Yay! In other test harness news, I've put a lot of work into https://github.com/landley/mkroot in the past week or so (simple musl-libc test environment booting under qemu), and if you run the mcm-buildall.sh script against https://github.com/richfelker/musl-cross-make and then do something like CROSS_COMPILE=~/musl-cross-make/output/aarch64-linux-musleabi-cross/bin/aarch64-linux-musleabi- ./mkroot.sh dropbear kernel If it works you can then cd output/aarch64" and ./qemu-aarch64.sh and it should boot you into a little emulated system. I haven't got the whole https://landley.net/aboriginal/control-images infrastructure reproduced yet, but I'm working on it. I'd love to point CROSS_COMPILE at the NDK toolchains and try to get those to work too. (Although the main reason I can use musl-cross-make is I made puppy eyes at Rich to provide _native_ compilers, so my little emulated environment can natively build stuff in the emulator. I need to write and check in a module/distcc for mkroot so I can do the distcc trick from http://landley.net/aboriginal/about.html and I see qemu thinks it's grown multi-threaded SMP support, which might actually make use of SMP on the host. I should poke at it, the single-cpu emulator could only keep about 3 distcc slaves running on the host and even I've got an 8-way SMP system...) > $ ./android-ndk-r15-beta2/build/tools/make_standalone_toolchain.py > --unified-headers --arch arm64 --api 24 --install-dir > /tmp/n-standalone-toolchain Is there somewhere I can download ndk snapshots from? https://developer.android.com/ndk/downloads/index.html just has beta 1... > $ git clone https://github.com/landley/toybox.git > $ cd toybox > $ CC=clang > CROSS_COMPILE=/tmp/n-standalone-toolchain/bin/aarch64-linux-android- > make defconfig > $ CC=clang > CROSS_COMPILE=/tmp/n-standalone-toolchain/bin/aarch64-linux-android- make > > i've attached one patch to make mkpasswd not part of the "defconfig" for > Android, since (a) we don't have passwd and (b) we don't have crypt(3). > so it wouldn't be any use and you can't build it anyway. > > i've attached another patch to add liblog to the list of probed > libraries so that toybox actually links okay. Applied both, although I had to fix up the second so it installed on top of your -libz patch. > with that there's only one problem left (ignoring compiler warnings, and > the fact that selinux and boringssl aren't part of the NDK so you'll be > without working versions of any of the selinux stuff or fast versions of Out of curiosity, why not? > the hash stuff) --- there is no public API for the > <cutils/sched_policy.h>, so that still won't build out of the box.
