How are you doing? I was wondering, could anyone direct to references
on where I can find a lisp to C/C++ translator?
Thanks in advance,

There are a couple of programs called Hobbit and Rabbit that do something
like this, I think. I believe these are specifically for the Scheme dialect
of Lisp. A good place to start hunting might be the SCM home page, at
http://www-swiss.ai.mit.edu/~jaffer/scm.html
There's also a Scheme repository discussed in the FAQ, at CMU, I think.

How do those lambda expressions translate into c?

I don't know how other Lisp-to-C translators work, but I can tell you
how Ilog Talk's compiler does it. For every lambda, we create a named
C function. The first argument to this function is an environment
object, other arguments are regular Lisp objects. Free variable
references in the lambda expression are compiled into references into
the environment object. When a lambda is created in a program, it
creates a function object which has two fields: An environment object
and the code address of the corresponding C function. The environment
object is basically a vector which is created and filled in with the
correct variable cells. When the function is called, the environment
object is passed to the function.
There are some other subleties relating to various optimizations and
special cases like sharing non-constant bindings between functions,
but this is the basic scheme.

Sure con, do a search for 'bigloo.' It's free, and it's pretty
good. In installed it on our HP machines with no problems, which is
more than I can say for a lot of packages.
