Relocatable Ruby executable

[Asfand Yar Qazi]

Hi,

How can I create a relocatable Ruby executable? Meaning, that I can
distribute a copy of it along with the modules I need with a binary app I am
embedding Ruby into. I'm considering both actually programatically embedding
Ruby into my app using libruby.a or whatever, as well as making my app an
extension library run by the Ruby executable - if you could give details of
both, I'd be grateful.

Thanks

Are you aware of rubyscript2exe? It packages the interpreter + libraries
you require + your main script file. I've been very happy with it.

This is for the ruby extension approach, but not the embedding approach.

I -think- on Windows the ruby interpreter semiautomagically sets up the pat=
hs=20
it needs relative to the path where ruby.exe that was run is located, so if=
=20
you can go without the aesthetics and compactness of rubyscript2exe, you=20
should be able to safely get away with distributing your ruby directory alo=
ng=20
in the application's distribution somewhere.

I don't think rubyscript2exe is feasible for a game - think something like
Quake 3 here. But I could be wrong. I would rather have more control over
the files I distribute, that way I can create patches that replace small files
easily - rubyscript2exe I assume bundles everything into a single file that is
unpacked at runtime.

I'll have a look at it though...

But what about when embedding Ruby in my app? How do I handle module paths then?

Thanks

After initializing the interpreter you can use rb_eval_string() to
execute arbitrary Ruby statements and, for example, setup your library
path by executing (from memory):

rb_eval_string( "$:.clear" );
rb_eval_string( "$: << "my library path" );
