Hello, I'm trying to build a wrapper for a DepthSense SDK writen Cython but when I run the command python setup.py install this is the output I get:

running install

My setup.py looks like this:

from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext


ext = Extension (
   'depthsense',        # extension name
   ['Depthsense.pyx'],       # cython source
   language = 'c++',     # make a c++ file
   include_dirs = ['/opt/softkinetic/DepthSenseSDK/include'],
   libraries = ['DepthSense'],
   library_dirs = ['/opt/softkinetic/DepthSenseSDK/lib/'],
   extra_link_args=['-Wl,-rpath=/opt/softkinetic/DepthSenseSDK/lib/'],
)

setup (
   name = 'depthsense',
   version = '0.1',
   ext_package = 'depthsense',
   ext_modules = [ext],
   cmdclass = {'build_ext' : build_ext}
)

Thanks in advance.

Looks like you mixed up signed and unsigned data types, possibly already in
your "cdef extern" declarations.

Thanks a lot, the signs were the problem There was one extra uint32_t.
