I am trying to compile one of my project (https://github.com/leElvyn/auto-smash/tree/main/firmware) from my macos computer. Usually, i am using my main computer to do that, a windows PC with WSL ubuntu, and it is working perfectly, but when using my macos computer :

I work on one AVR project that's targeting AVR128DB28 and have found out that avr-gcc (even the newest version 11) doesn't support it (i.e avr/io.h is not defined for it in /usr/local/Cellar/[email protected]/11.1.0_1/avr/include/avr).

Here's a related avr freaks thread.

Is there any chance that header files for those newer MCUs will be added to avr-libc? I know this is not necessarily the place to ask this question but as of now, I'm just not sure where else to ask this.

Added patch suggested by https://github.com/osx-cross/homebrew-avr/issues/251#issuecomment-879036177 to resolve issue loading avr elf files into avr-gdb.

Solves the issue raised by #251 by implementing the fix proposed by #255.

This PR simply includes the patch file. A subsequent PR will introduce the code that applies the patch to elf-gdb.h using the resulting Github URL created for the patch file.
