Re: vim - gdb communication problem

Hi All.

The issue was resolved by changing #!/bin/sh to #!/bin/bash in sh script.

It seems like the bug in dash, which is /bin/sh pointed to (ubuntu).

Thanks

I've checked the following schema:

sh -> expect -> gdb -> myApplication

vim -> sh -> expect ->  myApplication

Both works well with SIGQUIT. 

But this

vim -> sh -> expect -> gdb -> myApplication

returns to vim while gdb process still exists.

And it allow to move vim cursor and run gdb commands in time.  

It seems like the bug in Vim 7.3.154. Any ideas?

It tried to compile Vim 7.1 in ubuntu 11.10. It compiled well but I can't run it cause it crashed with buffer overflow.

Hi All.

I am using vim with gdb through expect script.

I have key mapped to sh script which call expect script which call gdb which call my console application.

vim -> sh -> expect -> gdb -> myApplication

So when I pressing ;d in vim I got GDB with my application started and breakpoint set to string where vim cursor pointed.

I am using the folowing code in my expect script.  

trap interact {SIGQUIT}

This allow me to stop expect script manually by pressing Control-\ which sends SIGQUIT to expect and give control to me.

I am migrating from fedora core 4 to ubuntu 11.10.

And all works except one issue:

When I press Control-\ in ubuntu I got not gdb or application on the screen but I got messed screen with vim and gdb and my application.

And it messed while I not send SIGKILL to vim.

Here is terminal settings for both OS:

Ubuntu 11.10:

c@cwd:~$ stty -a

I can't understand what is wrong. Could you please help me to resolve the issue?

Thanks
