We have compiled this tip for developers who work with the Workbench for STM and want to compile their project with C++.
Generate The C code in the STM32CubeMX according to the hardware configuration for the System Workbench for STM32. C++ code generation is not supported here.
Image 1: STM32CubeMX Code Generation – Project Settings
Open the created project with the System Workbench for STM32 (e.g. by double-clicking on the .project (File in the generated project folder).
Create The project. Error messages may still occur.
Convert Convert the C project to a C++ project using the System Workbench for STM32; use the context menu to do this.

Check The C++ project settings (normally nothing needs to be changed). The path settings are automatically copied from the previous C settings.

Name in the project browser main.c in main.cpp um.

Add the following lines in main.h in addition:
…
#ifndef __MAIN_H
#define __MAIN_H
#ifdef __cplusplus
external ""C" {
#endif
…
#ifdef __cplusplus }
#endif
#endif /* __MAIN_H */

Add the following lines in main.cpp in addition:
… /* Private function prototypes -----------------------------------------------*/
#ifdef __cplusplus
external ""C" {
#endif
void SystemClock_Config(void);
static void MX_GPIO_Init(void);
#ifdef __cplusplus }
#endif
…

Clean the The project and its mistakes.
Create The project; no more errors should occur.
However, any potential warning signs should still be checked.
