There is now a quicker method to get ModesDeco2 running on a Raspberry Pi if you haven't already installed dump1090. See Post #5 for details.You may want to check this post for some tips that are applicable to the new post

Started a separate thread to avoid mixing up with thread on development. Hope it helps.
I wanted to try ModeSDeco2 on a Pi but couldn't find the instructions. I'm sure they were here on the forum at some time. Anyway just running "modesdeco2" gives an "sdr" error. That made me realise what I needed to install.
Essentially we need the sdr libraries used by other ModeS software on Linux.
Assuming you have the Pi set up with Raspian and can connect to it remotely via Putty, follow David Taylor's instructions from item #5 for "Preparing the Raspberry Pi" at
http://www.satsignal.eu/raspberry-pi/dump1090.html.
This was written to get dump1090 working but also valid for ModeSDeco2.
It is up to you whether you want to calibrate the dongle (I never have) but stop at the instruction that says "Now download the latest release dump1090 application source code."
Tips:
- I would ignore the comment about not upgrading
- Use Ctrl-C or right-click Copy to get the text into the clipboard, and then if you use PuTTY you can right-click on the text area of the terminal session to enter the command into the Raspberry Pi. Avoids the need for typing strange commands!
- You probably will need to replace the default DVB driver so follow the linkin the instructions. Nano is a text editor and you can copy the three lines using the same Ctrl-C and then right click in Linux to copy them. To save and close nano , use Ctrl-O to save and Ctrl-X to exit. Then reboot.
The system is now ready to install and run Modesdeco2.
I use WinSCP to copy files to and from the Pi:
http://winscp.net/eng/index.php. You get a drag and drop file manager interface.
Copy the version of modesdeco2 for your version of the Pi from the PC to the Pi.
In PUTTY type
ls
You should see your
modesdeco2_rpi_yyyymmdd.tgz file in red text. Select it with the mouse (run the mouse cursor over the filename to hightlight it, type
tar -xvf
at the command line and then right click to copy the filename
tar -xvf modesdeco2_rpi_yyyymmdd.tgz
Hit return and the tgz file will be uncompressed.
Do a directory listing (type "ls") and you should see
modesdeco2 in green text (means it is executable). Just typing "modesdeco2" won't work - you will need to type
./modesdeco2
Add the command line option you require.
You can avoid retyping long command lines by using the up and down arrows to fetch
previous commands

.
This has installed modesdeco2 in the /home/pi directory.
Additional tips:
- If you add a basestation.sqb file to this directory, you don't need to specify the location BUT be careful with the naming - in Linux, BaseStation.sqb and basestation.sqb are two different files. It seesm there is already software to read the sqb file installed.
- If you add a directory called "silos"(note you can create it using WinScp, or using mkdir command depending on your knowledge) to hold all the .bmp files, the "path/to" will be /home/pi/silos
Edit: Comments and improvements welcome!
Not least how do you keep it running when PUTTY is closed? Tried "&" but not successful
