| 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). |
| |
| * 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 |
