libusb-1.0 python wrapper

[anett_as@…]

"port lint --nitpick py27-libusb1" gave me the error, that 'openmaintainer' is not allowed... However, I don't think that I can maintain this port. I just want to share the Portfiles I've written and that worked for me.

Notes:

• openmaintainer still requires a maintainer, hence the error. You want nomaintainer.
• Use the Github portgroup to simplify the portfile.
• The stub port should not have any dependencies. Add an if {${name} ne ${subport}} block for them.
• The python portgroup already sets the category. So instead of overriding categories, use categories-append devel
• Delete the revision line because 0 is the default.

Thanks for the comments.

I tried to address all of them to improve the portfile.

Thanks. I just noticed that the only dependency, libusb, has a devel port (libusb-devel). It would be preferable to allow either of them to satisfy the dependency by using a ​file dependency instead of a port dependency.

[anett_as@…]

I converted the port dependency to a file (lib) dependency.

[mf2k (Frank Schima)]

It looks like this port supports python 3.4 and 3.5. Please add those if it does. Then it looks ready to commit!

[anett_as@…]

You are right. When trying to install the port for python 3.5, I realized that there is another dependency (py-setuptools). I added this.

Maybe one can omit the python.default_version line now?

I get a checksum error when I try to build it:

I never got this error. However, when I delete .../macports/distfiles/py-libusb1 folder, I can reproduce the problem. Maybe it is due to the change to the github portgroup. Nevertheless I corrected the checksums... Hopefully it works now.

OK it builds for me now. But I was poking around after it built and I have some more comments:

• Can the examples directory be installed?
• The ​readme mentions dependencies on cpython and pypy. Do those need to be added?
