RE: Alex beep code example threads


Dev c++ will allow you to but if your going to use dev c++ you need to learn
to use your idea there should be a way to add to your include path and to
your lib path in the IDE.  I do not use dev c++ so I don't know how to set
that.

I compile by pressing f9 inside the ide.  Should I be setting the flags you
used, the -l and -o ones? I honestly did not know 
Devc++ would let you compile using it from the cmd line, though
it seems obvious now that you say it.

Have a great day,
Alex
