Are you tired of the fact that every time you build your kernel in pmbootstrap it starts biulding it from scratch? Does it take too much time? and envkernel does not work/broken? Then this is for you!
Prepare config and chroots:
pmbootstrap -y zap pmbootstrap init # for your device
Start building your kernel but cancel early; download all source and checksum; wait until it and starts build, this way we'll have all sources unpacked and placed where needed, and dependencies prepared:
pmbootstrap checksum linux-your-kernel pmbootstrap build --force --arch aarch64 linux-your-kernel ^C # press Ctrl+C as soon as pmbootstrap log starts to show building process
Switch to native chroot:
pmbootstrap chroot
In native chroot verify that all deps are installed (this is run as root user inside chroot):
apk add abuild build-base ccache git devicepkg-dev mkbootimg postmarketos-base ccache-cross-symlinks gcc-aarch64 g++-aarch64 crossdirect ncurses-dev bash bc bison elfutils-dev flex gmp-dev installkernel linux-headers openssl-dev perl sed
The following build commands (make or abuild invocations) are run in native chroot as pmos user!
su pmos export HOME=/home/pmos cd /home/pmos/build # the directory where APKBUILD file is
You can restart all your build from the beginning with this:
cd /home/pmos/build # the directory where APKBUILD file is rm -rf src abuild fetch verify unpack prepare
Build (repeat multiple times during development): this does not restart full kernel build every time
export ARCH=arm64 export CARCH=aarch64 export CROSS_COMPILE=aarch64-alpine-linux-musl- export CC=aarch64-alpine-linux-musl-gcc abuild -df build
OR manually
cd /home/pmos/build/src # or whatever the directory after unpacking kernel archive would be make ARCH=arm64 CROSS_COMPILE=aarch64-alpine-linux-musl- defconfig make ARCH=arm64 CROSS_COMPILE=aarch64-alpine-linux-musl- menuconfig make ARCH=arm64 CROSS_COMPILE=aarch64-alpine-linux-musl- -j9 make ARCH=arm64 mrproper
If you want to build as package:
abuild package # or abuild rootpkg # (?) not tested yet
Hope it helps!
