    Create multiple executables instead of one

    Hi,

    Lets say I have 10 cpp files, the compiling and linking will normally create one executable. Instead of that I want to create 10 executables - one for each cpp file. Only one of them has a main and the others will be loaded or linked dynamically. How can I do this in C or C++? If not, are there other languages or engines that allow this?

    Not sure if its clear.

    Thanks

    I'm not totally clear on why you would want to do this?

    You say 10 executables? If you want 10 exes, you will need 10 main() functions.

    What you could do is build one executable binary, and 9 DLLs. The binary can then load the DLLs at runtime.

    Hi,

    Ok. I meant one executable and 10 dll's. What if there are 200 such files. What problems would I have if I create one executable and 199 dlls? Memory, speed, complexity etc.

    Thanks.

    You would get performance problems on loading if you didn't rebase them, but other than that, you simply need to define an appropriate interface for them to follow. Hopefully a common interface (preferably C-compatible), such as when these DLLs are all similar plug-in modules.
