Обсуждение: unixware and --with-ldap
Hi all,
When I swithed to the newest version og pgbuildfarm, I noticed that
--with-ldap (now by defaut) didn't work on UnixWare.
This is because, on Unixware, ldap needs lber and resolv.
Not being a configure guru, I made the change bellow locally and that
works for me.
Surely, one of you hackers can come up with a better solution!

The Makefile is far too late --- this has to be adjusted at configure
time, else configure will conclude that libldap isn't available.
(I assume that Unixware's linker is sane enough that the link test
will fail without the supporting libraries.)
I'd be inclined to do something like add
EXTRA_LDAP_LIBS="-llber -lresolv"
in src/template/unixware, and then in configure.in add this where
needed:
if test "$with_ldap" = yes ; then _LIBS="$LIBS" if test "$PORTNAME" != "win32"; then AC_CHECK_LIB(ldap, ldap_bind,
[$EXTRA_LDAP_LIBS],[AC_MSG_ERROR([library 'ldap' is required for LDAP])]) LDAP_LIBS_BE="-lldap $EXTRA_LDAP_LIBS" if
test"$enable_thread_safety" = yes; then # on some platforms ldap_r fails to link without PTHREAD_LIBS
AC_CHECK_LIB(ldap_r,ldap_simple_bind, [$EXTRA_LDAP_LIBS], [AC_MSG_ERROR([library 'ldap_r' is required for
LDAP])], [$PTHREAD_LIBS]) LDAP_LIBS_FE="-lldap_r $EXTRA_LDAP_LIBS" else LDAP_LIBS_FE="-lldap
$EXTRA_LDAP_LIBS" fi else AC_CHECK_LIB(wldap32, ldap_bind, [], [AC_MSG_ERROR([library 'wldap32' is required for
LDAP])]) LDAP_LIBS_FE="-lwldap32" LDAP_LIBS_BE="-lwldap32" fi LIBS="$_LIBS"
fi
I'm not in a position to test that though ...

Hi Tom, Thanks for your help, I will try it ASAP and report maybe tonighgt CET. Also, Makefile.port needs a little patch that I'll send to.

Is libldap a static library on that system?
Or do shared libraries on Unixware generally 'not remember'
the libraries they were linked against (this would be strange).
Or was libldap not linked against liblber and libresolv?
Tom Lane suggested to change configure.in like this:
> AC_CHECK_LIB(ldap_r, ldap_simple_bind, [$EXTRA_LDAP_LIBS],
> [AC_MSG_ERROR([library 'ldap_r' is required for
LDAP])],
> [$PTHREAD_LIBS])
Shouldn't that be
AC_CHECK_LIB(ldap_r, ldap_simple_bind, [], [AC_MSG_ERROR([library 'ldap_r' is required for
LDAP])], [$PTHREAD_LIBS $EXTRA_LDAP_LIBS])
Yours,

Ooops, of course. Like I said, untested ;-)

It could be that whoever compiled libldap there did not include the dependancies at link time. It is legal to build a shared library without resolving all the symbols. libreadline was for a long time in the same position on many linux distributions. The upstream makefile did not specify -lncurses or -ltermcap so every user of readline had to specify that, rather than getting it automatically.

Install autoconf; it's no big deal.

Actually, I did that in the patch-as-committed. It seems to me that
it's probably harmless even if not needed.

I can't find why You mean PTHREAD_FLAGS, right? If it is present in line 1118, it should also be present in line 1133. Can you verify that the part on configure.in between 1065 and 1118, -Kpthread is correctly set on Unixware? If not, thread support for Unixware is probebly broken. If yes, something strange is going on. Yours, Laurenz Albe

This fails because unixware's sigwait has only one arg although (according to doc you can see at http://www.pyrenet.fr:8458) it's thread safe... > If yes, something strange is going on. > indeed > Yours, > Laurenz Albe > Best regards -- Olivier PRENANT Tel: +33-5-61-50-97-00 (Work) 15, Chemin des Monges +33-5-61-50-97-01 (Fax) 31190 AUTERIVE +33-6-07-63-80-64 (GSM) FRANCE Email: ohp@pyrenet.fr ------------------------------------------------------------------------------ Make your life a dream, make your dream a reality.

I can't find why >> >> You mean PTHREAD_FLAGS, right? >> > Nope,I mean PTHREAD_CFLAGS witch is defined in src/templates/unixware PTHREAD_CFLAGS, of course :^) Oops, this seems to be an oversight in (my) original code. I'd say we should change the lines AC_CHECK_LIB(ldap_r, ldap_simple_bind, [], [AC_MSG_ERROR([library 'ldap_r' is required for LDAP])], [$PTHREAD_LIBS$EXTRA_LDAP_LIBS]) to AC_CHECK_LIB(ldap_r, ldap_simple_bind, [], [AC_MSG_ERROR([library 'ldap_r' is required for LDAP])], [$PTHREAD_CFLAGS$PTHREAD_LIBS $EXTRA_LDAP_LIBS]) I know that this is abuse of AC_CHECK_LIB, but it is only a test and LIBS is discarded later.

Clarification, this is the email used to make the patch that was backpatched. --------------------------------------------------------------------------- Albe Laurenz wrote: > >>> I have tried --with-thread-safety and configure fails on ldap check > >>> because for some reason CTHREAD_FLAGS (-Kpthread for UW) is missing > >>> on compile command, although present before that.
