Loading dynamic code into C++?

[BCC]

Hi,

Is there any way in c++ to load and execute code from a file,
integrating it into the original application?

I suppose this might be like dynamic classes, except that I would want
to be able to load in flow control statements, commands, variables, etc.

Thanks,
B

No, not portably. However, if you are asking, you must have heard of it,
so there is probably a way on your platform. You need to ask in
a newsgroup for your OS or compiler.

Are you talking about *interpreters*? Then there are those on the market.
Just google for them.

Hmm, possibly, if such an interpreter could be bundled into an existing
application. The goal would be for my app to interpret (so interpreter
sounds good) c++ code from a flat file and execute it.

Maybe there are some interpreters that can be loaded via static libs or
dlls? Ill take a look, thanks for the tip.

Lame. Sorry about the multi reply...

Are you asking about something like Windows dlls?

I know this suggestion doesn't quite meet your stated requirements, but
Python can be embedded in a C++ program. Of course then you would be
interpreting Python rather than C++ but they are at least superficially
similar and Python was made to be interpreted.

There is a C/C++ interperter Ch, it is embeddable. You can load C/C++
code/scripts dynamically.

You can check it at:

You need to make a dynamically loaded library (dl). Here is the link you
can browse in order to do the following :
