How to test build using Aboriginal Linux system images.
|
|
|
|
* Put a source tree into hdc.dir/.
|
|
For example, this should work:
|
|
git clone git://busybox.net/var/lib/git/busybox.git
|
|
|
|
* Run ./make-hdc-img.sh: it will generate ext2 image file,
|
|
hdc.img, from hdc.dir/* data. This requires root for loop mount.
|
|
|
|
* Download and unpack, or build from source and unpack
|
|
one or more system-image-ARCH directories into this directory
|
|
(the one which contains this README).
|
|
|
|
* Install qemu-system-ARCH. The arch names may differ from
|
|
system-image-ARCH: for example, all ARM flavors (armv4l...armv6l)
|
|
are served by the same qemu - qemu-system-arm. On my machine,
|
|
I needed to install qemu-system-{arm,mips,x86,ppc,sparc,m68k,sh4}.
|
|
|
|
* Run: ./parallel-build-hdc-img.sh system-image-DIR1 system-image-DIR2...
|
|
(background it if you don't want to see "Waiting to finish" thing).
|
|
This runs build in several qemu virtual machines in parallel.
|
|
|
|
* Observe system-image-*.log file(s) with growing log of the build.
|
|
|
|
There is no automated detection of errors for now: you need to examine
|
|
logs yourself.
|
|
|
|
Log files will also contain uuencoded (or if all else fails, od -tx1'ed)
|
|
binary, if build was successful.
|
|
|
|
To debug a build problem in one of the sandboxes, change keep_hdb
|
|
to "keep_hdb=true" in parallel-build-hdc-img.sh
|
|
- this preserves system-image-ARCH/hdb.img after the build,
|
|
so you can go into system-image-ARCH and run
|
|
"HDB=hdb.img ./dev-environment.sh" to debug the problem.
|
|
|
|
You can also run "./parallel-build-hdc-img.sh -s system-image-ARCH"
|
|
- single mode, output is to screen and serial input is from keyboard.
|
|
|
|
If hdc.dir/bin/busybox-$ARCH exists, it will be used during build
|
|
to supply additional tools (dir with all applets appended to $PATH).
|
|
|
|
For me, the following system images worked:
|
|
system-image-armv4l
|
|
system-image-armv4tl
|
|
system-image-armv5l
|
|
od is buggy on arm*:
|
|
# echo Hello-hello-hello-hello | od -b
|
|
0000000 110 145 154 154 157 055 150 145 154 154 157 055 150 145 154 154
|
|
0000000 157 055 150 145 154 154 157 012 <= WRONG OFFSET
|
|
0000000 (can also be even more bogus like 17767153361)
|
|
system-image-i686
|
|
system-image-mips - od is buggy
|
|
system-image-mipsel - od is buggy
|
|
system-image-x86_64
|
|
system-image-powerpc - qemu 1.2.2 didn't work, 2.4.0 worked; od is buggy
|
|
system-image-sparc - qemu 1.2.2 didn't work, 2.4.0 worked; od is buggy
|
|
|
|
And these did not:
|
|
system-image-armv6l - hang on "Uncompressing Linux... done, booting the kernel"
|
|
system-image-m68k - my qemu doesn't like "-M q800"
|
|
system-image-mips64 - init dies "Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000a"
|
|
system-image-sh4 - qemu segfaults early in kernel boot
