Description Jakub 2023-03-01 13:26:51 UTC 
HI, 
I'm trying to run Buildroot on Apple Silicon, I'm unable to do that since I'm getting an error with linking the libraries.
After running 'make menuconfig' I'm getting an error 'Undefined symbols for architecture arm64' (top of Attachment 2 for full log), I was able to solve it by running 
'❯ cd output/build/buildroot-config'
'❯ /usr/local/bin/gcc -DCURSES_LOC="<curses.h>" -DLOCALE -DKBUILD_NO_NLS -I/Users/jakubswistak/Desktop/lines2/buildroot-2022.11.1/output/build/buildroot-config -DCONFIG_=\"\"   /Users/jakubswistak/Desktop/lines2/buildroot-2022.11.1/output/build/buildroot-config/mconf.o /Users/jakubswistak/Desktop/lines2/buildroot-2022.11.1/output/build/buildroot-config/zconf.tab.o /Users/jakubswistak/Desktop/lines2/buildroot-2022.11.1/output/build/buildroot-config/lxdialog/checklist.o /Users/jakubswistak/Desktop/lines2/buildroot-2022.11.1/output/build/buildroot-config/lxdialog/util.o /Users/jakubswistak/Desktop/lines2/buildroot-2022.11.1/output/build/buildroot-config/lxdialog/inputbox.o /Users/jakubswistak/Desktop/lines2/buildroot-2022.11.1/output/build/buildroot-config/lxdialog/textbox.o /Users/jakubswistak/Desktop/lines2/buildroot-2022.11.1/output/build/buildroot-config/lxdialog/yesno.o /Users/jakubswistak/Desktop/lines2/buildroot-2022.11.1/output/build/buildroot-config/lxdialog/menubox.o  -o /Users/jakubswistak/Desktop/lines2/buildroot-2022.11.1/output/build/buildroot-config/mconf -lncurses' - added '-lncurses' 
But later during the compilation 'make'
I'm getting another error with linking library (bottom of Attachment 2 for full log) 

I'm using Apple M2 chip with gcc/g++ 12.2.0 installed via homebrew.

Buildroot should mostly work on apple silicon, I have an autobuilder running on a M1 mac mini myself:

Are you using the arch based Asahi Linux(https://asahilinux.org/)?

Building on MacOS is unlikely to work, you really need to build on a Linux machine. x86-64 naturally gets most testing, but conceptually it should work to build on an arm64 Linux machine as well (except for the prebuilt external toolchains and similar).

I'm using macOS Ventura 13.2.1 and building an image for raspberry pi

Yeah, buildroot needs a Linux based host OS, macOS isn't going to work. You need to install something like Asahi Linux, a aarch64 virtual machine may also work via qemu or something.
