Description

Setup variables for creation of rpms. It will define several variables useful for creating rpms on a system where rpms are supported. Currently, I requires changes to Makefile.am to function properly (see the example below).

Also note that I do not use any non-UNIX OSs (and for the most part, I only use RedHat), so this is probably generally not useful for other systems.

Required setup:

In configure.in:

   dnl For my rpm.m4 macros
   RPM_RELEASE=1
   AC_SUBST(RPM_RELEASE)

   AM_RPM_INIT
   dnl Enable or disable the rpm making rules in Makefile.am
   AM_CONDITIONAL(MAKE_RPMS, test x$make_rpms = xtrue)

Furthermore, the %GNUconfigure rpm macro has a problem in that it does not define CXXFLAGS for the target system correctly, so for compiling C++ code, add the following line _before_ calling AC_PROG_CXX:

   dnl This is a little hack to make this work with rpm better (see mysql++.spec.in)
   test -z "$CXXFLAGS" && CXXFLAGS="${CFLAGS}"

Changes to Makefile.am (I am trying to get rid of this step; suggestions invited):

   if MAKE_RPMS
   rpm: @RPM_TARGET@

   .PHONY: rpm

   $(RPM_TARGET): $(DISTFILES)
     ${MAKE} dist
     -mkdir -p $(RPM_DIR)/SRPMS
     -mkdir -p `dirname $(RPM_TARGET)`
     $(RPM_PROG) $(RPM_ARGS) $(RPM_TARBALL)
     @echo Congratulations, $(RPM_TARGET) "(and friends)" should now exist.
   else
   endif

Also, it works best with a XXXX.spec.in file like the following (this is way down on the wishlist, but a program to generate the skeleton spec.in much like autoscan would just kick butt!):
