Build fails with latest arduino-esp32 3.0.0 RC1

[kb1sph]

After setting up sloeber on a new laptop and installing arduino-esp32, I got the following error.

I realized afterwards that it is due to a newer version of arduino-esp32.

It seems this was noticed by someone else and reported on another repository and fixed. Perhaps the link to that could help.

Will there be an official patch for this? Because the two defines aren't the only things that needed to be "fixed". Until I got my project to compile, it required these defines to be fixed by adding them to the compile-options tab as parameters for the c and c++ compiler calls of the sloeber project options:

-DARDUINO_HOST_OS="\"generic_os\"" -DARDUINO_FQBN="\"generic_board\"" -DARDUINO_VARIANT="\"adafruit_metro_esp32s3\""

Please note that the last one is originally added, but without the escaped quotation marks, which leads the build-process to break, as the value of the define is not interpreted as a string, but as symbol that cannot be resolved.

Since the file boards.sloeber.txt, from which this value seems to originate, is autogenerated, I presume it needs to be fixed either there, or wherever the makefiles are created... I haven't analyzed this further, as I was glad that my project was finally compiling.

However, a proper official solution / patch would with the proper fixes in the proper places would be highly appreciated.

It will be fixed but I'm currently working on a very big change (https://github.com/Sloeber/arduino-eclipse-plugin/tree/%231126_support_for_creating_library_archives) which is done but now I need to fix lots of regression (unrelated things that no longer work) issues.

I have run into this as well. How can I assist.

Thank you.
