Compiled extension not installed #2

Open FabricioS opened 6 years ago

According to fbl1991 in issue #1 :

But, when I have run the installation command. The _im7.so wasn't copied to the python library folder. Thus, I got the error 'OSError: dlopen(/Library/Python/2.7/site-packages/libim7/_im7.so, 6): image not found'. So I copy it manually. Could you tell me why?

On my machine, python3 setup.py install tells

It in fact does not copy the compiled extension file to the install dir.

By now, the setup.py script relies on the numpy.distutils.Configuration and its add_extension method. The documentation also mentions the add_installed_library which, contrary to add_extension and add_library, does install the compiled file.

Before any change, I must think again about whether it is required to use numpy distutils here (and why I did it many years ago...)
