python-ldap and mac os x tiger, missing symbols

[Bethany J. H. <be...@pi...>]

Hi!  I'm trying to compile python-ldap (2.0.7) on mac os x 10.4.0.  It 
appears to be failing on missing symbols:
ld: Undefined symbols:
_ldap_attributetype_free
_ldap_matchingrule_free
_ldap_objectclass_free
_ldap_str2attributetype
_ldap_str2matchingrule
_ldap_str2objectclass
_ldap_str2syntax
_ldap_syntax_free

The same thing compiles just fine on mac os x 10.3.x.  I'm including 
the same libraries on both compiles.

I heard a rumor that this might be a known issue and easily solved 
through some magic gcc flag.  However, I haven't found anything on the 
net that would tell me what magic gcc flag this would be.  Do you guys 
know anything about this?  Thanks!

Tiger has quite a few issues compiling certain things. For one, I  
have not found a way to compile Python 2.3.5 on it at all. 2.4.1  
works fine. And python-ldap built with Python 2.4.1 works. But  
building for the system-python in /usr/bin fails with problems like  
the ones you saw.

interesting.  i also heard this:

"You need to un-define _XOPEN_SOURCE and _POSIX_C_SOURCE in order to 
successfully compile python sources on Tiger. Also, you need to use a 
build of Python that was configured on Tiger (either our 2.3 port or a 
2.4.1 configured on Tiger)."

I'm trying 2.4.1 out now.  What a bummer.  Thanks!

I did not see these problems after compiling Python 2.4.1 and python- 
ldap HEAD from CVS anymore, there's not much I can say - it worked  
for me.

Well, then it should also work with python-ldap 2.0.7 compiled from
source since at the moment there's no new code in CVS HEAD.

Ciao, Michael.
