| How to test strace build using Aboriginal Linux's system images. |
| |
| * Put a autoconf'ed strace source tree into hdc.dir/strace dir. |
| For example, this should work: |
| git clone git://strace.git.sourceforge.net/gitroot/strace/strace && |
| cd strace && ./bootstrap |
| |
| * 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 a strace build in several qemu virtual machines in parallel. |
| |
| * Observe system-image-*.log file(s) with growing log of strace build. |
| |
| There is no automated detection of errors for now: you need to examine |
| logs yourself. |
| |
| For me, the following system images worked (tests passed/skipped/failed): |
| system-image-armv4l - 14/14/1 (failed: stat32-v.test - wrong stat decoding, sun_path.test - libc error) |
| system-image-armv4tl - 15/14/0 |
| system-image-armv5l - 15/14/0 |
| system-image-armv6l - 15/14/0 |
| system-image-i486 - 14/14/1 (failed: count.test - grep segfault) |
| system-image-i586 - 14/14/1 (failed: count.test - grep segfault) |
| system-image-i686 - 14/14/1 (failed: count.test - grep segfault) |
| system-image-mips - 15/14/0 |
| system-image-mipsel - 15/14/0 |
| system-image-powerpc - 13/14/2 (failed: ipc_sem.test - ipc_sem segfault) |
| system-image-sparc - 13/14/2 (failed: ipc_sem.test - ipc_sem segfault) |
| system-image-x86_64 - 14/15/0 |
| |
| And these did not: |
| system-image-m68k - qemu-system-m68k: -M q800: Unsupported machine type |
| system-image-mips64 - init dies before reaching /mnt/init |
| system-image-sh4 - hdc does not mount (no support for 2 disks) |
| |
| |
| To debug a build problem in one of sandboxes, change keep_hdb |
| to "keep_hdb=true" in parallel-build-hdc-img.sh |
| |
| This preserves system-image-DIR1/hdb.img after the build, |
| so you can go into system-image-DIR1 and run |
| "HDB=hdb.img ./dev-environment.sh" to debug the problem. |
