It is usually quite straightforward to get PICO-8 to run on a Raspberry Pi, but it can cause a headache at times. Double clicking the icon from the Raspbian desktop often results in nothing happening, while running from the console can give this error:
./pico8: error while loading shared libraries: libwiringPi.so: cannot open shared object file: No such file or directory
libwiringPi deals with the GPIO interface for the Raspberry Pi and PICO-8 can access this. To solve the error, you need to install libwiringPi:
$ sudo apt-get install git-core
Make a directory to store the library and change to it..
$ mkdir libraries $ cd libraries/
Clone the libwiringPi library..
$ git clone git://git.drogon.net/wiringPi
Once the files have downloaded, move the the wiringPi directory and build the library. Note that the ./ in front of build is really important.
$ cd wiringPi $ ./build
After this you can navigate back to the PICO-8 directory and launch it!
Enjoy PICO-8 on your Pi!
