Code::Blocks - warning: GDB: Failed to set controlling terminal: Operation not permitted

Question

I've installed Code::Blocks 13.12 in Ubuntu 14.04 through official repositories. When I compile, everything goes OK. But when I debug, the following message is shown at the shell:

warning: GDB: Failed to set controlling terminal: Operation not permitted

And the program is executed up to the breaking point, but nothing more is shown when I execute the next lines.

How to fix this?

PD: I've installed the latest version of GDB (the one which is in repositories). I've also tried to use the linux terminal instead of the one Codeblocks shows.

Answer 1

I think this just means that code::blocks is running gdb in "CLI" mode without making a pseudo-terminal. So, when gdb tries terminal operations, they fail. You can just ignore these messages.

Answer 2

Heh, this problem still exists in 2020...

I've installed Code::Blocks 1.6 on clear CentOS 7 installation and got the same messages and behavior.

For me, this is solved by disabling SELinux which prevented IDE from using debugger.
