Thanks very much; now I know how to read Ruby error messages (I'm still a rank beginner w/ Ruby). I set the env variable TCL_LIBRARY, and now I'm getting the following error: ------------------------------------------------------- C:\Ruby>ruby sample\tkhello.rb LoadLibraryExA: c:\RUBY\LIB\tcltklib83.dll /cygdrive/c/RUBY/LIB/tcltklib.rb:7:in `require': 1157: One of the library files needed to run this application cannot be found. - /cygdrive/c/RUBY/LIB/tcltklb83.dll (LoadError) from /cygdrive/c/RUBY/LIB/tcltklib.rb:7 from /cygdrive/c/RUBY/LIB/tk.rb:7:in `require' from /cygdrive/c/RUBY/LIB/tk.rb:7 from sample\tkhello.rb:1:in `require' from sample\tkhello.rb:1 -------------------------------------------------------- I'm not sure what the problem is. Here's a directory listing from Ruby\lib: C:\Ruby\lib>dir tc* /b tcltk.rb tcltklib.rb tcltklib76.dll tcltklib81.dll tcltklib82.dll tcltklib83.dll Am I missing something? Looks to me like tcltklib83.dll is there, so I'm assuming the error message means it's having trouble finding Tk...? My env vars are set as follows: set TCL_LIBRARY=c:\Python20\tcl\tcl8.3 set TK_LIBRARY=c:\Python20\tcl\tk8.3 SET RUBYLIB=C:\RUBY\LIB Any suggestions?
