Message-ID: <g3qcmb$79l$1@aioe.org>
Hello ,
I am try to introduce lisp to the company's infrastructure, which is
(National Instruments, Visual Studio) C/C++ on Windows.
In order to do so , I would like to call lisp from C/C++ program.
The only way I know so far is to compile DLL from lisp code.
Is there any possibility to call lisp from C/C++ dynamically. I mean without
DLL recompilation after change in lisp side.
Please advise.
Dmitry

You should have a look at ECLS http://ecls.sourceforge.net/. The
commercial implementations have more ways of doing that. YMMV.

You can use any IPC mechanism your Lisp supports. As long as the
C/C++ visible interface doesn't change, you should be able to use the
new Lisp code immediately.

Maybe I should clarify myself.
Or maybe I am asking something so obvious, that any one should know that.
Please advise me . How can I call lisp from C/C++ program
on Windows, send to it pointer on "something" , change that "something" in
lisp, and "return" back to C/C++ program.
Thanks, Dmitry

You didn't say you wanted to pass pointers and you did ask how to call
the Lisp without "recompiling a DLL" after every change.
One way is to embed Lisp in your C/C++ program - on Windows Corman is
an excellent choice although it's not quite standard compliant. ECL
or ECLS are also good choices.
The other way is to run Lisp in a separate process and use an IPC
mechanism that supports passing pointers, such as COM or Corba. Again
Corman is a good choice - it is implemented as a COM object.

Yes , that exactly what I want - call lisp function without compiling and
recompiling them to .DLL and be able to pass C/C++ pointers as
an arguments to lisp functions.
Till now I am not succeed to connect to Corman's COM interface,
actually I can't even find it.
Thanks, Dmitry

AFAIK, the COM interface isn't documented, but you can find it in the
"include" directory. Also, if you look in the directories
"clconsole", "clconsoleapp" and "CormanLispServer", you'll find
examples of using it.

Thank you George,
It is sound like you actually have an experience with lisp integration
on windows. I will try to do my best, before asking for code snippets.
Thanks again, Dmitry

Have a look at myecl.c

Maybe I should clarify myself.

Please advise me . How can I call lisp from C/C++ program
on Windows, send to it pointer on "something" , change that "something" in
lisp, and "return" back to C/C++ program.
Thanks, Dmitry

The easiest would be to use ECLS, which is an Embeddable Common Lisp System.
