[Dev-C++] Compiling Separately: Separating Code into Modules ...

[JB M. <jb...@so...>]

Hello,

    I am trying to compile a modular program.  Is there an order to this =
(i.e. if I'm using Borland C++ Compiler at the DOS command  prompt I'd =
have to compile each file separately, but with Dev C++ 4 (an IDE) I'm =
not sure.

    When I try to compile the files separately, I get zero errors but =
zero bytes compiled ... what could be wrong?

    I anybody can explain the procedure to me, I would appreciate it.

Below is the main() function "Main.cpp" which refers to the header and =
implementation files.


TIA

Hi J.B.

With Dev-C++, to produce the binary file of an application whose 
source code spans more than one file, create a "Project" and add all
the source files to it. At that point, you just have to build the
project to have the binary produced.

Mark,

   thanks for the tip, but that's not the BIG problem. I am following along
with Jesse Liberty's book SAMS Teach Yourself C++ in 10 Minutes. I
understand the return types, but I was just taking the author's source code
from the web site for the book.

    I am more of a Java Programmer currently, but I used to use Borland C++
3.1 back in the late 80's/early 90's.

    This is specific to the Dev-C++ IDE (which is why I have written to the
list).
    ** I get 0 (zero) errors when attempting to compile the project or its
individual files. **

    I am trying to compile a few files. I have two implementation files with
associated header files, and the main funtion in a separate file. The book
shows the header files with a .h extension and the implementation files with
a .cpp extension.

My questions are these:
    Does the order of files in the project matter?
    Does the extension have to be .hpp (or is .h OK) for         header
files?
    If all of the files are included in the project, shouldn't I just be
able to hit Ctrl-F10 and watch the thing link and     compile     the files,
and then run?

I have not tested it, but it should not matter

Both are fine, my personal choice is ".hpp" for C++ and ".h" for C
as it helps me tell them apart.

I do not remember the exact shortcut, but the answer should be yes.
Also, header files need not be part of the project as far as compiling
is concerned, including them is more a matter of opening those files
quickly.

Sometimes it is better to do a Ctrl-F11 Rebuild all.
