Repos:

# get the sources for mavlink from git, and build it

git clone https://github.com/mavlink/mavlink

cd mavlink

mkdir build

cd  build

cmake ..   #<----------------------------correction from qmake ..

make configure  

make

sudo make install

# if you get any errors (repo changes always), in building mavlink crap,

just forget it and, https://github.com/downloads/mavlink/mavlink/mavlink-1.0.9.deb

and install it with package manager. Right click, open with 'package|system|* whatever installer'

then continue with the procedure...

#get the sources for qgroundcontrol, and build ir

git clone git://github.com/mavlink/qgroundcontrol.git

cd qgroundcontrol

git clone http://github.com/LorenzMeier/qupgrade/

qmake qgroundcontrol.pro

make

# If you get linker errors as: Geometry::set*Array and View::checkErrors type of..

#apply the attached patch. PATCH.TXT obsolette

#apply this patch: patch2.txt

# fixes for linkage errors and FlightModes current PWM value

#Read here how to apply a patch file to a tree (Linux): howto-patch

#then continue

make clean && make

# it should build without errors

# copy the qml/ resources folder where the qgroundcontrol binary was made

cp -r qml /release

cd release

# start qground control application

./qgroundcontol

#select APM. Now let's connect the USB cable from PC to the 3DR arducopter 2.5/6

#open another terminal, and clean the kernel message log

sudo dmesg -c  # clean the log

# insert the usb cable from the PC to the APM 2.5(6). (for telemetry connection radio 3DR scroll a bit down)

sudo dmesg -c    # check (visually in the output) the device tty* which was installed... ttyACM0

The mavlink build manually, above did not do it's magic, so on top of it, I installed the Debian binary package.

Download @ https://github.com/mavlink/mavlink/downloads the: mavlink-1.0.9.deb

in to your ~/Downloads folder. Open a file browser,  right-click it and Open it

with Ubuntu Software Centre (or Debian installer). Install. Ignore all the messages

about the stability of the package. After install it might say INSTALL again. Just exit the

Installer, if you have seen the progress bar going to the end.

Close the connection to APM. Unplug the USB.Close the qgroundcontrol application.

Power the APM from a USB power  or from the battery (don't forget the safety procedures).

Make sure the radio (s) TX/RX are plugged, RX on APM, ant TX on the USB.

Look here for details: http://code.google.com/p/ardupilot-mega/wiki/3DRadio

Check the dmesg when you plug the USB radio module. On my computer it assigns it to ttyUSB0 device.

Start qgroundcontrol. Change the device by clicking on the [ttyACM0] (previous your device) square

(right-top corner) to ttyUSB0 (new dmesg detected device), and Bit rate to 57600. Press CONNECT.

#The patch has been updated to add current PWM feature to flight modes page:  (Nov/23/2013)

-re-edited on Nov 22 (added the radio 3DR mavlink guideline)

-re-edited on Nov 23 (added current PWM on flight modes page to tune up the PWM's)
