			* You can manually configurate GDB by modifying values in configuration screen:
			** The '''Debugger''' path is automatically entered by Buildroot. It must be a GDB compiled to debug on ARM platforms.
			** The '''Local executable''' must be compiled against Qt Embedded for ARM and will be used by the host GDB and transfered to the remote system for GDB server.
			** The '''Sysroot''' is the remote system root path in host. GDB needs it to have access to all system headers and libraries.

			* When you click on '''OK''', the GDB server and host start and you can debug the remote application.

			=== SSH DSA keys ===
			* SSH is used to transfer the file to debug to the remote system and to launch the remote GDB server.
			* If you choose to use GDB with Qt Creator in Buildroot, DSA keys will be automatically generated for SSH on your host PC and installed in the remote system rootfs.
			* The host public and private keys are installed in ''buildroot/output/host/etc/ssh/''
			* You can also generate your own keys and use them to debug the remote application but then you have to:
			** Put the public key in the remote system rootfs' authorized-keys file: ''buildroot/output/target/root/.ssh/authorized_keys''.
			** Change the '''PRIVATE_KEY_PATH''' variable in '''gdb_server_script''': ''buildroot/output/host/etc/Nokia/gdb_server_script''.

Qt Creator

New page

== Introduction ==

This page will explain how to automatically install and configure Qt Creator for Armadeus boards.
It will also describe the way to use GDB in Qt Creator for remote applications.

== Installation ==

=== Buildroot ===

* Qt Creator is now fully integrated in Armadeus Buildroot. To install it, go in your project's BSP directory and use the command:

<pre class="host">
[armadeus]$ make menuconfig
</pre>

<pre class="config">
[*] Host utilities --->
[*] host qtcreator --->
--- host qtcreator
[ ] GDB for QtCreator --->
</pre>

* If you want to use GDB in QtCreator for remote applications:

<pre class="config">
[*] Host utilities --->
[*] host qtcreator --->
--- host qtcreator
[*] GDB for QtCreator --->
--- GDB for QtCreator
(192.168.0.208) GDB server IP address
(5600) GDB server port
(/srv/developpements/armadeus_4-1/processManager/bin/processManager) Local executable
(/usr/bin/processManager) Remote executable path on system
(-qws) Remote executable arguments
</pre>

The ''GDB server IP address'', the ''GDB server port'', the ''Local executable'' and the ''Remote executable path on system'' must be filled.
The ''Remote executable arguments'' are facultatives.

* Then you can build Qt Creator:
<pre class="host">
[armadeus]$ make
</pre>

=== Manual configuration ===

* The QtCreator's configuration files are automatically generated in ''buildroot/output/host/etc/Nokia'': '''QtCreator.ini''' and '''toolChains.xml'''.
** Qt Embedded and g++ toolchain for ARM are automatically entered in Qt Creator's configuration.

* '''GDB server script''' can be manually modified. Is is located in ''buildroot/output/host/etc/Nokia/gdb_server_script''.
This script transfers the executable to debug to the remote system and launch the remote '''GDB server'''.
The following variables can be changed according to the user needs: '''IP_ADDR''', '''EXEC_ARGUMENTS''', '''PRIVATE_KEY_PATH''', '''LOCAL_EXEC_PATH''', '''REMOTE_EXEC_PATH'''.

== Usage ==

* QtCreator's binary is located in ''buildroot/output/host/usr/bin/qtcreator''.

* Qt and toolchains can be respectively configured in the menu ''Tools --> Options --> Qt4 / Tool Chains''.

=== Remote debugger ===

When in Qt Creator, go in the menu ''Debug --> Start Debugging --> Start and Attach to Remote Application''.
