Hmm; I can reproduce this with Autoconf 2.63 but not with current git, with a test case of: LT_PREREQ([2.2.6]) AC_INIT LT_INIT It works in any case when I move LT_PREREQ after AC_INIT, or in a macro definition such as: AC_DEFUN([FOO], [LT_PREREQ([2.2.6])]) AC_INIT FOO LT_INIT Autoconf questions: Is the failure due to a bug in Autoconf 2.63 diversion handling, and if yes, where is it fixed (NEWS and ChangeLog don't seem to indicate)? Question for Jason: you state you had the LT_PREREQ in a macro. Do you expand (call) the macro before AC_INIT? If yes, can you show a small example that reproduces that failure? Asking because I can only reproduce it when LT_PREREQ is actually expanded earlier. Next question, is there a simple way Libtool can work around the 2.63 bug?
