IMO *if* gdb wanted to support people adding files to *its* <sysroot>/share/gdb directory, more thought is needed - e.g. maybe document a "site" directory for such files. Dunno. IMO we certainly don't want to formally allow folks to willy-nilly put anything there - no guarantees a future release might add something that collides with something the user put there. If and until then, you're probably pretty safe if you put everything in a subdirectory with a unique enough name, if you really wanted to go this route. Btw, there is the system.gdbinit file which sites *are* free to customize. E.g., configure --with-system-gdbinit=<sysroot>/share/gdb/system.gdbinit. You can put whatever you want in that file. E.g., you could add a directory to python's sys.path. [Technically speaking, the path <sysroot>/share/gdb/system.gdbinit goes against what I just said, but IMO this name is safe.] -- http://mail.python.org/mailman/listinfo/python-list
