running build_ext
# Now actually compile and link everything. self.build_extensions()
# 'self.extensions', as supplied by setup.py, is a list of # Extension instances. See the documentation for Extension (in # distutils.extension) for details. # # For backwards compatibility with Distutils 0.8.2 and earlier, we # also allow the 'extensions' list to be a list of tuples: # (ext_name, build_info) # where build_info is a dictionary containing everything that # Extension instances do except the name, with a few things being # differently named. We convert these 2-tuples to Extension # instances as needed.
