## Building QGC on a stock CentOS:
|
||
|
|
|
||
|
|
These were the options used to setup a CentOS development system. Use it as a guideline.
|
||
|
|
|
||
|
|
Once the system is fully installed and running, we need to set it up for QGC development. First, we need to update GStreamer to a more recent version. This guide follows Alice Wonder's tips found here: https://media.librelamp.com
|
||
|
|
|
||
|
|
#### Update to a more current GStreamer
|
||
|
|
```
|
||
|
|
sudo yum install epel-release
|
||
|
|
wget http://awel.domblogger.net/7/media/x86_64/awel-media-release-7-6.noarch.rpm
|
||
|
|
sudo yum localinstall awel-media-release-7-6.noarch.rpm
|
||
|
|
sudo yum clean all
|
||
|
|
sudo yum update
|
||
|
|
sudo yum install gstreamer1*
|
||
|
|
```
|
||
|
|
Make sure these are installed (vaapi for Intel GPUs)
|
||
|
|
```
|
||
|
|
sudo yum install gstreamer1-vaapi
|
||
|
|
sudo yum install gstreamer1-libav
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Installing SDL2
|
||
|
|
|
||
|
|
SDL2 is used for joystick support.
|
||
|
|
|
||
|
|
```
|
||
|
|
sudo yum install SDL2
|
||
|
|
sudo yum install SDL2-devel
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Installing Qt
|
||
|
|
|
||
|
|
mkdir ~/devel
|
||
|
|
cd ~/devel
|
||
|
|
|
||
|
|
Install Qt 5.12.4 from the Qt installation script which can be downloaded [here](https://www.qt.io/download-thank-you?os=linux&hsLang=en). Once downloaded, make it executable and run it:
|
||
|
|
```
|
||
|
|
chmod +x qt-unified-linux-x64-3.1.1-online.run
|
||
|
|
./qt-unified-linux-x64-3.1.1-online.run
|
||
|
|
```
|
||
|
|
|
||
|
|
Select the following options and install it under ~/devel/Qt
|
||
|
|
|
||
|
|
#### Clone and Build QGC
|
||
|
|
```
|
||
|
|
git clone --recursive https://github.com/mavlink/qgroundcontrol.git
|
||
|
|
mkdir build
|
||
|
|
cd build
|
||
|
|
```
|
||
|
|
For a debug/test build:
|
||
|
|
```
|
||
|
|
../Qt/5.12.4/gcc_64/bin/qmake ../qgroundcontrol/qgroundcontrol.pro -spec linux-g++ CONFIG+=debug
|
||
|
|
```
|
||
|
|
For a release build:
|
||
|
|
```
|
||
|
|
../Qt/5.12.4/gcc_64/bin/qmake ../qgroundcontrol/qgroundcontrol.pro spec linux-g++ CONFIG+=qtquickcompiler
|
||
|
|
```
|
||
|
|
Build it: (use the appropriate number of CPU cores for you machine)
|
||
|
|
```
|
||
|
|
make -j32
|
||
|
|
```
|
||
|
|
|
||
|
|
You can alternativelly launch QtCreator (found under `~/devel/Qt/Tools/QtCreator/bin/qtcreator`), load the `qgroundcontro.pro` project and build/debug from within its IDE.
|
||
|
|
|
||
|
|
#### Running QGC
|
||
|
|
Before launching QGC, you need to make sure the current user has access to the dialout group (serial port access permission):
|
||
|
|
```
|
||
|
|
sudo usermod -a -G dialout $USER
|
||
|
|
```
