My C::B's gdb debugger didn't work in ubuntu :(

[tigertang]

everytime i tried to set a breakpoint and debug, the terminal told me this:
Setting breakpoints
Debugger name and version: GNU gdb (Ubuntu 7.12.50.20170314-0ubuntu1) 7.12.50.20170314-git
Undefined command: "tty".  Try "help".
At /home/***/code/projectCpp/main.cpp:7
unfortuately, pressing f7 at this time...Oops!
It seems that debugger isn't willing to work anymore....


Please help me...
Thank you guys very much!

The information you've provided is not enough to understand where the problem lies, so we'll need a bit more.
Can you enable full logging in the settings -> debugger, reproduce the problem and then post the log using code tags or in some pastebin?

Does this gives enough information?

For some reason your gdb doesn't support the tty command

Code

[debug]> tty /dev/pts/0
[debug]Undefined command: "tty".  Try "help".

Why do you use 7.12.50.xxxx? As far as I know these are development snapshots.
Can you try to install 7.12 or 7.12.1?
These are known to work correctly with codeblocks.

I have the same problem on Ubuntu 17.04 with the same gdb version(7.12.50~).
For unknown reason, tty command is no longer provided by this gdb. But tty command is actually the alias of "set inferior-tty"
(reference:
 https://sourceware.org/gdb/onlinedocs/gdb/Input_002fOutput.html).
So my solution to this issue is to replace "tty " with "set inferior-tty " in codeblocks' sorce file: trunk/src/plugins/debuggergdb/debuggergdb.cpp:924.

This is an acknowledged bug in this version of gdb.
For some reason this ubuntu ships with a development version of gdb.
This should be fixed in later versions of gdb.

Please ask ubuntu developers to update the gdb package to a release version.
