hi all,
I'm trying to maintain a project that intensively uses a preprocessor called "gob2" to
produce glib/gtk-compatible C. i kinda like it, and want to keep it, but it's
integration to autoconf has quirks. i hope somebody on the list can give me some hints
how to solve it better.
so, gob2 produces both .h and .c/.cc file from a source .gob. it has an option
--no-touch-headers, that will only update the .h if it actually changes.
currently, i'm using the gob2.m4 that comes with the gob distribution, find it at the
end of this message.
and insert "GOB2_CHECK(2.0.0)" into my configure.ac.
my Makefile.ams contain, for every .gob:
BUILT_SOURCES = foo.cc foo.h
pkginclude_HEADERS = foo.h
foo_la_SOURCES = foo.gob foo.cc foo.h
and additionally:
%.cc %.h %-private.h: %.gob
@GOB2@ --for-cpp --no-private-header --no-touch-headers $<
this is the way suggested by the gob manpage, but i deem it unneccessary redundant. it
is also quirky in other ways, dependencies dont work properly (the gob2 manpage states
that --no-touch-headers will 'confuse' automake).
could there be an easier way, so i just have to add my source .gob (probably the .h if
i want it installed) to the Makefile.am? and the dependencies work like supposed?
any help/hints/finished .m4 scripts are highly appreciated. i hope this is the right
list for this question, if not, please notify me privately, and sorry.
