Running FreeBASIC on Raspberry Pi

FreeBASIC is a pretty nifty cross-platform BASIC compiler. It uses a Microsoft-like syntax, has an active user and developer base, and is quite fast. Building the latest version on a Raspberry Pi is a bit of a challenge, though.

Part of the problem is that FreeBASIC is mostly written in FreeBASIC, so you need a working compiler to bootstrap the latest version. The following steps worked for me:

  1. Install some necessary packages:
    sudo apt-get install build-essential libncurses5-dev libffi-dev libgl1-mesa-dev libx11-dev libxext-dev libxrender-dev libxrandr-dev libxpm-dev ncurses-doc libxcb-doc libxext-doc libgpm-dev git libcunit1 libcunit1-dev libcunit1-doc

    (You don’t really have to include the cunit packages; they’re only needed if you run tests before installation.)

  2. Download a nightly binary from Sebastian’s server: http://users.freebasic-portal.de/stw/builds/linux-armv6-rpi/  and install it:
    unzip fbc_linux_armv6_rpi_version.zip
    cd fbc_linux_armv6_rpi/
    chmod +x install.sh
    sudo ./install.sh -i

    Don’t delete the installation folder just yet.

  3. Grab the latest version of the source from github:
    cd
    git clone https://github.com/freebasic/fbc.git

    Change directory to the new FreeBASIC source folder (cd fbc), and type make. (or, on a Raspberry Pi 2, make -j4 to use all the cores …). After a while (in my tests, about 52 minutes on a 512 MB Raspberry Pi, or around 6½ minutes [!] on a Raspberry Pi 2), it should finish. If there’s a bin/fbc file, the compilation worked!

  4. Before you install the new compiler, uninstall the old one: change directory to the fbc_linux_armv6_rpi folder, and type:
    sudo ./install.sh -u
  5. Once that’s done, go back to the new fbc folder, and type:
    sudo make install

And you’re done! You can delete the fbc_linux_armv6_rpi folder now. If you don’t mind it taking up space, keep the fbc folder to allow you a quick rebuild of the latest version of the compiler with:

cd fbc
git pull
make
sudo make install

Note that this will build a native armv7l compiler on a Raspberry Pi 2, and an armv6l one on a Raspberry Pi. This means you can’t run binaries you built on a Raspberry Pi 2 on a Raspberry Pi (you’ll get an Illegal Instruction error), but you should be able to run ones built on a Raspberry Pi on a Raspberry Pi 2. Binary compatibility is overrated, anyway …
