Portable compiler thing?...

You know how some computer programs come with a little command line compiler so that you can make changes to it through little .ini files and then recompile?

How can I do this?

I have just finished the C++ end of my little web plugin system, (yes, another one), and I now need to do the part that automatically compiles a custom DLL.
So, what I need to be able to do is have a program which asks the user a few questions and then does the following:
-Attaches a resource script, with proper changes specified by the user (plugin version number, MIME type, file extensions...), to the dll...
-Changes the value of a variable in the source code...
-And runs some kind of C++ compiler.

These steps can come in any order, of course.

Any ideas?

The alternative to all this would be to expect the user to own a copy of Visual Studio, know how to use it, and be able to view my source code without cackling his poor unsuspecting neck clean off.

Thanks in advance. You will be assisting in the revolutionization of the universe.

What programs do this?

Use GCC instead of visual studio.

Just so you know tho' you probably aren't going to find many hosts that consider allowing the http server access to a compiler of any sorts, a good security measure.
