Raspberry Pi Cross Compilation SDK

Clang 6 based toolchain and GN buildroot for setting up a cross-compilation environment for the Raspberry Pi.

Prerequisites

• A Mac or Linux host and a Raspberry Pi.

Usage for Raspberry Pi

• Download the prepared toolchain, sysroot and related tools to the out directory ./tools/setup_sdk.sh.
  • This takes a while and downloads upto 1 GB of data from cloud storage.
• Prepare the build output directory out with paths to your toolchain using ./tools/setup_gn.sh.
• Build using ninja -C out on your host.
  • Hack and repeat.
• Push your executable to the Raspberry Pi and run.
  • You should probably mount the out directory to the remote Raspberry Pi using SSHFS. That way, the build artifacts automatically end up getting pushed to the Pi.
