Hello,
i'm reporting here the Debian bug: http://bugs.debian.org/676450 >>>
Currently python-psutil fails to build on Debian GNU/Hurd. (Doesn't recognize 
gnu system).

Attached is a patch for building on Hurd.

Cheers,

Ciao Sandro,
have you also tried to run the test suite?

You're right, I hadn't , but I suppose the fellow debian developer had, even if 
he didn't reported in the bug log. I'll ask him for the output or i'll run them myself.

Well, the patch as-is can't work as it only includes the C posix extension 
module [1].
The remaining part concerning process management is missing.
I don't know anything about GNU/Hurd. Is it a Linux-like OS? Does it support 
/proc filesystem? If so can we use the existing Linux implementation[2]?

GNU/Hurd is a linux-like environment, where the working env is the same (GNU), 
but the kernel is different: instead of using Linux it uses Hurd. It seems 
there's a basic support to /proc but it probably misses all the info psutil uses.

I noticed that too, so I asked the developer that opened the bug to investigate 
further and at least get to run the tests.

I'll update this bug as soon as I have some updated info.

I've started working on a GNU/Hurd port. Should I keep on working on it ? Do 
you mind getting a huge patch ?

Sure go on, although I'm not sure when I'll have time to look into it.

once we have a patch I can try to run the code on a Debian porterbox and see 
how it goes. But I can't commit too much time, but Debian uses would love to 
have a port on GNU/Hurd :)

I pushed my work at https://gitorious.org/python-psutil-hurd .

Currently, out of the 93 tests, I get:
- 50 working
- 5 skipped
- 2 failed
- 36 errors

I'll try and keep improving this port.

Closing out as outdated.

hey @giampaolo this still happens with 5.4.1:

https://buildd.debian.org/status/fetch.php?pkg=python-psutil&arch=hurd-i386&ver=5.4.1-1&stamp=1511665962&raw=0

for python in python2.7 python3.6; do \
	$python setup.py build; \
	$python-dbg setup.py build; \
done

/<<PKGBUILDDIR>>/debian/rules:7: recipe for target 'build-arch' failed

should this issue be re-opened?

Well, yes this is still happening :) and blocking the availability of a hundred packages in Debian.
Hurd's /proc implementation is mostly following Linux' shape, so probably much of the Linux code can be just called as such.

What happens if you fix setup.py and run tests?
