:

I have tried to:

create this variable in Screen5View in public: in hpp
create a new header file, name it globals.h and create a variable there

The error is always the same.

"fatal error: globals.h: No such file or directory" or that the int was not defined.

The error message is pretty clear:

Error

globals.h: No such file or directory

And it means what it says - the file globals.h is not in any location that the compiler is checking.
Start by finding the file, and compare its location with the rest of your source code. If it's not in the same folder, you need to add that location to

Solution 2

I have located where all of my other header files were.
-gui
-include
-gui
-include
-common
and made a notepad and wrote the code there. Than I included the following line in header file of screen5view and screen2View where I wanted the variable to be used

#include <gui common="" globals.hpp="">

Don't do that. Add the path to your project headers files to the project settings as I said in my reply.
If you go down your route, then the next project you create will generate it's own globals.h file which you will need to overwrite this projects with - so this project will then fail to build when you need to make changes later.
