Let’s start with the ubiquitous Hello World with a little extra, in C++ of course. Your host system should now be ready to build a Raspberry Pi program.

Work back through the installation of the build tools if you get an error.
COMPILING CODE PLUS
To test if everything is working enter the following line, which should report the version of the G++ compiler installed, plus a lot of other information: arm-linux-gnueabihf-g++ -v Be sure to get the dash at the end of the string. Make a note somewhere of the ARM architecture designation, arm-linux-gnueabihf-, because it is used as a prefix to distinguish the ARM tools from the host system tools.

The third installs a version of the gdb debugging tool that works with target systems regardless of the processor architecture. The second installs the C and C++ compiler and build tools for the Pi’s ARM processor. The first line installs the general build tools.
COMPILING CODE INSTALL
Sudo apt-get install g++-arm-linux-gnueabihf From the command line run the following: sudo apt-get install build-essential The first step is to install the development tools on the desktop, or host system.

Take care if you use an earlier distribution since the ARM development libraries may not be the ones used on the Pi. This process should work okay on Linux and something similar can be done under Windows. I first setup the desktop for cross-development and then replicated the steps on the laptop to verify the process. I’m using Ubuntu 14.04 on my desktop and 15.04 on my laptop. I’ve been meaning to try this for a while and after the first pass on the Pi lidar project decided that the time was now. More recently for my 2013 NASA Sample Return Robot Competition entry I debugged my rovers, running XP on ITX PCs, over WiFi.Ĭross-development is pretty natural approach for a Pi since it’s how Raspian gets built.
COMPILING CODE SOFTWARE
In the late 80s I used 80×86 based PCs to develop software for a STD bus system that used an 80286 processor. You’ve already done it if you’ve compiled for the Arduino on your desktop. This’ll let you develop and debug from in the comfort of your desktop. An added advantage is when you put that Pi in a robot you can debug over a wireless link.Ĭross System Development Rud’s SRR Rover Trying to Dig Under BlockĬross-development is actually fairly common. This means loading a Pi ARM toolchain on your desktop and a debugging server on the Pi. We’re going to walk through setting up your desktop and a Pi to do this. My usual comment is, “dirty word”, literally.Ĭross-developing on your desktop is a very workable solution. Even then it’s frustrating to switch back and forth between the desktop and the Pi because there is always something on the other system that you need. Then it all gets wiped when you install a new distribution, like the recent change from Wheezy to Jessie. When developing on a Raspberry Pi, you leave all these creature comforts behind unless you spend the time to configure the Pi to your liking. Your editor highlights syntax in your favorite colors already. If you need a calculator, it’s right there to run. If you want to search the web, the browser is just an alt-tab away. On your desktop everything is at your fingertips. You’ve already got your favorite development tools and references setup or installed and it’s a pain when you’re trying to work on an unfamiliar, or simply uncustomized, system. Sometimes there’s just no place like your desktop.
