The program works if I use the SSH console, but it doesn’t stop at any breakpoint either, which is the real issue. It probably has nothing to do with VisualGDB.
As soon as I type run (or -exec-run), the program starts and stays up. it goes way beyond the breakpoint inserted in main. There’s no running message. I can’t really redirect the program output to pts/1 when I run manually, so what I see in GDB is the program output, I am not sure how to check the GDB logs past that point.

Here’s what I get for the simple HelloWorld sample. The program goes through the breakpoint set in main as if it wasn’t there.

I am not sure that breakpoints work in this config.
If I use VisualGDB to create a new Hello World project. If I put a breakpoint in the main. it won’t stop on the breakpoint. I saw that there supposed to be a breakpoint inserted at the beginning of main by VisualGDB too, I don’t think it’s hit either.

[cperthuis]

But the application doesn’t fail initializing, GDB is actually starting it correctly even though VisualGDB fails to acknowledge it.
As long as I don’t press Abort in the window, I am getting all the output I am supposed and the app is fully functional. it’s a server, and I can interact with it fine.

[cperthuis]

Here’s more info to reproduce the issue.
I am using VirtualBox 4.3.16, I forwarded 2222 onto 2222 and 22 onto 22.
I installed Ubuntu 14.04 server in the VM.

In the VM:

sudo -i
apt-get update
apt-get install vim openSSH-server docker.io
ln -sf /usr/bin/docker.io /usr/local/bin/docker
sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker.io

in a folder create those 2 files:

Dockerfile

# FROM ubuntu:14.04
# fix for PAM issue:
FROM sequenceiq/pam:ubuntu-14.04
RUN /home/user/install.sh
EXPOSE 2222

install.sh

#!/bin/sh

dpkg-divert --local --rename --add /sbin/initctl
ln -nfs /bin/true /sbin/initctl
apt-get update
apt-get -y install openSSH-server gdbserver build-essential gdb vim
apt-get clean
rm -rf /var/lib/apt/lists/*

# we allow the root user to connect via SSH to allow debugging with VisualGDB
# setup SSH to allow root user to connect and change port
sed -i 's/Port 22/Port 2222/g' /etc/ssh/sshd_config
sed -i -e"s/^PermitRootLogin/#PermitRootLogin/" /etc/ssh/sshd_config
echo "nPermitRootLogin yesn" >> /etc/ssh/sshd_config



echo 'root:root' | chpasswd



useradd -d /home/user -m -s /bin/bash user

echo 'user:user' | chpasswd

echo 'user ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers.d/user

chmod 0440 /etc/sudoers.d/user



chown -R user /home/user

chgrp -R user /home/user



rm /home/user/install.sh

To build:
docker build –rm -t gdbimage

To run:
docker run -d -v /home/user/src:/home/user/src –net=host -p 2222:2222 gdbimage

To stop:
CONTAINER_ID=$(docker ps | grep gdbimage | awk ‘{print $1}’)
docker stop -t 1 $CONTAINER_ID

Once the docker instance is running, setup a VisualGDB project with root:password @ 127.0.0.1:2222 as connection info.
use /home/user/src/projectfolder as destination for the source.

I used a linux makefile project with the files hosted on the windows host.
The code will compile fine, and when trying to debug, gdb will fails during the -exec-run step with:

-exec-run
=thread-group-started,id="i1",pid="7085"
=thread-created,id="1",group-id="i1"

and if you hit Abort in the timeout dialog box, it then prints:

=thread-exited,id="1",group-id="i1"
=thread-group-exited,id="i1"
^error,msg="During startup program exited with code 1."

[cperthuis]

Hi,

This is the expected behavior for respecitvely login and interactive shells.
I would suggest to somehow try to run them both under the same mode, see this: http://hacktux.com/bash/bashrc/bash_profile

[cperthuis]

I found the problem, smarTTY is using .bash_profile and the ssh connection done by VisualGDB during compilation use .bashrc
DISTCC_HOSTS was only set in .bashrc for us.
