setup.py doesn't accept --prefix= option

[Ed Catmur]

capella udev-discover-0.2 # python setup.py build --prefix=/usr
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]

error: option --prefix not recognized

I don't know a huge amount about distutils, but your setup.py looks wrong in its handling of this option.

Also, without specifying --prefix the data files are installed into /usr but the executable continues to refer to /usr/local:

Patch merged into master.

Still being one error: it always replaces with /usr/local on udev-discover.in file even if you set /usr as prefix (setup.py line 40)
I've been trying to solve my self with no success. It would be really nice if you could do the work.

Hm, it works fine for me, using python 2.7.2. How are you invoking setup.py?

[J. Félix Ontañón (fontanon)]

I'm invoking this way:

$ sudo python setup.py install --prefix=/usr

Is anything wrong?

The issue was because your solution fixed the setup.py's build command but didn't work with the install one.
I'm adding a patch setup.py after applying yours.
Now --prefix works for build and install commands.
