Impossible to rename main.c into main.cpp in sample code?

Hi,

I'm using the sample HID_Standalone (USB_Host) for the board NUCLEO-H723ZG. I tried to rename the file main.c into main.cpp to force compilation with g++ instead of gcc. This worked fine with an Hello World I studied before.
Unfortunately, a really weird behaviour appears. If I rename the file with right click -> rename, the file appears renamed on the IDE but the actual file on the filesystem stays main.c. If I open with right click->show in->system explorer it's still main.c. If I run the build project command it still looks for main.c. If I rename the file on the system explorer it says that file main.c is not found. If I rename subdir.mk in the core folder another one is generated and it still contains main.c.

How to rename correctly the file? Is this the expected behaviour?

Right click rename should be working. Works for me.

Could create a new file and copy over the contents and delete the old file. Convert the project to C++ so it looks for those sources.

Hi TDK,

apparently the files on this example, as shown on the eclipse/Cube IDE, are links. if I right click->show in->properties I can see the various parameters associated. It appears that when you rename them, the original file is not renamed, (but the link is). As a workaround, I removed the link main.c from the left panel on Cube, renamed it on the system explorer and then dragged/dropped the renamed file on the folder back on the left panel of Cube. At that point a pop up menu opens with some options for the new link.
Once that was done, I converted the project to C++, and now trying to figure out some compilation errors that arise. Thanks for the help.

This can be if main.c in the eclipse project is a "linked file".  In this case the .project contains two different names, one shown in the project explorer tree and the real one. Example:

 

<linkedResources>
   <link>
     <name>Src/MAIN.CPP</name>
     <type>1</type>
     <locationURI>PARENT-2-PROJECT_LOC/Src/main.c</locationURI>
   </link>
...............
</linkedResources>

 

Very intuitive, duh.

It's a sarcasm... Is it?

(Obviously always "very intuitive" :grinning_face_with_sweat:)
