python-mcrypt install on Mac OSX

[Guest]

Hi,
I'm having a hard time getting python-mcrypt extension to build.
I installed libmcrypt with --prefix=/usr and I checked that the
library exists

-rwxr-xr-x 1 root wheel 352K Sep 19 16:53 /usr/lib/libmcrypt.
4.4.8.dylib*
lrwxr-xr-x 1 root wheel 21B Sep 19 16:53 /usr/lib/libmcrypt.
4.dylib@ -> libmcrypt.4.4.8.dylib
lrwxr-xr-x 1 root wheel 21B Sep 19 16:53 /usr/lib/
libmcrypt.dylib@ -> libmcrypt.4.4.8.dylib
-rwxr-xr-x 1 root wheel 801B Sep 19 16:53 /usr/lib/libmcrypt.la*

But this is the output from setting up python-mcrypt

# python setup.py build
running build

What am I missing here? I linked PHP with the same libmcrypt library
just fine. This is only happening for this extension only.

Would appreciate any help, thx

Try setting the DYLD_LIBRARY_PATH might help. Or altering the setup.py
to add -L/usr/lib.

Nope, that didn't do it.
The first clue I got that something is wrong was that mcrypt.h could
not be found. Even though it exists in /usr/include. So I added the
include_dirs and library_dirs to setup.py


mcrypt=Extension(
"mcrypt",
sources=["mcrypt.c"],
include_dirs=['/usr/include'],
libraries=["mcrypt"],
library_dirs=["/usr/lib"],
define_macros=[("VERSION", '"%s"'%VERSION)]
)

setup(name="python-mcrypt",
version = VERSION,
description = "Python interface to mcrypt library",
author = "Gustavo Niemeyer",
author_email = "(e-mail address removed)",
license = "LGPL",
long_description = \
"""
Python interface to mcrypt library.
""",
ext_modules = [mcrypt],
)


I'm still getting the same output:

It makes no sense, so I went to another brand new mac, installed
XCode and Python 2.5 and libmcrypt-2.5.8. I got the same results. So
I'm at a loss, how can ld not see libmcrypt.

I'm digging into disutils.sysconfig to see what is the build
environment that disutils is using.
Does anyone know how to build an extension manually? without using
distutils. If I can get it to build outside of distutils I might be
able to figure out what need to be done.

Thx

Ok, I got it to work, but it still makes no sense. I had to install
libmcrypt with --prefix=/usr/local.
If I do it with --prefix=/usr then for some reason ld won't find it
when building python-mcrypt.

Obviously I had to also change the include_dirs and library_dirs in
the setup.py file.


I thought I'd share that so hopefully someone can explain what that's
all about.

Thx
