Hi,

I’ve been trying to get Tk to work with Ruby 1.9.1 on OpenSuSE 11.1  
(Tcl/Tk 8.5), with no success so far. I have manually fixed the config  
as suggested in ext/tk/README.1st. (There has been a warning about  
incompatible pthread settings between Ruby and Tk, but trying to disable  
pthread support failed the build for me.) The build works, but when  
trying to use Tk, I get

/home/patrick/applications/ruby/ruby1.9.1/lib/ruby/1.9.1/tk.rb:29:in  
`initialize': out of stack space (infinite loop?) (RuntimeError) from /home/patrick/applications/ruby/ruby1.9.1/lib/ruby/1.9.1/tk.rb:29:in`initialize’  
from  
/home/patrick/applications/ruby/ruby1.9.1/lib/ruby/1.9.1/tk.rb:1168:in  
`new' from /home/patrick/applications/ruby/ruby1.9.1/lib/ruby/1.9.1/tk.rb:1168:in`block in module:TkCore’

With the 1.8.7 Ruby from the SuSE repository everything works fine. Any  
hints?

Best regards,  
Patrick
