@xunxun, here is the log of gdb (without the hack of gdb's share path), it shows both worked and un-worked condition.

the gdb's shared folder is used when it's python module is initialized. but the python module is running before you "set-directory" command.
so the only way to set the data-directory is setting that path as gdb parameters, like "gdb --data-directory=XXX"

the other way such as “set data-directory XXX” can not work.



If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

so we can use the command :
gdb -ex "set data-directory e:\mypack\mingw\share\gdb"
Why would you do this instead of passing --data-dir?

I want to make gdb auto source this script, but .gdbinit must be in the current directory, so "-ex" only is the test.

Can we redefine gdb.PYTHONDIR to gdb's data directory in python.c?

I've added an option to set custom arguments to gdb, please test it and report if it really works.
(most of the time I ignore long posts)
[strangers don't send me private messages, I'll ignore them; post a topic in the forum, but first read the rules!]

I will test it ASAP, currently I can't synchonize SVN now due to network issue. :)

Setting gdb startup arguments works fine.

Thank you!

PS:
Under MinGW, if you would like to Automatically load gdb's own python pretty script, you still  need to hack the gdb's source code, as I said before, it can't be done by pass the "-data-directory ...." in the gdb's startup arguments.
