SWV ITM (printf) is not working with main.cpp(c++) but with main.c it works like a charm.

Okay basically i have two question,

[1]

SWV ITM (printf) is not working with main.cpp(c++) but with main.c it works as a charm. The culprit seems to be is main.cpp but i have no idea how to make it work there.

[2]

 The project is converted to C++ even though it produces main.c files instead of main.cpp. So i have to manually rename it to main.cpp . When ever i make any changes to .ioc the cubeMx inside of the cubeIDE produces the main.c instead of a c++. Is there any way to automatically generate source files in cpp extension because manually renaming it often leads to human error. Thank you.

If you just leave the generated main.c as is, both self-inflicted issues would disappear.

Thats very basic, but couldn't do it as the project has a library that was written in c++.

Sure you can. You could, for example, create something like "appmain.cpp" with a function "appmain(void)". In appmain.h you provide the function prototype:

#ifdef __cplusplus
   extern "C" {
#endif
 
void appmain( void );
 
#ifdef __cpluscplus
   }
#endif

Then from main(), call your appmain() to then call C++ functions, instantiate class instances, etc.
