Blink.ino does not build. Missing header variant file

[berrak]

Describe the problem

I tried to build Blink.ino for an STM32 populated board, but this results in fatal error: variant_GENERIC_G031F8PX.h: No such file or directory. One may think this has not to do with the IDE itself. However, I'm not 100% sure about that since the same file and board build and run just fine in IDE 1.8.19.

To reproduce

• Unzipped IDE in: /opt/Arduino/Arduino-ide_2.0.0-rc9_Linux_64bit
• Updated STM32core to the latest version 2.3.0 with G031F8P6-support.
  (https://github.com/stm32duino/Arduino_Core_STM32)
• Build and tried to run 'blink.ino', but build failed with missing header file (variant_GENERIC_G031F8PX.h)
• However, an identical 'blink.ino' builds and runs without problem in IDE 1.8.19. (see below)

Expected behavior

Build should not fail.

Arduino IDE version

arduino-ide_nightly-20220723_Linux_64bit.AppImage

Operating system

Linux

Operating system version

11 (Bullseye)

Additional context

Detailed error output at build time in IDE 2.0.0.rc9 - same error with latest nightly build IDE.

Hi @berrak. Thanks for your report.

I see we have another report about this at arduino/arduino-cli#1614 (Arduino IDE 2.x uses Arduino CLI for the sketch compilation operation, so the bug in Arduino CLI also affects Arduino IDE 2.x users).

It is best to have only a single issue per subject so we can consolidate all relevant discussion to one place, so I'll go ahead and close this in favor of the other.

If you end up with additional information to share, feel free to comment in the other thread.

Workaround

I'll share the workaround for the issue:

1. Open this file with a text editor:

   /home/bekr/.arduino15/packages/STMicroelectronics/hardware/stm32/2.3.0/boards.txt
   

   ❗ If looking for it with your file browser or command line, note that /home/bekr/.arduino15 is hidden by default.
2. Add the following line anywhere in the file:

   GenG0.menu.pnum.GENERIC_G031F8PX.build.variant_h=variant_generic.h
   

3. Save the file.
4. Close all Arduino IDE windows and then restart if you have the Arduino IDE running.

You should now be able to compile for the "Generic STM32G0 series" board with Tools > Board part number > Generic G031F8Px selected.

Note that you will need to redo the modification to boards.txt after every update of the STM32 boards platform.

Thanks so much; for the workaround, and thanks for the quick response to my report.
Cheers.
