cygwin and python-ldap

[Tony G. <dan...@ya...>]

Trying to build pre04 on cygwin using openldap 2.0.21, python 2.2
First problem was not finding lib resolv, though removing it from setup.cfg
doesn't seem to affect anything

Next problem is that I get a lot of ber_printf (and ber_scanf ..) symbols
not found from openldap origins
I ain't no expert, but it seems to be building a shared library, and
complaining about symbols not found in
openldap (which has built OK .. though untested yet)

Any help appreciated

Tony

Please try the setup.cfg mentioned in:

    http://www.geocrawler.com/archives/3/1568/2002/1/0/7452037/

and report back as to whether or not this solves your problem.  I think
you are having a library ordering problem.  I certainly did when I used
the order of the (commented out) libraries in the default setup.cfg.

Thanks,
Jason

Thanks Jason,
Reorder of ldap and lber libs in setup.cfg worked

I've checked in a new setup.cfg with reordered line libs and two
different examples. Please comment.

Please check it out from CVS.

Ciao, Michael.

The new setup.cfg looks good.  Note that the extra libraries for Cygw=
in
are only necessary because Cygwin Python is currently built with a
static _socket module to workaround a fork() problem.  Once my rebase
patch is accepted into Cygwin setup.exe, then I will re-release Cygwi=
n
Python with a shared _socket module (as normal).  At that point, the
Cygwin lines should be removed and Cygwin python-ldap should build wi=
th
the default setup.cfg.

Thanks,
Jason
