Thanks for the quick reply! With the master build, I run into an error quite quickly (following instructions from crosstool-ng.org). [DEBUG] ==> Executing: 'mkdir' '-p' '/build' [ALL ] mkdir: /build: Permission denied - Full log: https://scriptreactor.com/rpi1-master-build.log Any idea what's going on here? Trying out with your adjusted settings on 1.22 for now.

This prohibits crosstool-ng from applying any patches it has for any packages.

Likely it is one in patches/glibc/2.19, patches/binutils/2.25.1 or patches/gcc/4.9.4. > > As a side note, I'd recommend using master on macos rather than 1.22 - there has been a lot of macos fixes since. > > Regards, > Alexey. > > > On 03/09/2017 04:15 AM, Etan Kissling wrote: >> Hi, >> >> I'm trying to build a toolchain that supports cross compilation for the Raspberry Pi Zero W. >> This requires building for ARMv6 (same as for the old Raspberry Pi 1). >> >> The official repository contains a crosstool-ng config file here: >> https://github.com/raspberrypi/tools/blob/master/configs/arm-rpi-4.9.3-linux-gnueabihf.config >> Unfortunately, only Linux binaries are provided in the repo.
