Compile for python 3?

Anonymous created an issue

Hello, I'm trying to get pgmagick 0.5.7 to work with Python 3 on my ArchLinux system.

First thing I had to do was linking to the Python 3 boost libraries, by changing lines 83 and following on setup.py from

if _version >= (3, ):
    boost_lib_target_files.append("boost_python-py%s%s" % (_version[0], _version[1]))
boost_lib_target_files.append("boost_python-mt-py%s%s" % (_version[0], _version[1]))
#gentoo appends the python version numbers to the boost_python libraries
boost_lib_target_files.append("boost_python-%s.%s" % (_version[0], _version[1]))
boost_lib_target_files.append("boost_python-mt")

to

if _version >= (3, ):
    boost_lib_target_files.append("boost_python-py%s%s" % (_version[0], _version[1]))
    # ArchLinux uses boost_python3
    boost_lib_target_files.append("boost_python%s" % (_version[0]))
boost_lib_target_files.append("boost_python-mt-py%s%s" % (_version[0], _version[1]))
#gentoo appends the python version numbers to the boost_python libraries
boost_lib_target_files.append("boost_python-%s.%s" % (_version[0], _version[1]))
boost_lib_target_files.append("boost_python-mt")

Now, when I launch setup.py, I get the following error:

$ sudo python setup.py install
include header path: /usr/include/GraphicsMagick/
Found boost lib: /usr/lib64/libboost_python3

    dists.sort(key=operator.attrgetter('hashcmp'), reverse=True)

I am quite new to building Python packages, so I'm not sure about what is going wrong.

Any help is appreciated.

Thanks,
