Need to add a C++ file to a C project

Postby MichaelDennis » Mon Mar 04, 2019 2:30 am

I'd like to have both C and C++ files in the same TrueSTUDIO project.

I'm using an STMicroelectronics C based sample project, and it's quite complex, so I want to keep the project and add my C++ file to it. (In other words, I don't want to create a new project.)

When I add a C++ file to the project and do a build, the C++ file is ignored.

As a side note, I notice that the "Build Selected" files option (when I right click) is grayed out for the C++ file. (I have this feature enabled in my system, and it works with the C files in the project, but not with C++ files.)

Thank you for your help.

Hello,

This maybe related in how the project was made since it's a C project verse a C++ project.

You have to Convert an existing project to a embedded C/C++ Project.

Close the project in project explorer. Right Click on the project you want to convert, use "New -> Convert to a C/C++ Project (adds C/C++ nature).

You can check if it has worked by having a look into the compiler settings. After the convert procedure a new chapter with c++ Compiler settings will appear in addition to assambler, c-compiler, linker, ...

best regards
