The latest prodUCtion and alpha releases are available from the modules/by-authors/Nick_Ing-Simmons/ Directory on the CPAN. If building from source code you will need a made and installed perl (Perl 5.005 or later being an Excellent choice), a recent MakeMaker and the Tk kit. To oBTain all of these (as well as several other modules that sophisticated Tk programs now rely on) visit a CPAN FTP site. CPAN (the Comprehensive Perl Archive Network) and what you need to get from it, is discussed in more detail in the next question.
ActiveState Corporation has taken over the chore of maintaining what originated as Gurusamy Sarathy's binary distribution for WinNT, Win95, Win98, and Win2000. [Mention license considerations here?] This is what you must do to "use Tk" with ActivePerl:
1. Download and install version 1.1 or greater of the Windows Installer (while the installation claims a reboot is necessary, Cameron Laird found it not to be so for WinNT);
2. Download the ActivePerl 618 distribution:
3. From Windows EXPlorer, activate the distribution just downloaded [what's the command-line way?]. This installs ActivePerl;
4. From a command line, invoke ppm install Tk;
5. At this point, you can perl -e "use Tk" from a command line, and you're ready to code Perl/Tk source.
Jon Bjornstad gives more details about the process, some of which you might particularly need if you work with ActivePerl before release 618.
(While the next question treats CPAN in detail, the remainder of this answer points out some non CPAN resources, as well as some historical resources.)
Tk-b8: The Tk-b8 kit remains on CPAN since it was compatible with the widely distributed and installed Perl (5.001m) Binaries
A pre-compiled binary distribution of Perl5.001m with Tk-b8 for Linux is available from: Australia (please be patient and only try during off hours) ftp://syd.dit.csiro.au/pub/perl5/local/perl5.001m+Tk-b8-Linux-ELF.tar.gz
It unpacks into /usr/local. You need to have ELF running and to have the ELF X11 libraries (please be patient and only try during off hours).
