Hello all,
I wonder what the proper way is to add an unconventional output (other than
*.o or *.obj) to the Makefile objects. As an example, here's a working way
to add rc resources to a Makefile (output from the resource compiler
rc.exe). It uses the BUILT_SOURCES and adds the output via the LDADD macro.
Working, but not so very pretty.
configure.ac
------------------------------------------
m4_define([prog_version_major], [1])
m4_define([prog_version_minor], [2])
m4_define([prog_version_release], [3])
...
AC_INIT([prog], [prog_full_version], [EMAIL PROTECTED])
# Add support for rc version resource
AC_ARG_ENABLE(use_rc,
AC_HELP_STRING(--enable-use_rc, support rc version resource),
[if test "$enableval" = yes; then
AC_MSG_RESULT([Adding support for rc version resource])
AC_CHECK_PROG(RSC, 'rc.exe -?', rc.exe)
AC_SUBST(RCFLAGS)
AC_DEFINE([PROG_VERSION_MAJOR], [prog_version_major],
[The major version number of this release])
...
fi], enable_use_rc=no)
AM_CONDITIONAL(USE_RC_RESOURCE, [test "x$enable_use_rc" != xno])
------------------------------------------
Makefile.am
------------------------------------------
if USE_RC_RESOURCE
# add resource script to sources
prog_SOURCES += prog.rc
prog_LDADD += prog.res
BUILT_SOURCES = prog.res
CLEANFILES = *.res
endif
# resource compile
.rc.res:
$(RSC) $(RCFLAGS) $(INCLUDES) $(DEFAULT_INCLUDES) -fo $@ $<
------------------------------------------
=> resulting Makefile
------------------------------------------
am__append_1 = prog.rc
am__append_2 = prog.res
am__objects_1 =
am_prog_OBJECTS = $(am__objects_1)
prog_SOURCES = $(am__append_1)
prog_OBJECTS = $(am_prog_OBJECTS)
prog_DEPENDENCIES = $(am__append_2)
prog_LDADD = $(am__append_2)
------------------------------------------
How to automatically get prog.res in $(prog_OBJECTS) instead of
$(prog_LDADD)?
Thanks Erik
