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) 52
