Mac OS X problem

pyexiv2 is not officially supported on MacOS X yet (but this is planned).

However Robin Mills did some nice work to generate a Mac universal build recently. I assigned the question to him, he may be able to share his work with you.

@Robin: I haven’t forgotten your contributions and I definitely want to merge them, I have other items on my list right now but I hope to get to it soon enough.

Thanks, Olivier

I'll have a look at that later today. The Mac's in our bedroom and my wife's sleeping in there. My first guess is that he doesn't have doesn't have the python-boost library built!

Thanks for the help Robin, always much appreciated.

@pymind, does this change to the SConscript file fix your problem?

Thank you. Now it works fine. Here is what i had to do to get it work:
$ brew install scons boost boost-jam exiv2
$ cd pyexiv2-0.2.2
$ vi src/SConscript # I just added: env['FRAMEWORKS'] += ['Python']
$ scons BOOSTLIB=boost_python-mt
$ scons install
$ ln -s /Library/Python/2.6/site-packages/libexiv2python.dylib /Library/Python/2.6/site-packages/libexiv2python.so

That's it. Thank you.

Thanks robinmills, that solved my question.

Awesome, thanks for the feedback pymind, that’s precious information!

Hello! I am as well trying to build pyexiv2 for OS X (10.6) without any success so far, although I was very happy to find this post, it still gives me the same (or very similar error) as the one posted here. I've been following the instructions given by pymind, but still no success.
Has anybody an idea what else it could be? Below is the error I get after doing the following:

$ brew install scons boost boost-jam exiv2
$ cd pyexiv2-0.2.2
$ vi src/SConscript # I added: env['FRAMEWORKS'] += ['Python'] below the line env = Environment()
$ scons BOOSTLIB=boost_python-mt

Thank you very much, Frederic

This is the output I get after executing "scons BOOSTLIB=boost_python-mt":

scons: Reading SConscript files ...
scons: done reading SConscript files.

Hi Frederic,
I haven’t tried it myself, but from a very quick glance, it looks like the first warning issued by ld (in /Library/Frameworks//Python.framework/Python, missing required architecture x86_64 in file) is related to the undefined symbols errors you are getting afterwards. It looks like your installation of Python targets the wrong architecture (e.g. x86 on a 64 bits platform).

I'll take a look at this on Tuesday evening (can't do it this evening).

Thanks Olivier and Robin, it was the x86_64 problem. I should have read the error more carefully :) Now it works like a charm...
