ActiveTcl is ActiveState's quality-assured distribution of Tcl.
If you want to use ActiveTcl binary package as the Tcl/Tk libraries, please use the following configure options.
And use the followings if you need.
--with-tcllib=<libname> --with-tklib=<libname> --enable-tcltk-stubs
For example, when you install ActiveTcl-8.4.x to '/usr/local/ActiveTcl',
configure --with-tcl-dir=/usr/local/ActiveTcl/ \ --with-tk-dir=/usr/local/ActiveTcl/ \ --with-tcllib=tclstub8.4 \ --with-tklib=tkstub8.4 \ --enable-tcltk-stubs
It depends on your environment that you have to add the directory of ActiveTcl's libraries to your library path when execute Ruby/Tk. One of the way is to add entries to TCLLIBPATH environment variable, and one of the others add to LD_LIBRARY_PATH environment variable
Probably, using TCLLIBPATH is better. The value is appended at the head of Tcl's 'auto_path' variable. You can see the value of the variable by using 'Tk::AUTO_PATH.value' or 'Tk::AUTO_PATH.list'.
For example, on Linux, one of the ways is to use LD_LIBRARY_PATH environment variable.
[bash]$ LD_LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH \ ruby your-Ruby/Tk-script [bash]$ LD_LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH irb
Based on it, the Tcl interpreter changes auto_path variable's value.
Then, you'll be able to use Tcl/Tk extension libraries included in the ActiveTcl package (e.g. call TkPackage.require('BWidget'), and then, use functions/widgets of BWidget extention).
