CubeIDE: Imported Eclipse 'C' Project incorrectly defines __cplusplus

[Andrew Neil]

STM32 CubeIDE v1.5.1; Build: 9029_20201210_1234 (UTC)

The same Eclipse Project as:

https://community.st.com/s/question/0D53W00000Y2lIsSAJ/cant-usecreate-debug-config-for-oss7-stack

It is a 'C' Project, but the CubeIDE defines __cplusplus:

 

Which, as you can see, messes-up the codes checks to see if C++ is being used!

If I manually delete that definition, all is fine.

The problem does not happen when opening the project in a "normal" Eclipse Neon 3.

So why is CubeIDE adding this?

[UFAnders]

I'm sorry to report that the "little stunt" to expose the MCU listing in IDE v1.7.0 no longer works. So, right now I cannot debug my project.

Can we please revisit this ASAP? Thanks!

[Andrew Neil]

When you say, "no longer" - does that mean it was previously working for you?

Las time I tried on v1.7.0 (probably a month or so ago), it was still working.

Have you recently done an update? Are you sure you're still on 1.7.0?

[UFAnders]

Ohhh I'm on 1.8.0!

 

Any ideas?

[Andrew Neil]

"Any ideas?"

I think we'll have to as @mattias norlander​ ...

If you have a 1.7.0 project to which the "little stunt" has been applied, does that then work when opened in 1.8.0 ?

[UFAnders]

Yes, I can debug my 1.7.0 Makefile project just fine.

[Andrew Neil]

Just to be clear: That's a project created in 1.7.0, and then opened in 1.8.0 ?

[UFAnders]

Yes, I had created this Makefile project in 1.7.0, and it still works in 1.8.0. Appreciate the help!

[UFAnders]

I finally got things working by deleting:

• .settings/*
• *.project
• *.cproject

So, I think the problem lies in there somewhere.

[Andrew Neil]

Hmm ... the .cproject and .project are the Project - so does that mean you had to re-create the Project from scratch?

[UFAnders]

Yes, I had to re-create the projects from scratch. I seem to be posting half-answers, haha sorry about that.

I thought it had been a workspace issue because I had deleted and re-created the project several times to no avail. I'm thinking maybe the project files aren't being cleared/deleted when they're deleted from the IDE project tree?
