Hello all,

I previously used Tk with Python, now I wanted to write some simple Tk  
program in Ruby  
I am not 100% familiar with the build process of Ruby sources on my  
Linux box, on configure you usually see what header/tools has been found  
in the system and the Makefile is generated  
I can imagine that this search process affects what Ruby libraries gets  
build in the process later. Thus I installed tcl with configure  
–prefix=/some-hidden-directory and tk sources with  
configure --prefix=/usr/local/bin  
make  
make install  
So the tk libraries should be included in the INC/LIB search path  
when Ruby’s configure is running(?)  
Then I got Ruby 1.8.3 sources and configured-make-ed them.

rb(main):004:0\* require “tk”  
LoadError: No such file to load – tcltklib  
from /pool/installed/ruby//lib/ruby/1.8/tk.rb:7:in `require' from /pool/installed/ruby//lib/ruby/1.8/tk.rb:7 from (irb):4:in`require’  
from (irb):4  
irb(main):005:0\>

this is the error message  
I tried to find “tcltklib” without success  
find /pool/installed -iname “tcltklib”  
find /usr/local/ -iname “tcltklib”  
find /usr/lib/ -iname “tcltklib”  
nothing …

I notieced the double // in the path

irb(main):024:0\> $:.map! {|path| path.sub("//", “/”)}

irb(main):029:0\* require ‘tk’  
=\> false

still nothing, I am running out of ideas 🙂  
where is the chain broken, thankfull for all suggestions

Regards ,Daniel

Probably, ‘configure’ failed to find Tcl/Tk headers and libraries.  
Please read ext/tcltklib/README.1st on your ruby-1.8.3 source tree,  
and give options to tell the paths of Tcl/Tk headers and libraries.

# Or fail to pthread check.
