I've got all the library sources compiling successfully, and I ar'd them
into libjgui.a. I then ranlib'd it and copied it to my /djgpp/lib directory.
I then took the main header file, jgui.h, and copied that to my
/djgpp/include directory.

Then, I tried to compile a simple program with it, which used the "Desktop"
class from the library.

The program had
    #include <allegro.h>
    #include <jgui.h>

And was compiled with:
    gxx test.cpp -o test.exe -ljgui -lalleg

This gave me a message that the Desktop class was undeclared.

Now, the desktop class was in a file called jg_desk.cpp, and jg_desk.h.  It
was converted into jg_desk.o through
    gxx -c jg_desk.cpp

And included into the library just like all the other files.  So I'm
wondering why it won't find it.  I also tried with my other files and they
don't work either.

The way I've got them right now, each .cpp file contains a single class
implementation and includes a .h file for its definition.  Now, that header
includes whatever classes the class is derived from / uses and also includes
the main header.

Is this the way it's supposed to be, or am I supposed to include all of the
class headers from the main source code, or... I guess I just don't know.

I guess my question is how do I lay out the classes so that they will all be
correctly implemented in the library?  Do I turn them into .o files like I
have been and just ar them into a library, or do I have the main header
include them all, or do I do something else?

Thanks!
