For other ways to obtain Tcl/Tk (such as binary distributions), see the main Tcl/Tk page.
Each of these files is explained in more detail below.
Other versions of the source distributions are available at SourceForge.
The source releases include make files for Windows, Unix and Xcode project files for Mac OS X.
Once you've retrieved the sources, click below for instructions on how to configure, compile, and install Tcl/Tk.
Unix (including Mac OS X)
You'll want both Tcl and Tk sources; choose the gzipped tar format. The files listed under the Windows sources contain the same information but are in ZIP format.
Gzip'ed Tar Files
Extract gzip'ed archives with this UNIX command line:
gunzip < file.tar.gz | tar xvf -
If you have downloaded the Unix version of these files, there is no need to also download these versions since these files are identical but in ZIP format instead of compressed tar.
There are many Web sites around the world that mirror Tcl and Tk releases, plus additional Tcl information. You may find it more convenient to download Tcl/Tk from a mirror site that is close to you.
