I am reading ” Developing Games on the Raspbery Pi” w Lua and Love by Seth Kenlon
I am trying to use my existing raspian stretch OS rather than starting with the OS the book suggests
Lua is already installed and working
now I would like to install the Love library
I have the Love rpm downloaded
How do I install it please?
I’ll outline a couple of approaches but can’t promise either of them will work.
The .rpm I looked at contains a single executable1, love-0.7.2, which does link to liblua, but not a version available in buster:
> ldd love-0.7.2
linux-vdso.so.1 (0x7edbb000)
/usr/lib/arm-linux-gnueabihf/libarmmem-${PLATFORM}.so => /usr/lib/arm-linux-gnueabihf/libarmmem-v7l.so (0x76e33000)
libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0x76ce5000)
libgcc_s.so.1 => /lib/arm-linux-gnueabihf/libgcc_s.so.1 (0x76cb8000)
libopenal.so.1 => not found
libfreetype.so.6 => /usr/lib/arm-linux-gnueabihf/libfreetype.so.6 (0x76c15000)
libGL.so.1 => not found
libIL.so.1 => not found
liblua5.1.so.5 => not found
libmodplug.so.1 => not found
libmpg123.so.0 => not found
libSDL-1.2.so.0 => not found
libvorbisfile.so.3 => not found
libphysfs.so.1 => not found
libstdc++.so.6 => /usr/lib/arm-linux-gnueabihf/libstdc++.so.6 (0x76ace000)
libm.so.6 => /lib/arm-linux-gnueabihf/libm.so.6 (0x76a4c000)
/lib/ld-linux-armhf.so.3 (0x76f28000)
The “not found” stuff might be resolvable by searching apt packages, but there are some version mismatches. Installing close versions and symlinks have a long shot at working, but I suspect the openGL stuff will not be so easy.
You can try to build it from the source.
git clone --depth=1 https://github.com/love2d/love.git
There are directions on the github page; the first one failed for me:
> platform/unix/automagic
But with more patience you may be able to work out the problems…there are what look to be current wiki, forum, and IRC links on the github page.
- You can unpack rpms fairly easily:
rpm2cpio love-0_7_2-0.7.2-3.5.armv7hl.rpm | cpio -idv, see https://unix.stackexchange.com/questions/61283/yum-install-in-user-home-for-non-admins/61295#61295

Appendices
Appendix A – Love Newbie Start Up Guide
When beginning to write games using LÖVE, the most important parts of the API are the callbacks:
(1) love.load to do one-time setup of game,
(2) love.update to manage game’s state frame-to-frame,
(3) love.draw to render game state onto screen.
More interactive games will override additional callbacks in order to handle input from the user, and other aspects of a full-featured game. LÖVE provides default placeholders for these callbacks, which you can override inside your own code by creating your own function with the same name as the callback:
-- Load some default values for our rectangle.
function love.load()
x, y, w, h = 20, 20, 60, 20
end
-- Increase the size of the rectangle every frame.
function love.update(dt)
w = w + 1
h = h + 1
end
-- Draw a coloured rectangle.
function love.draw()
love.graphics.setColor(0, 0.4, 0.4)
love.graphics.rectangle("fill", x, y, w, h)
end
