Putting the AC_CANONICAL_xxx macro(s) *after* AC_INIT seems to
work, and
could fix cross-compilation problems, according to Jeff Morriss, and
I should also mention that I only think it should work because of this
commit which is what added the AC_CANONICAL macro there (together with
CC_FOR_BUILD) in the first place:
http://anonsvn.wireshark.org/viewvc?view=rev&revision=19753
Which was a fix for bug 1185:
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=1185
The patch for that bug added an AC_CANONICAL_BUILD call between an
AC_CANONICAL_HOST call and an AC_CANONICAL_TARGET call; the change in
question, however, added a commented-out AC_CANONICAL_BUILD and also
commented out the existing AC_CANONICAL_HOST, and added the comment
from the autoconf documentation:
dnl The user is encouraged to use either `AC_CANONICAL_BUILD', or
dnl `AC_CANONICAL_HOST', or `AC_CANONICAL_TARGET', depending on the
dnl needs. Using `AC_CANONICAL_TARGET' is enough to run the two other
dnl macros.
In revision 19752, the AC_CANONICAL_ calls were after the AC_INIT
call. The "Have autoconf generate "ustar" tar files by default. This
should let us have paths longer than 99 characters." change was the
one that moved them before the AC_INIT call. Gerald? Why was that
move done?
