This is a fork of Tim Bird's experimental crash_handler program.
This fork uses libunwind (http://www.nongnu.org/libunwind/) to provide a more robust way of doing stack unwinding.
It operates very similarly to Android's debuggerd, but requires no persistently-running process. Much of this code came, originally, from debuggerd. It uses /proc and ptrace calls to gather information about the dying process. It records the information into a crash report, and also records summary information into a crash journal.
The project home page is at:
http://elinux.org/Crash_handler
To build this code, type 'make'.
If you are cross-compiling, then first set the CROSS_COMPILE environment variable, to contain a toolchain prefix. This should include the trailing dash that is customary for a toolchain prefix. For example:
$ export CROSS_COMPILE=arm-sony-linux-gnueabi-armv7a-dev-
Your toolchain prefix is likely to be much simpler than this, and may be something like: 'arm-eabi-' or 'arm-unknown-linux-gnu-'
You must be root to install the crash_handler.
To install this code, copy it to some location on the target, and type: $ ./crash_handler install
By convention, I install this binary in /usr/bin, but it can be placed anywhere. The crash journal is created in /tmp, and crash reports are created in /tmp/crash_reports
The 'make install' command uses an internal Sony tool called ttc to perform this installation. This won't work for you. You can change the 'install' target in the Makefile to the following line:
install: default_install
