Library sdl (cannot load such file)

Why i have always:

/.rvm/rubies/ruby-1.9.3-p286/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in
`require’: cannot load such file – sdl (LoadError)

i’ve already made:
$ sudo apt-get install libsdl1.2-dev (libsdl1.2-dev is already the
newest version.)
and
$ sudo gem install -r rubysdl and
and
$sudo apt-get install libsdl-ruby (libsdl-ruby is already the newest
version.)
and even: $ rvm remove 1.9.3 and $ rvm install 1.9.3

But always this “cannot load such file”!!! Whyyy ? What else does it
want ?

Have you tried running gem without sudo?

I do not use rvm, and I try to stay as clear as possible from
gems. Your problem is probably related to one of these two
technologies, so I really can’t give you a solution. But if you are
using Linux, I can suggest a way to shed some light.

Say your script is called script.rb Run it like this:

strace -eopen ruby script.rb 2>/tmp/output

This command dumps a line in /tmp/output for each file that is opened,
or fails to be opened.

Your error message indicates that you cannot find file sdl.rb. Thus,
do:

grep sdl.rb /tmp/output

you will see where the Ruby interpreter looks for your file. The
places will not include the directory where the file included in the
gem has been installed.

From then on, it really depends on what you find out. It may be that
you were running another instance of the ruby interpreter when you
loaded the gem, for example.

You need to research a bit more, it seems.

Hey, can you post more information? Do you have any file that is requiring
sdl?

I have written lots of code that requires sdl, but I compile both Ruby
and the Sdl library. My examples would do you no good.

Also, you should update your Ruby to 1.9.3-p392. :stuck_out_tongue:

$ ruby -v
ruby 2.0.0dev (2013-01-02 trunk 38676) [x86_64-linux]

:-/

Well now search for where your sdl.rb was actually installed:

sudo find / -name sdl.rb

(might take a bit of time)
