Should be possible with recent Autoconf. If you also use Automake, however, you need to get it to not add DESKTOP_DATA_RULE = @DESKTOP_DATA_RULE@ into the Makefile.in. Currently, that is only possible through an undocumented Automake macro, _AM_SUBST_NOTMAKE([DESKTOP_DATA_RULE]). The intention is to fix that for the next Automake release. If you still have problems after this, please show what you tried, and what's output, and the error. Besides the workarounds already mentioned, other possibilities include Automake conditionals. > $(desktop_DATA): $(desktop_in_files:.desktop.in=.desktop) > @list='$<'; for p in $$list; do \ Please note that using $< outside of inference rules requires GNU make. > if test -f "$$p" ; then \ > f=`echo "$$p" | sed > 's/.desktop$$//;$(transform);s/$$/.desktop/'`; \ > if ! test -f "$$f" ; then \ "!
