IDL\ to suit your needs.
If the method you need is already overridden by XWorkplace, go to 3.
SRC\CLASSES and the headers in
INCLUDE\CLASSES accordingly.
INCLUDE and SRC. Modify the SOM code of the
class you need in SRC\CLASSES to call your implementation in your
SRC\YOURDIR directory.
INCLUDE\YOURDIR to the
SOM class code file that you modified. Please think of some useful
function prefix for your exported functions so
that other programmers (including me) can find your code more easily.
Don't forget to update src\classes\makefile so that the class code
file will be made dependent on your new header (which you have added to the
SRC\CLASSES code).
SRC\YOURDIR\, write your own makefile which compiles your
sources. You can take the makefile in SRC\FILESYS\ as a template. This
makefile is pretty smart because it automatically recognizes whether it is called
from the main makefile, and if not, it invokes the main makefile, which in turn
will call the sub-makefiles later. Also, that makefile uses the general makefile
include setup.in in the main directory for compiler setup etc.
Make sure that your makefile writes all .OBJ files into the
BIN directory, which your makefile must create if it doesn't exist yet.
Again, see how the makefile in SRC\FILESYS does this.
Other than that, in SRC\YOURDIR, do whatever you want.
\makefile. This is the "master makefile"
which links all .OBJ modules into the main XWorkplace DLL (XFLDR.DLL).
In that makefile, there is an OBJS macro which lists all the .OBJ files
which are to be linked together.
Add your .OBJ file(s) to the end of that variable (and please, add a comment that you did so).
