How can I use Tk with Ruby?

I tried the statement:
require 'tk'

But it gives me this error:
LoadError: no such file to load -- tk

Do I have to install tk for it to work?

Ok. I dowloaded tk. Where do I put the file?


I put it in the ruby folder. I typed ./configure, then make but got this error:
compiling readline

- seems you don't have the proper headers. Do you run on mac?
- tk work with tcl, do you have tcl installed?

best regards

Yeah, I'm on a mac. Where can I get the proper headers?

Where can I get tcl from?



Thanks.

Thanks.

usualy they come with tcl and tk but some come with system libs.

same place you get tk.

Sorry, I have no experience with this on mac, I don't think that my answers could help in this case.

best regards

Ok, thanks.


How do I install tk/tcl after I have downloaded it?

Few years ago I use this for a multiplatform project and I was happy:

PS: seems to be a problem with readline and ruby 1.8.6 on mac.
