eo_step gdb script installation to help debugging of applications by
stepping over Eo. To do it: - Write in ~/.gdbinit "source prefix/share/eo/eo_step.py" (prefix is usually/opt/e17) - in gdb, when arriving to eo_function (eo_do, eo_do_super), execute eo_step. This script will step into the code until it reaches a function that doesn't belong to libeo. Because of a bug in gdb that will be fixed in 7.6, if after having used the script once, you rerun your application and reexecute the script, a segmentation fault can occur. Sorry for the inconvenience. Signed-off-by: Daniel Zaoui <daniel.zaoui@samsung.com> SVN revision: 80760
