Re: Is OpenLDAP on OSX?

[Andre John Mas <ajmas@bigfoot.com>]

I just tied the 2.0.11 release an noticed that there were issues with the
configure script. The first problem I get is that it thinks that pthreads
is not available on the platform. A little playing around revealed that
you can compile a program that depend on pthreads without passing any
necessary options. The attached piece of code ( thisfile.c ) compiles as
is. After hacking configure to assume pthreads for Darwin I run
configure again and then I get:

  checking if pthread_create() works... no
  configure: error: pthread_create is not usable, check environment 
settings

Referring back to the example I see that 'pthread_create' is used, so again
another test that fails under Darwin. I am not familiar enough with the
configure files to spend all day hacking them, so I will leave the task
for another day.

Now, if I run configure without threads '--without-threads', configure
completes without any problems and I even manage to do a make depend.
Then when I try compiling I run into a few problems:

I will look into the problem a bit more when I get time. Until then I hope
this can help someone with a bit more time.
