<question><para>Why doesn't Cygwin tcl/tk understand Cygwin paths?</para></question>
<question><para>Why do my Tk programs not work anymore?</para></question>
<answer>
<para>The versions of Tcl/Tk distributed with Cygwin (e.g. cygtclsh80.exe,
cygwish80.exe) are not actually "Cygwin versions" of those tools.
They are built as native libraries, which means they do not understand
Cygwin mounts or symbolic links.
</para>
<para>See the entry "How do I convert between Windows and UNIX paths?"
elsewhere in this FAQ.
<para>Previous versions of Tcl/Tk distributed with Cygwin (e.g. tclsh84.exe,
wish84.exe) were not actually "Cygwin versions" of those tools.
They were built as native libraries, which means they did not understand
Cygwin mounts or symbolic links. This lead to all sorts of problems interacting
with true Cygwin programs.</para>
<para>As of February 2012, this was replaced with a version of Tcl/Tk which
uses Cygwin's POSIX APIs and X11 for GUI functionality. If you get a message
such as this when trying to start a Tk app:</para>
<screen>
Application initialization failed: couldn't connect to display ""
</screen>
<para>Then you need to start an X server, or if one is already running, set the
<literal>DISPLAY</literal> variable to the proper value. The Cygwin distribution
includes an X server; please see the <ulink url="http://x.cygwin.com/docs/ug/cygwin-x-ug.html">Cygwin/X User Guide</ulink>
for installation and startup instructions.
