Probably the easiest way to call C from Tcl is via CriTcl. CriTcl allows you to embed C functions within a Tcl script, compiling and cached the results the first time they are invoked. From then on the compiled C code will be dynamically loaded. You can also use CritBind to pre-build libraries or executables.See CriTcl builds C extensions on-the-fly for more information. stevel

Description: Tool designed to make it easier to integrate functions
written in C/C++ with Tcl 7 and 8/Tk, Perl 4 and 5, Python and Guile.
SWIG is a compiler that takes ANSI C/C++ declarations and builds a
scripting language interface for a number of different languages.
Works for Unix and Win32.
The SWIG documentation and a tutorial are available on SourceForge.
Jswig is an extension by Harco de Hilster which generates
Java native code classes from the SWIG templates.
Should be extracted into SWIG1.1/Examples/java/.
Example of getting SWIG working with Macintosh, by Andy Ptak,
at CMU. There are also SWIG/python patches available by
Robin Dunn. SWIG interface for Eiffel has been made available
by Alex Cozzi, who provides a version for SWIG 1.1p5 as well as one
for SWIG 1.2a1.
The waseda site has a SWIG module for Ruby.
The sourceforge patch reference provides Guile 1.3.4 support.
The digitalsmoo site contains a sample of using SWIG to create
shadow objects for C++ classes wrapped by perl.
Currently version 1.3.9 is available.

Also note RS's clever article "Extending Tcl in C from Tcl".
Still more links are available at [1].
A complementary subject is "How to embed Tcl in C applications".
We need to give guidance to the online Tcl and Tk Tutorials and books [2] that relate to this subject. Among the latter, the books by John Ousterhout and Brent Welch (and co-writers) are probably the ones most frequently recommended for explaining extension-writing.

escargo - Dead link as of 28 Apr 2005. (all links still dead 2 Dec 2007) Not much found by Google of Phillippe or (Philippe) Le Foll since 2000.LV you should be able to find version 1.30 of jWrap at the procplace URL. Is there anything at archive.com?
What: jWrap Where: http://www.fridu.com/Html/jWrap.html http://perso.wanadoo.fr/philippe.lefoll/Html/jWrap-linux-009.tgz http://perso.wanadoo.fr/philippe.lefoll/Html/jWrap-win32-009.zip ftp://ftp.procplace.com/pub/tcl/sorted/packages-8.0/devel/jWrap-1.30-linux86.tgz Description: jWrap parses C/C++ headers or source in order to automatically produce a C/C++ glue stub that can be linked with your component library to produce a loadable Tcl extension. It uses Tcl 8 object representation very heavily. The author claims that the resulting code is faster than similar mechanisms such as SWIG or cTest. jWrap allows jTcl to overload C++ methods or a C++ program to call jTcl methods with no modification to the C++ code. Binary versions for Linux, Win32 and Solaris are available.
