c source file generated by configure to check for ldap_initialize

Samba version 4.0.7
Aix 6.1
Compiler: IBM xlc

Last lines of "./configure" output:
Checking for ldap_init : not found 
Checking for ldap_init_fd : not found 
Checking for ldap_initialize : not found 
Checking for ldap_set_rebind_proc : not found 
Checking for ldap_add_result_entry : ok 
Checking whether ldap_set_rebind_proc takes 3 arguments : ok 
Active Directory support not available: LDAP support ist not available.
<path>/wscript:760: error: Active Directory support not found. 
Use --without-ads for building without Active Directory support.


Cause:
the generated "test.c" file used in configure checks doesn't have the following required ldap include:
#include <ldap.h>

The compilation gives the following error
"test.c", line 826.39: 1506-045 (S) Undeclared identifier ldap_initialize.

After having extracted the test.c file , added the missing include, it compiles just fine

Hi Gilles,

I'm currently in vacation but will be back at work on Monday August 5, 2013.
I'm running Samba on AIX (5.3, 6.1 and 7.1) and compile it with XL C/C++.
What is your compilation procedure which produce the following errors? (env. variable, configure options, etc.)
What do you have on your system? IBM Tivoli Directory Server/Client? OpenLDAP? Something else?

Best regards,

Yannick Bergeron

I'm created a separate samba projet tree using it's own dedicated
openldap (2.4.26) source tree.
All samba dependencies (like openssl, openldap) are all installed
under a dedicated common prefix.

You should be able to easily reproduce the bug.
(Maybe it's not present when using another version of openldap)

When waf version of "configure" tries to check for the availability of
"ldap_set_rebind_proc" API it uses the attached .c file

With my setup, a compile and link done with the following command
fails when the includes (ldap.h and lber.h) are commented out:

PREFIX=<install_directory_path_here> # openldap and openssl installed
there, also "--prefix" of samba install
> xlc -I$PREFIX/include/ -L$PREFIX/lib -lldap -llber -lcrypto -lssl -o a.out test.c
"test.c", line 829.39: 1506-045 (S) Undeclared identifier ldap_set_rebind_proc.

The *same* commands runs without error after having un-commented  the
two includes lines (ldap.h and lper.h) inside test.c

test.c
Comment 4 Peter 2014-02-11 17:34:04 UTC
I have the same problem with
AIX 7.1
Samba version 4.1.4
openldap 2.4.39

what is the correct procedure here? should I open a new bug?

i don't have a aix box for testing any more. we also don't have any aix box in the build farm. to get aix build work again we a aix machine in the buildfarm and a possibility for us to log in would be very helpful. finally we would also have space for a donated box in the server room here if remote login is more problematic :-)

/usr/src/samba-4.3.5/source3/wscript:700: error: LDAP support not found. Try
installing libldap2-dev or openldap-devel. Otherwise, use --without-ldap to
build without LDAP support. LDAP support is required for the LDAP passdb
backend, LDAP idmap backends and ADS. ADS support improves communication with
Active Directory domain controllers.

Configure can't find ldap_init, ldap_init_fd, ldap_initialize and 
ldap_set_rebind_proc but is able to find ldap.h, lber.h, etc. 
bin/config.log reveals that when it tries to compile their test, ld can't find
any of lber's symbols. Adding lber as a library in CHECK_FUNCS_IN fixes the
problem (see patch). I don't see why lber is required here, could this be my
openldap that's not properly built?

The patch might also resolve Bug 7467.
