<< < (4/5) > >>

ollydbg:
@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.

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?

oBFusCATed:
I've added an option to set custom arguments to gdb, please test it and report if it really works.

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