Script for creating RaspberryPi ross compile sysroot on macOS
The idea for this script is based on the post by (Harld Fernengel)[https://medium.com/@haraldfernengel/cross-compiling-c-c-from-macos-to-raspberry-pi-in-2-easy-steps-23f391a8c63]
This script is intended to be used on macOS and has the same dependencies as mentioned by Harald:
brew install arm-linux-gnueabi-binutils
brew install llvm
brew install rsync
You will also need a live RaspberryPi system and an SSH connection to it.
The script code mksysroot is reasonably well documented, but in short,
it does the following:
- Sets up local directory for sysroot.
- Copies sysroot files from RaspberryPi.
- Adjusts the makefile
RPi.mk.
To use simply point to your Raspberry SSH and specify local name for sysroot directory. For example:
~/github/mksysroot/mksysroot pi@mypi: RPi1A
That will create a sysroot directory RPi1A. It that directory you will find
RPi.mk file and test directory. The test directory contains very simlpe
tests for compiling C and C++ apps to make sure your setup works.
To compile test apps:
make -C RPi1A/test all
Then just copy RPi1A/test/test and RPi1A/test/testpp to your RaspberryPi
and run there.
