I am using C++ Builder to do some trivial practices. Unfortunately, I have not yet figured out how to compile a .cpp file into a .dll file using on-line command. I am using downlowded C++ Builder, so it is not an IDE. What I need is on-line commands. For instance, to compile several .cpp files into an .exe file, the command reads

bcc32 a.cpp b.cpp c.cpp -exyz.exe

Thank you in advance.
