Use of library in STM IDE. How to consume cpp code? The library compiles if I have classes but as soon as I try to reference from main.c for example it even does not recognize instruction new, for example

Your problem description seems to miss some details.

The more detailed your description, the better the answers will match.

C and C++ calls are not directly compatible, cf. name-mangling.

You would need to declare every C++ function callable from C as "extern "C" ".

Well,

I started from a project of a STM Workshop.

Then I added a second project that is of type static library and for the same Discovery Board.

I started typing some C++ classes in the library and everything compiles. Then I added

a reference to the Library project and from the main project I can see the types of the library.

Then i added an Initialize.h file in which i declared a function in Initialize.cpp with decoration extern "C"

but inside this function I cannot type any C++ code.

Attached is the project , If you could please take a look.

I cannot understand, I used the same procedure used fro touchgfx and they are cpp code. I think somehow it does not recognize cpp in the library

when imported but the library is created in C++. I checked the option when i created.

Sorry, but I don't use Cube/HAL or STM Workshop. Nor touchgfx.

Does this mean, you want to use a C++ library from a C code application ?

Then why not sticking to C++ ?

And if both are C++, you do not need to restrict the library to the C linker capabilitites.

[FMarr.2]

Possible.

Not all the code of the project is C++, some code especially drivers are in C++.

This is not a problem

In CubeIDE, right click on the project and select "convert to C++"
