CubeIDE cannot find header files after import

[rcard]

This is an issue i currently have with two differents project. After importing an error free project, the IDE have issue linking included files.

When building i have "fatal error: FLASH_G0.h: No such file or directory" on the #include "foo.h" line, as if the .h weren't there.

But the file are there, and when i press F3 over the foo.h, the IDE open foo.h without any issue, proving the files are there and the IDE know where they are.

But i still have the error when building.

I tried the following things:

-refresh the project

-rebuild index & freshen all files

-remove the .h, refresh, put back the .h, refresh

-remove & import again the project.

Nothing fixed it and i'm running out of idea to try fixing the issue.

Ensure the directory of the header file is listed in your include paths for the compiler.

right click project -> Properties -> C/C++ Build -> Settings -> Tool Settings -> MCU GCC Compiler -> Include paths

That was my issue... I feel stupid.

Thanks you for your answer!

Sorry to bring this thread up again. If I want to add new header file to one of the Include paths, how can I update that path to display the new added header files?

Right now, I added new header files in Core/Inc (not shown in Project Explorer) but when I expand Core/Inc, the new added header files are not there.

Should be a refresh option. F5 or right click refresh or something.

Hello, thank you for your response. I did that already but nothing was updated. This was one of the thing I did: Via File Explorer at the Core/Inc, I created a file called testing.h. Then, although I refreshed the Project Explorer tab many times, there was no testing.h in the red area.

The screenshot you posted is not a file listing of a directory, it is a list of files included in the project, hence the “Included�? node above them. The file listing is farther down the screen.
This feels like a different issue than the OP.

I am sorry. I looked at a wrong direction. That is why I could not find my newly created files. Thank you very much for your response.

Hi, I'm having a similar problem. When compiling, I have errors saying that header files do not exist. The project is a simple PWM on a LED. The include paths are configured. I cleaned the project, workspace, etc and restarted everything but the errors are still there. Any idea on how to solve this problem?

Example:

.../Middlewares/ST/STM32_USB_Host_Library/Core/Src/usbh_core.c:22:10: fatal error: usbh_core.h: No such file or directory
   22 | #include "usbh_core.h"
      |          ^~~~~~~~~~~~~

usbh_core.h is in /Middlewares/ST/STM32_USB_Host_Library/Core/Inc which is a configured path (see screenshot)

 

P-S: F3 does work so the IDE recognises the files.
