Build scripts for building GenPi64 images.
Linux system (gcc, chroot, et cetera) Python3.9 pychroot git dev-python/python-lockfile dev-python/iniparse qemu with xattrs enabled.
btrfs-progs (or change the filesystem type and mount options in config/config.py)
sgdisk (for gpt based disk images)
sfdisk (for mbr based disk images)
qemu user static for aarch64 and arm
- qemu needs to be emerged with USE="static-user".
wget
You need to download the stage 3 tarball you want to use, and put it in build-binary-assets/stage3.
Edit config/config.py and update the path to the stage3 version you're using.
Pick a target by running
export PROJECT=<projectname>
default is GenPi64.
If you want to set where the build should happen, run
export PROJECT_DIR=</path/to/build/location>
default is $PWD/build/$PROJECT.
Then run sh build.sh. Wait (a long time). At the end, you should have your output in $PROJECT_DIR.
Packages are in $PROJECT_DIR/packages, the image file is in $PROJECT_DIR/. There's also a stage4 generated,
in the same location.
If you are building an arm target via qemu, you probably want a distcc server running with crossdev gcc.
You can configure the project via config/config.py, the default one is fairly fleshed out, so feel free to poke at it to see how it works.
The steps to execute are governed by the .json files in the project root.
Compiling python often hangs running compileall.py. It's safe to kill the hung tasks.
If you're getting "bad interpreter" errors, make sure you have qemu.
If . env.sh you can manually run a parser and better assess its output. You can also pychroot $CHROOT_DIR and manually tweak things inside the prefix.
