compile python

nTia89 · 2014-09-19 09:19:06

hi fellows,
I'm not new to Arch but I'm very new with python programming.
I would to compile a program that is written in python (2)
here the homepage link: https://code.google.com/p/nemesys-qos/
for who is curious it's a program that produce a, legally effective, document certifying speed of my internet connection (ADSL, fibre, ...)
by performing a particular kind of speed test using a NAP server

anyway, how can I compile it?

With Python there is normally no need to (byte-)compile anything yourself, you can probably just start the program with "python2 Nemesys.py". Make sure you have python2-m2crypto installed.

nTia89 · 2014-09-19 12:57:49

I have python2-m2crypto installed in my system.
I downloaded the source with

svn checkout http://nemesys-qos.googlecode.com/svn/trunk/ nemesys-qos-read-only

but when I try to run the program I get:

[mattia@arch-desktop nemesys]$ python2 Nemesys.py 
Traceback (most recent call last):
  File "Nemesys.py", line 20, in <module>
    import pythoncom
ImportError: No module named pythoncom

Doesn't look like you can -- the source code leads me to believe that its Windows only.

nTia89 · 2014-09-19 13:12:40

No, it's open source and cross-platform program. I'm sure about that because you can download a "precompiled" package for ubuntu (11.04 and above)
I can't provide you a link because it's only available for registered users.
anyway if I download it, I get a .deb package with inside three files:

control.tar.gz, data.tar.gz and debian-binary

jakobcreutzfeldt · 2014-09-19 13:51:47

You need to install it first.

python setup_lin.py install

Scimmia · 2014-09-19 13:55:14

Extract control.tar.gz and post the resulting text file here.

Everything I'm seeing with google says that pythoncom is part of pywin32. Curious to see where debian gets that.

nTia89 · 2014-09-19 16:54:36

@Scimmia
I uploaded in my dropbox the control.tar.gz archive because it doesn't contain any confidential information. Take it from https://db.tt/wIOarsKO

@jakobcreutzfeldt
if I try to execute that command (I tried four combinations of python/python2 with or without sudo) I get:

Sounds like you're missing some packages it depends on; I just set up a quick virtualenv, and I was able to install the module without issue. Do you have virtualenv installed? Try this:

$ pacman -S python2-virtualenv
$ virtualenv2 testpy
$ cd testpy
$ source bin/activate

This puts you into a virtual python environment, so you can install whatever safely. Nice sandbox feature. Note the shell prompt changes to remind you you're in the virtualenv.

(testpy)$ pip install netifaces
(testpy)$ pip install psutil
(testpy)$ pip install M2Crypto

Then, while you're still in the virtual env, try doing the

(testpy)$ python2 setup_lin.py install

. If that all works, then it suggests you just need to be certain you have all the dependencies in your base python environment (assuming you want to put this code in permanently).

* M2Crypto may require you to have swig installed, if you don't have it already. You can't just use pacman to install these packages to the virtualenv, since it all exists in its own directory, wherever you called the virtualenv2 command. Once you're done, you can just do:

(testpy)$ deactivate
$ cd ..
$ rm -rf testpy

and everything's back to normal.

nTia89 · 2014-10-01 19:39:18

first, thanks @DrMag that teach me a new stuff about python

now, I successfully setup the sandbox, then I downloaded source and finally execute the install without errors
but if I try to execute an installed file I get:

(testpy)[mattia@arch-desktop trunk]$ python2 /tmp/testpy/lib/python2.7/site-packages/nemesys/Nemesys.py
Traceback (most recent call last):
  File "/tmp/testpy/lib/python2.7/site-packages/nemesys/Nemesys.py", line 20, in <module>
    import pythoncom
ImportError: No module named pythoncom

DrMag · 2014-10-01 20:22:21

A little google work tells me pythoncom comes in pywin32... I don't know if that works in linux or not, since pywin32 is bindings for windows extensions. Looking at the Nemsys.py file, it imports a handful of modules that are part of pywin32. So you have a reference somewhere that this code actually will work on a linux machine?

nTia89 · 2014-10-01 20:23:49

they provides packages (precompiled) for :
-Winz
-Mac
-Ubuntu

DrMag · 2014-10-01 20:45:31

Ok, after some digging around, I'm not sure Nemesys is the one you want to execute. Try executing gui.py instead; that brings up a gui window for me.

(I tried this without actually installing it, as it requires wxpython, which is a little tricky to install into a virtualenv without tracking down all the dependencies. Just downloaded the code, cd nemesys-qos-read-only/nemesys, and python2 gui.py)

TheSaint · 2014-10-02 03:44:41

Why don't you try to find out whether you have pythoncom in the python searching path?
What will it say?

find /usr -iname pythoncom

(assuming that you have installed in the python library) or look at this.
Sorry I didn't read deeply the DrMag comments.
Anyways you should read the INSTALL, for directions and starting by calling gui.py. Make sure you have installed wxpython and M2Crypto.

nTia89 · 2014-10-02 08:07:27

@DrMag following your suggestion executing gui.py work, showing me the program window, but anyway I can't use it, or better the program can't start measures because it can't find a needed daemon running....

@TheSaint

find ...

returns no results and INSTALL file has no useful information: it says
a- you need python>=2.6
b- you need openssl
c- you need M2Crypto
but absolutely nothing about executing or installing it!

TheSaint · 2014-10-03 03:06:20

Well, pythoncom is only for win platform. You were starting from the wrong point.
For b) and c) points, you should care by your own, as that is not an AUR package nor a package which gives dependencies declarations.
If you want, you may write to the author for supporting him to give more attention on Linux development.
