Using and GDB scripts

Some time ago, Alexander Larson blogged about using gdb python macros when debugging Glib and GObject projects. I've wanted to try those for ages, so I spent part of the week-end looking at what you could do with the new python enabled GDB, result: quite a lot of neat stuff!

Let's start by making the script that now comes with glib work on stock gdb 7.0 and 7.1 (ie not the archer branch that contains more of the python work). If those two scripts don't work for you yet (because your distribution is not packaging them, or is packaging a stock gdb 7.0. 7.1), here are a few hints you can follow:
glib's GDB macros rely on GDB's auto-load feature, ie, every time GDB load a library your program uses, it'll look for a corresponding python script to execute:open("/lib/", O_RDONLY) open("/usr/lib/debug/lib/", O_RDONLY) open("/usr/share/gdb/auto-load/lib/…
