[clisp-list] trying to make use of make -n

[Hoehle, Joerg-C. <Joe...@t-...>]

Hi,

I have the feeling that CLISP's Makefile does a little too much =
auto/cyclic-magic/detection/regeneration or whatever. This seems to =
cause -n to become useless.

How comes that make -n reports lots of things to be done, when the =
actual make eventually does next to nothing?

build-gcc> make lisp.run             =20
sh config.status --header=3Dunixconf.h =20
config.status: creating unixconf.h   =20
config.status: unixconf.h is unchanged

compare with

build-gcc> make -n lisp.run                                             =
                =20
sh config.status --header=3Dunixconf.h                                  =
                  =20
gcc -I/home/hoehle/include -W -Wswitch -Wcomment -Wpointer-arith =
-Wimplicit -Wreturn-type
  -fomit-frame-pointer -Wno-sign-compare -O2 -fexpensive-optimizations =
-DUNICODE -DDYNAMI
C_FFI -DDYNAMIC_MODULES -x none genclisph.o -o genclisph                =
                =20
(echo '#ifndef _CLISP_H' ; echo '#define _CLISP_H' ; echo ; grep '^#' =
unixconf.h ; echo ;
 grep '^#' intparam.h ; echo ; ./genclisph ; echo ; echo '#endif /* =
_CLISP_H */') > clisp
.h                                                                     =
                 =20
rm -f genclisph                                                         =
                =20
gcc -I/home/hoehle/include -W -Wswitch -Wcomment -Wpointer-arith =
-Wimplicit -Wreturn-type
  -fomit-frame-pointer -Wno-sign-compare -O2 -fexpensive-optimizations =
-DUNICODE -DDYNAMI
C_FFI -DDYNAMIC_MODULES -c modules.c                                    =
                =20
...

[Background: I'm fed up with CLISP regenerating all *.fas/*.mem when =
they are not needed, while I'm playing with modules. Of course, =
Makefile cannot know when it's superfluous, so it plays it safe. How =
can I build a module without having every *.fas/*.mem rebuilt? ]

Thanks,
