Hi Ralf, > What does the last line have to do with the ones before that? Oh, I forgot to mention: I have this stuff in a macro. It's meant to check for certain flags and if accepted by the program, the flag is added to the flag-list. Now I have another macro, which invokes the flag checks by AC_REQUIRE... If someone invokes the macro at another place, with the AC_SUBST in the end, the concatenation happens. > If an initial value of SB_FOOS from the user (./configure SB_FOOS=...) > is to be honored, then maybe you should just check for presence of bar > before adding it? > case " $SB_FOOS " in > *\ bar\ *) ;; > *) SB_FOOS="$SB_FOOS bar";; > esac Never thought of that before! Many thanks, I will check my setups where this applies. Tres cool, I would say! But why is nobody using AS_CASE? > If the user is not involved here, then how come you save and restore > SB_FOOS but not initialize it early in configure? Isn't SB_FOOS empty if not initialised? greetings, Stefan _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
