Hi there, I really need to be able to use tk on my linux box, but I get an error: require “tk” =\> test.rb:1:in `require’: No such file to load – tk (LoadError) I can’t figure out how to solve this, since I got tk installed, and i works out just fine on my window box. Anyone who can help? Thanks in advance. ---

I’m afraid I did something wrong. When i enter the last line in step 3, I got this error: ruby: No such file or directory – extconf.rb (LoadError) Some things that may have caused the error: Maybe I’ve been in the wrong directory? (Which one is the correct one?) Maybe I don’t get the part about extconf.rb. Is it an existing file, or shall I create it? If so, where do I put it and what should it contain? I’m kind of new to Linux, so I don’t get most of the stuff yet. 2006/3/25, Gerardo S. Gómez Garrido [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid): ---

Yes I saw it but I don’t quite understand. For one thing, I don’t seem to have a directory called ext/tcltklib. I can’t find it and neither can my search function. I don’t have a directory called /usr/swf either. 2006/3/29, Gerardo S. Gómez Garrido [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid): ---

You need Ruby’s source code, ext/tcltklib is there. You need Tcl/Tk’s header files and libraries. Depending on your Linux distribution, you’d need a \*-devel and a \*-lib package or something similar. Then substitute /usr/sfw with the path where those files are installed. Don’t forget to read ext/tcltklib/README.1st ---

From the same conversation: # cd ext/tcltklib # ruby extconf.rb --with-tcl-include=/usr/sfw/include # make && make install Of course, /usr/swf/include should point to where your Tcl headers are installed. Everything will be clear for you when you read the README file inside ext/tcltklib. 2006/3/28, Jeppe J.

I’ll take that I also will need the source for \*-devel to get the headers? Where can I find this? A search on google only gave me a lot of packages. 2006/3/29, Gerardo S. Gómez Garrido [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid): ---

If you extracted source codes of Ruby 1.8.4, there is not ‘ext/tcltklib’. ‘ext/tcltklib’ and ‘ext/tk’ were unified to ‘ext/tk’. Please check READMEs on ‘ext/tk’.
