Problems installing QGC on Ubuntu 14.04


I’ve tried several times to install QGC on Ubuntu 14.04 in the last hours but it doesn’t work. I installed Qt Creator with Qt 5.11.3 as mentioned in the installationguide and was able to build the project without errors but a lot of warnings - something like … qgeomapprivate is already a friend… but i can’t see these warnings anymore.

I followed the instructions and installed all the dependencies.

If i click on “Run” i get this “Application Output”:

10:00:48: Starting /home/stephan/simulation/build-qgroundcontrol-Desktop_Qt_5_11_3_GCC_64bit-Debug/debug/QGroundControl…
QML debugging is enabled. Only use this in a safe environment.
System reported locale: QLocale(English, Latin, UnitedStates) “en_US”

10:00:49: /home/stephan/simulation/build-qgroundcontrol-Desktop_Qt_5_11_3_GCC_64bit-Debug/debug/QGroundControl exited with code 127

and this “Compile Output”:

10:00:48: Running steps for project qgroundcontrol…
10:00:48: Configuration unchanged, skipping qmake step.
10:00:48: Starting: “/usr/bin/make”
make: Nothing to be done for `first’.
10:00:48: The process “/usr/bin/make” exited normally.

and “General Messages”:

I’m not sure if i can install the latest stable version on Ubuntu 14.04 or which version i should use instead.


I see this runtime error: undefined symbol: FT_Get_Font_Format

And found this:

I suggest check that you have all the Qt libraries installed that are potentially needed.

And on another note, Ubuntu 14.04 will be end-of-lifed April 2019, so you might as well update (if possible).
