VS Code - use g++ for main.c

[truland]

Hi,

I wanted to give Visual Studio Code a try and converted an existing STM32CubeIDE project. In the original project, the main.c (in Core/Src directory) file was compiled using g++, since it has some C++ content. However, VS Code invokes gcc, and therefore, build is not successful. How can I change this?

One other thing, I noticed when converting the project, all source files are copied to the new location, but the .ioc file is not. Is this intended behaviour?

did you try renaming main.c to main.cpp? that should trigger the c++ compiler.

Well, sure if I rename the file ist will work, however if I change something in CubeMX, a new main.c will be generated, and the two files will have to be merged manually. So I think this is not a good long-term solution

[svogl]

well, if you want to stick to cubemx, then why not move your code to a separate cpp file & place a simple function call the main.c user section?

since it has some C++ content

 

Why did you put C++ code in a C-file?

Just create a separate cpp entry function you call from main.c.

Yes, I know that’s a clean solution, thank you. I was just wondering that the CudeIDE’s project setting to use g++ for compiling main.c was abandoned when migrating the project to VS code.

Apart from that, I’m quite sure it’s possible to change the behaviour with CMake, I just don’t know how to do this. 

Anyway, I’m seeing my problem as resolved now.

Great! So now please mark the solution on the post which provided the resolution - not this one!
