Re: [cdt-dev] Startting remote program from GDB using "target remote"

[Roman Levenstein <romixlev@xxxxxxxxx>]

Hi Mikhail,

Now it works. Thanks!

BTW, I'd like to submit some "free-form" commands
(i.e. not  to GDB programmatically, as if they were
entered by the user or read from .gdbinit file. The
idea is to have something like .gdbinit scripts, but
to be able to execute them at any time during the
debugging. Which class/method should I look at? I
guess, I just need to get access to the input
(console) stream of GDB process and basically write
the GDB commands into it, or?

Thanks,
 Roman
