Thanks for the help.
I'm actually going on minimal knowledge. Mostly all I've done are the cprogramming.com tutorials. Hopefully one of these days I'll be able to get a book

After changing this, would I have to change the << after the string too? That still gives me errors

Thanks again!

Yes, of course. << only makes sense when the left-most element of the line is a stream like cout.

std::string, the C++ string, is not fully compatible with the char* that C uses, and system() was inherited from C.

Do this:

Code:

system( (build command line here).c_str() );

To elaborate: you can't go

Code:

"string" + "string"

but you can use

Code:

std::string("string") + "string"

That gives you a string, so if you need a char* c-string, use

Code:

(std::string("string") + "string").c_str()
