I don't think there's much about it in the manual.
- GPC has an "--automake" option that recursively invokes GPC to
compile all modules. However, it has problems in tricky situations
(involving cyclic dependencies), and does not support a user
controllable linker step.
- The external GP utility (http://fjf.gnu.de/misc/gp.tar.bz2) is
meant to replace automake, and will also call GPC for all modules
and for linking. By default, linking is not user controllable.
However, you can use the options "-c" (don't link) and
"--print-objects", and then do what you need to with the objects.
Also, the source of GP is written in Pascal, so you can modify it
yourself if necessary (procedure Link might be the start to look
at). If you make your changes in generally useful form (i.e.,
options, rather than hardcoding what you need), you can send the
patch here, so I can integrate it (but, of course, you don't have
to -- the GPL also allows making your own private changes).
- Of course, you can also hand-write a Makefile, C style. GP itself,
in order to avoid a chicken-and-egg problem, contains such a
Makefile (requires GNU make). It's probably more generalized than
you need (including support for cross-compiling, support for
Dos/Windows peculiarities, rules to build documentation, etc.), so
you can probably do with something simpler.
