Hi David,
I can't make all my variables static as I have global variables spanning
multiple files. The same applies to some functions.
How can I make the variables and functions link without being visible to the
application as they are not used? I don't want them to appear in any way in
the .lst file.
I have spent most of the day using the strip all option (-s), even with the
keep (-K) option and it seems that I have to keep all the global variables
and functions for it to link properly.
Thanx,
Yvan

To all intents and purposes, you cannot re-create C code from object code.
If you have full, detailed debugging information with the object code then
a
skilled programmer code get some information out. So the easy answer is to
compile your modules without any debugging flags (-g) enabled. If you
additionally make sure that all symbols (functions and data) that are not
exported are declared static (good practice anyway), then these symbols
will
be hidden too.
