How to use Lisp in C/C++

Hello everybody,

I would like to incorporate a Lisp program into another, C/C++ based
program. Specifically, I have a set of functions written in Lisp.
These functions, I would like to directly call from C/C++ in which my
main program is written.
So far, I found some hints on the net, but this seems to be either a
very trivial questions or something nobody does. I searched the net,
googled, and read the news groups without finding a satisfying answer.
The most promising tool I found yet has been gcl which generates C
code from Lisp files (gcl -compile -c-file -h-file
<myfunctions.lisp>). Unfortunately, the C code does not make much
sense; it seems the compiler is not designed to allow the code to be
integrated into other projects.

Since mixing program languages is something usual, I was wondering if
anybody knows a tool (rather open source than commercial) or technique
that allows me to do so.

I'll be thankful for every hint, even if this includes the hint that
I'm on a totally wrong track.
Best regards,
Lukas

Hello,

thanks for your hint:

Maybe I'm missing something, but as far as I understood the
documentation of ecls it has pretty much the same functionality as gcl
has regarding the translation to C. Similar to gcl, the generated C
file in not intended to be included into another C/C++ program, but
for generating native object code to load into the Lisp system.
What I am looking for is a compiler to C that allows me to use the
generated C code or object file as part of my own C/C++ program.
Do I miss something here?

Best regards,
Lukas
