New page

== Description ==

''maemo-debug-scripts'' is a convenience package for maemo developers needing to debug their programs. The package will:

* Post-install a symlink required by Gdb/Valgrind/Oprofile to find the debug symbol files in Scratchbox. The files are installed in ''/usr/lib/debug/<library path>'', but in Scratchbox the library realpaths are ''/targets/<target name>/<library path>''.

* Depend from libc6-dbg. Without libc6-dbg threads cannot be debugged with Gdb and Valgrind reports redundant errors for the dynamic loader (its error suppressions for /lib/ld functions can match them only with the debug symbol file as stripped binary doesn't contain static function names)

* Depend from target native Gdb. The Scratchbox host version of Gdb (cross-gdb) doesn't know how to load the correct thread library (even on x86) and it cannot debug ARM core-dumps. Native one can.

* Install a few helper scripts:
** ''native-gdb''
::runs the target native Gdb (by default Scratchbox runs the host binary if it exists, this script overrides that)
** ''debug-dep-install''
::installs debug symbols for given binaries and their dependencies listed by "ldd"
** ''debug-pkg-check''
::checks the correctness of a debug package for a given package
** ''list-mmapped-libs''
::lists all packages containing libs and binaries that given process uses. It can be used to find out the libraries mmap()ed through dlopen that "ldd" (used by debug-deb-install script) doesn't find
** ''run-with-valgrind''
::helper script for running a binary with Valgrind memcheck plugin (memory access errors, leaks etc) so that all suitable options are set for it
** ''run-with-callgrind''
::helper script for running a binary with Valgrind callgrind plugin (performance profiling) so that all suitable options are set for it
** ''run-with-massif''
::helper script for running a binary with Valgrind massif plugin (memory usage visualization) so that all suitable options are set for it
** ''run-with-helgrind''
::helper script for running a binary with Valgrind helgrind plugin (race condition detector for threaded programs) so that all suitable options are set
** ''run-with-strace''
::helper script for running a binary with strace. Like above helper scripts, handles maemo-launched binaries automatically
