I have a macro and in the first lines are:
AC_PREREQ(2.61)
LT_PREREQ([2.2.6])
When I run "autoreconf" I get:
$ autoreconf
configure.ac:33: error: m4_defn: undefined macro: _m4_divert_diversion
configure.ac:33: the top level
autom4te-2.63: /usr/bin/m4 failed with exit status: 1
aclocal-1.10: autom4te failed with exit status: 1
autoreconf-2.63: aclocal failed with exit status: 1
If I remove "LT_PREREQ" then the configure script compiles and I can
move forward.
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.
