Error not fatal when compiling (Archlinux) about glances HOT 10 CLOSED

Currently on Arch Linux there are only packages for pystatgrab for Python 2.7. Your installation is looking at the 3.2 Python installation because that is where /usr/bin/python points to currently. You need to run configure like this to point to Python2:

./configure PYTHON=/usr/bin/python2

This should allow you to successfully make autoconf use Python 2.7 so that it can see the pystatgrab modules.

Also to note, you will also need to change #!/usr/bin/python to #!/usr/bin/python2 in /usr/local/bin/glances.py since you will want glances to run using Python2.

Similar problem (on Archlinux) but with Python 3.2.2.

Though, glances.py will not work :(

$ glances.py 
  File "/usr/local/bin/glances.py", line 53
    print "Error: Can not init the libstatgrab library.\n"
                                                         ^
SyntaxError: invalid syntax

jpablobr,

You most likely will need to run this with Python2. I've changed the #! line of /usr/local/bin/glances.py from #!/usr/bin/python to #!/usr/bin/python2 and everything is working for me now.

If you used the pystatgrab package from pacman then you most likely only have modules for Python 2.7 and not Python 3.2 so using /usr/bin/python won't work.

@ahamilton55 thanks, though the following is what I'm getting know:

7Traceback (most recent call last):
  File "/usr/local/bin/glances.py", line 486, in <module>
    main()
  File "/usr/local/bin/glances.py", line 449, in main
    init()
  File "/usr/local/bin/glances.py", line 444, in init
    screen = glancesScreen(refresh_time)
  File "/usr/local/bin/glances.py", line 158, in __init__
    curses.noecho() ; curses.cbreak() ; curses.curs_set(0)
_curses.error: cbreak() returned ERR

That's with #!/usr/bin/python2 or #!/usr/bin/python2.7 shebangs.

from glances.

Hmm. Not totally sure. Do you have ncurses installed? I currently have ncurses and python-urwid installed but these aren't explicitly stated dependencies.

from glances.

yes, ncurses-5.9-2 and python-urwid-0.9.9.2-1 :/

Sorry I'm not sure then why it isn't working then. It's currently working fine for me.

My install works with the PKGBUILD of AUR and in fact it change #!/usr/bin/python to #!/usr/bin/python2. But when yaourt build the PKGBUILD the error remains.

The program works fine but I want know why there is an error ...

from glances.

I hinted at what the error was referring to in my first comment. What seems to be happening is that the yaourt build is referencing /usr/bin/python which on Arch is Python 3.2. pystatgrab is only used with python2 in Arch so it's placed in /usr/lib/python2.7/site-packages/ so when it goes to check if pystatgrab is loaded and running it fails. The specific error above is throwing a syntax error because in Python 3 you would write that print statement like the following:

 print("Error: cannot init the libstatgrab library.\n")

So glances properly checks and errors out but since yaourt is using Python 3 to test the package it gets the error when printing out the error.

Also this is not an issue with glances but with the way that yaourt is compiling glances.

Ok thanks, i think i can close the issue so.
