Generally, these sorts of errors can be avoided by using AC_REQUIRE([AC_CANONICAL_BUILD]) rather than flat-out invoking AC_CANONICAL_BUILD. On the other hand, this ChangeLog may shed some light on the matter: 2005-08-26 Stepan Kasal <[EMAIL PROTECTED]> * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE; but change the m4_divert_text to m4_divert_once. The message is printed by AC_DEFUN_ONCE, but the current git sources of Autoconf don't use that any more as of the above-mentioned change. So my guess is that you are still using autoconf 2.59 instead of 2.61. Try upgrading, and seeing if that makes the message disappear. - -- Don't work too hard, make some time for fun as well!

Only plausible solution is setting LDFLAGS before ./configure or using --with-zlib. BTW, libxml is not the only app where you'll run into this problem. You should also look into LD_RUN_PATH. We build libxml: LDFLAGS="-R[zlib path]/lib" ./configure --with-zlib=[zlib path] -- albert chin ([EMAIL PROTECTED])
Different linkers at different times?
I'm cross-posting this to the autoconf and libtool lists, because I'm not sure whose "jurisdiction" this is. I accidentally found this while trying to compile libxml2-2.4.5 under Solaris. I say "accidentally" because was compiling without /usr/local/lib in my $LD_LIBRARY_PATH, which was probably silly. However, I think this might still be a legitimate concern. The problem is with the AC_CHECK_LIB(z, gzread) call in libxml's configure.in. What happens is that the configure script uses gcc and finds -lz successfully, and everything moves on as if libz is available. However, libtool uses /usr/ccs/bin/ld when attempting to link the library, and is unable to find -lz at that point. I guess this is because gcc always looks in /usr/local/lib by default and the Solaris build tools don't. I can work around this by specifying the exact location of zlib (--with-zlib=/usr/local) or by forcing use of the Solaris C compiler (export CC="/usr/ccs/bin/cc")... but it seems like it's not good that I can get myself into a situation where the configure script will succeed but the build will always fail. I've rebuilt the configure script with autoconf 2.52, and I still see the problem. It looks like libxml was developed with libtool 1.4. Is this worth worrying about, or does this fall into the "well, the silly user [me] should set up $LD_LIBRARY_PATH properly" category? Thanks! KEN -- Kenneth J.
