This is not a book, though the title sounds like one (or rather a whole shelf full of good books ;-). No, it's just another page at the Tcler's Wiki. The ideas and contributions collected here needed some more indexing, and that's what this page tries to do. See also Where can I find a book about Tcl - Tcl articles.

<enter your comment here, a header with nick-name and timestamp will be insert for you> I have just downloaded the TK8.5.7 build. I am using Linux Fedora Core 10 as an OS. I configure for --enable-threads and then make test. I receive a number of errors from the tests that are run

Tests ended at Wed Sep 02 18:45:24 EDT 2009 all.tcl: Total 8788 Passed 7776 Skipped 945 Failed 67 Sourced 87 Test Files. Files with failing tests: canvText.test entry.test filebox.test font.test scrollbar.test spinbox.test text.test textDisp.test textImage.test textTag.test textWind.test unixEmbed.test unixFont.test unixSelect.test unixWm.test wm.test Number of tests skipped for each constraint:

Is this normal?
