1 How to test strace build using Aboriginal Linux's system images.
2
3 * Put a autoconf'ed strace source tree into hdc.dir/strace dir.
4 For example, this should work:
5 git clone git://strace.git.sourceforge.net/gitroot/strace/strace &&
6 cd strace && ./bootstrap
7
8 * Run ./make-hdc-img.sh: it will generate ext2 image file,
9 hdc.img, from hdc.dir/* data. This requires root for loop mount.
10
11 * Download and unpack, or build from source and unpack
12 one or more system-image-ARCH directories into this directory
13 (the one which contains this README).
14
15 * Run: ./parallel-build-hdc-img.sh system-image-DIR1 system-image-DIR2...
16 (background it if you don't want to see "Waiting to finish" thing).
17 This runs a strace build in several qemu virtual machines in parallel.
18
19 * Observe system-image-*.log file(s) with growing log of strace build.
20
21 There is no automated detection of errors for now: you need to examine
22 logs yourself.
23
24 For me, the following system images worked:
25 system-image-armv4l
26 system-image-armv4tl
27 system-image-armv5l
28 system-image-armv6l
29 system-image-i686 (had to s/qemu-system-i386/qemu/ in run-emulator.sh)
30 system-image-mipsel
31 system-image-mips
32 system-image-x86_64
33 system-image-sparc - needed small edit in native-build.sh:
34 # Getting this early:
35 # Unhandled Exception 0x00000007
36 # PC = 0xffd07cec NPC = 0xffd07cf0
37 # Stopping execution
38 # and it looks like it's triggered just by too long kernel cmdline,
39 # not by specific options.
40 #export KERNEL_EXTRA="FTP_SERVER=$FTP_SERVER FTP_PORT=$FTP_PORT NATIVE_BUILD=$NATIVE_BUILD $KERNEL_EXTRA"
41 # This works:
42 export KERNEL_EXTRA="NATIVE_BUILD=$NATIVE_BUILD $KERNEL_EXTRA"
43
44 And these did not:
45 system-image-armv4eb - VFS: Cannot open root device "sda" or unknown-block(0,0)
46 system-image-m68k - run-emulator.sh has no call of qemu-system-* (not supported yet??)
47 system-image-mips64 -
48 need to run ./native-build.sh ../hdc.img by hand;
49 copying in /mnt/init fails (segv?)
50 system-image-powerpc - QEMU stuck very early
51 system-image-sh4 - hdc does not mount (no support for 2 disks)
