“Raspberry Pi" is a trademark of the Raspberry Pi Foundation.

sudo apt-get install libwxgtk3.0-dev
sudo apt-get install libusb-1.0-0-dev

The wxWidgets library, libwxgtk3.0-dev, is only needed if Rocview should be build too. (Approximately total build time is < 10 minutes under Jessie on a Raspberry Pi 3)

Pre-build packages (nightly build) can be found here:

• http://rocrail.net/software/rocrail-snapshot/

wget http://rocrail.net/software/rocrail-snapshot/rocrail-xxxxx-raspbian-stretch-armhf.deb

sudo apt install rocrail-xxxxx-raspbian-stretch-armhf.deb

Note: the “xxxxx” should be replaced with the wanted revision.

Attention ! You need the web-address and password distributed by Rob !

git clone ... (http://forum.rocrail.net/viewtopic.php?f=7&t=10092)

cd ~/Rocrail 
make fromtar 

Note: Use the -j 4 make option to use all for cores of the Raspberry Pi version 2.

If wxWidgets is not installed the build process will end at the start of compiling Rocview.
Just ignore the errors if you are interested in the Rocrail Server only.

With the following command the sources can be updated:

cd ~/Rocrail 
git reset --hard
git pull

Use the following command to rebuild Rocrail:

cd ~/Rocrail 
make fromtar

Or to rebuild the Rocrail Server only:

cd ~/Rocrail 
make fromtar server

sudo make install 

A build can be shared by creating an install package:

cd rocrail 
./mkdeb.sh wheezy armhf 

• Install pre-build package on a RasPi 3
  
• Rocrail auf einem RasPi installieren (German only)
  

Open the RasPi Configuration utility in a terminal:

sudo raspi-config
