recipe.preproc.macros pattern is missing Arduino 1.8.19

recipe.preproc.macros pattern is missing Error compiling for board Generic x86 computer.

Arduino would not recognize the new hardware folder until boards.txt was inside one of the subdirectories.

Building on windows 7, can test on a linux system later if necessary, I figure this was just a misplaced file.

Hi, I never got around to test boot2duino on Windows. Can you reproduce the issue on Linux?

Sorry for delay; compiling any example on Linux 4.19.0-17-amd64 #1 SMP Debian 4.19.194-3 (2021-07-18) x86_64 GNU/Linux, running Arduino 1.8.13

GNU ld (GNU Binutils for Debian) 2.31.1

Strangely, this system doesn't complain about the location of boards.txt.

I assume you have GCC < 11, could you try updating to 11 or later? It seems to fix the issue (see https://github.com/jeanthom/boot2duino/issues/6)
