How to Install (Developers)¶

Note

If you’d like to contribute to the development of the ROS Qt Creator Plug-in, you are considered a developer, please follow the following instructions.

Installation¶

Installation Procedure for Ubuntu 14.04¶

sudo add-apt-repository ppa:levi-armstrong/qt-libraries-trusty
sudo add-apt-repository ppa:levi-armstrong/ppa
sudo apt-get update && sudo apt-get install qt57creator-plugin-ros libqtermwidget57-0-dev

Installation Procedure for Ubuntu 16.04¶

sudo add-apt-repository ppa:levi-armstrong/ppa
sudo apt-get update && sudo apt-get install qt57creator-plugin-ros libqtermwidget57-0-dev

Configure system to use the new version of Qt¶

After installation you need to tell qtchooser where to find this install. Replace the two lines in the file below with the location to the local version shown below. Make sure to change username and version in the file path to match your system.

File:

sudo gedit /usr/lib/x86_64-linux-gnu/qt-default/qtchooser/default.conf

File content:

/opt/qt57/bin
/opt/qt57/lib

Run ROS Qt Creator setup script¶

Clone your fork of the repository.

git clone -b master https://github.com/<username>/ros_qtc_plugins.git

Next in a terminal, navigate into the repository directory and execute the command below.
```
bash setup.sh -d
```

Note

Instruction 2 can can be repeated to get the latest updates for Qt Creator source. The developer must manually update there fork to get the latest version of ros_qtc_plugins.

Testing Plugin¶

Execute the command below or launch using the desktop launcher.
```
qtcreator
```
To verify that the plugin exist, goto File>New File or Project>Projects>Other Project>ROS Workspace. If the ROS Workspace is present then everything built correctly and is ready for development and testing.

Debug issues with Plugin¶

Next in a terminal, navigate to the repository ros_qtc_plugin and execute the command below.
```
bash setup.sh -di
```
Now launch qtcreator using gdb as shown below and after the plugin segfaults post the trace back in the active/new issue.
```
gdb <local>/qt-creator-build/bin/qtcreator
(gdb) run
```
After error:
```
(gdb) bt
```
