That's correct; the only external dependency is expat
(see previous message).

Already done (see previous message), fix is now in CVS.

I have no idea what the official package name is supposed to be,
or if it even has one...  Steve?

It's basically in maintenance mode right now.
I intend to support it as far as bug-fixes and
upgrades to new versions of Tcl and/or expat go,
but don't have time to add all the new features
implemented in the mainline TclDOM codebase.
Expect it to stay at version 2.0 for the foreseeable
future :-)

The second one is OK to ignore (I just missed a CONST84
in the Tcl 8.4 constification process), but the first one
might be a problem -- the function signature for doctype
handlers changed between expat 1.2 and 1.95.  (That said,
I've been using tcldompro with expat 1.95 for quite a while
now without seeing any problems.  Then again I rarely use
<!DOCTYPE ...> declarations, so YMMV.)

I've just committed a new version of tdpExpat.c and other
relevant files to make it compile cleanly with expat 1.95.

That's correct; the tcldom/src codebase is independant of
the rest of TclXML / TclDOM.  (It does share the test suite
and documentation, although those have diverged considerably.)

[Tclxml-users] Problems building compiled tcldom on linux

From: Forest W <lyr...@ti...> - 2003-03-27 19:45:29

Now that I have tclxml building, I am trying to build a compiled
implementation of tcldom on red hat linux 7.3.

=46ollowing the instructions in the README file, I am able to configure,
make, and install from the tcldom-2.6 directory.  However, the libxml2
build fails, as does the TclDOMPro build.

Within the tcldom/src-libxml2 directory, the configure script appears
to run okay, finding my tcl and libxml2 directories in the places I
specify.  However, running make results in a mess of errors, beginning
with this one:

   In file included from tcldom-libxml2.c:21:
   tcldom-libxml2.h:23:20: tcldom.h: No such file or directory

tcldom.h exists in the tcldom directory (which is the parent of my
build dir) and in ${prefix}/include, but it isn't being found.  This
occurs even when I use the --with-Tcldom configure switch.  How do I
get a successful build in tcldom/src-libxml2?

As an alternative, I tried building TclDOMPro (in tcldom/src).  That
doesn't work either, because it requires expat, yet doesn't look for
it correctly.  The source files in tcldom/src are trying to #include
<xmlparse.h>, which is a header file in the tclxml distribution of
expat.  That's fine, because that's the version I just built and want
to use.  However, tcldom/src/configure looks for an expat library
matching a pattern like "libexpat*", which is the library built by the
stand-alone distribution of expat.  The library built by the tclxml
distribution is called libTclexpat2.6, so it is not found.  Other than
the file name, are these libraries compatible?  Wouldn't it make sense
to have the tcldompro configure script and source files recognize the
same distribution of expat?
