This was originally out of the running because it uses the closed source FMOD library for sound output on Windows. Releasing commercial software on Windows would require getting a license for FMOD.

However, since everything else is horrid beyond comprehension and this is just gem install gosu we’ll use it for now.

.. and examples work out of the box: /usr/lib/ruby/gems/1.8/gems/gosu-0.7.25/examples

crap I should have ignored that.. it’s for an older failed library.

smart install libsdl-devel libSDL_mixer-devel libboost-devel libSDL_ttf-devel libmesaglut3-devel libSDL_gfx-devel libSDL_image-devel

gem install gosu
gem install ruby-opengl

Solved: I ended up switching from Unity Linux to Lubuntu.

OpenGL ∞

sudo gem install ruby-opengl
freeglut3-dev

rake? mkrf?

sudo apt-get install ruby rdoc ri ruby1.8-dev

(RDoc)

Hrm, I don’t exactly remember what I did, but it was pretty easy to get things working.

2010-11-10 – (version not recorded) ∞

I began with:

\sudo  \apt-get install libsdl1.2-dev pkg-config g++ libboost-dev libsdl-mixer1.2-dev ... and more, bah

Recommended, I did this:

\sudo  \apt-get  install g++ libgl1-mesa-dev libpango1.0-dev libboost-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev ruby1.8-dev
\sudo  \gem  install gosu

Somehow, scripts began to work when I’m in ~ when I run them. This wasn’t the case earlier (they were broken everywhere). What the hell.

Unsolved: Why do I have to be in ~ or in the tutorials directory to run scripts?
