Hello, I'm still trying to figure out how to get around preventing output during the ./configure check and I'm still stuck. I can't seem to find anything relevant in the M4 manual, or the autoconf manual. When I use AC_CHECK_DECL, how can I prevent it from outputting to the console for a specific message only? I don't want to supress all messages, only one specific message (and replace it with my own, more complex reusable macro). I've looked at the sources and see it ultimately uses AC_MESSAGE_FD and this is fixed with a value of 6. There's no magic variables it uses to override this with /dev/null. I've seen I can override this macro with my own by just defining a macro of the same name, but I want to only temporarily override it. I see that m4_pushdef, m4_define, m4_defn, m4_popdef may all help, but being new to m4, I'm still trying to figure out what the m4 manuals mean. Alternatively, in 'acgeneral.m4' I see AC_DIVERT_PUSH and wondering if this is appropriate (I don't see any documentation for this in the autoconf manual). In the end, I've done: pushdef([AS_MESSAGE_FD], [/dev/null]) popdef([AS_MESSAGE_FD]) It appears to work. But again, I've not got much experience in this area - can I expect to see problems, or is there another way that is more portable, Thanks for your patience, Jason. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
