python 3 incompatibility

[mattia-b89]

make works but not pybootchart, there is a python 3 incompatibility i'm on archlinux

[xrmx]

Could you please paste the errors here?

[mattia-b89]

pybootchartgui give me:

Traceback (most recent call last): File "/usr/bin/pybootchartgui", line 20, in from pybootchartgui.main import main ImportError: No module named pybootchartgui.main

[xrmx]

This means that the stuff is installed where your python can't find it. Does 'PY_LIBDIR=/usr/lib/python3.2 make' work?. Obviously change python3.2 to your python version.

If arch is already shipping python3 as default python the arch bootchart2 packager should handle this so please contact him.

[mattia-b89]

no, same error....i've also opened a thread in our forum but nobody has reply

[xrmx]

Could you please try with latest git? If it does not work you can try to pass PY_SITEDIR with the correct directory where your python stores packages which i don't know otherwise please wait the arch bootchart2 maintainer to update the package.

[mattia-b89]

nothing works.....same error

i wait reply on forum because i think is only python related problem not bootchart....

[mattia-b89]

i solved my issue: i must edit PKGBUILD (installation script on archlinux) adding

sed -i -e 's|python2.6|python2.7|' \ -e 's|python\b|python2|g' Makefile make || return 1 make DESTDIR=${pkgdir} install || return 1 sed -i "s|#!/usr/bin/python$|#!/usr/bin/python2|" ${pkgdir}/usr/bin/pybootchartgui

so now it works !

[xrmx]

So your default python is 3.x and you are forcing the script to use python2, which is 2.7.x., instead of python.

What does this gives you? python -c "from distutils import sysconfig; print sysconfig.get_config_var('DESTLIB')"

I cannot see why latest git Makefile should not run out of the box on your platform. Are you sure it gives the very same error after make && make install without your sed expressions?

[mattia-b89]

i get this:

File "<string>", line 1
from distutils import sysconfig; print sysconfig.get_config_var('DESTLIB')
                                                          ^
SyntaxError: invalid syntax

[xrmx]

brown paper bug, fixed in latest git. Now we should start seeing python3 errors :)

[mattia-b89]

yes, compiled latest git without any sed and now obtain:

Traceback (most recent call last):
File "/usr/bin/pybootchartgui", line 20, in <module>
from pybootchartgui.main import main
File "/usr/lib/python3.1/site-packages/pybootchartgui/main.py", line 84
print s
          ^
SyntaxError: invalid syntax

[xrmx]

It would take a few to fix all the issues and actually i don't think i have all pybootchartgui dependencies available on my system so for now you have to ship with your sed rules. Thanks for the time you have spent debugging the issue.

[mattia-b89]

it's a pleasure to help you

so, when you complete to fix this issue, you say me, just write in this thread

hi!

[xrmx]

So i've committed what brings me to a cairo import error to the 'python3' branch. Please checkout that branch and see if it is working fine or not for you.

[mattia-b89]

when i compile, i get this error:

 Sorry: TabError: inconsistent use of tabs and spaces in indentation (draw.py, line   170)Sorry: TabError: inconsistent use of tabs and spaces in indentation (gui.py, line 39)Sorry: TabError: inconsistent use of tabs and spaces in indentation (draw.py, line 170)Sorry: TabError: inconsistent use of tabs and spaces in indentation (gui.py, line 39)

despite that i can install bootchart and if i launch pybootchart, i get:

Traceback (most recent call last):
File "/usr/bin/pybootchartgui", line 20, in <module>
from pybootchartgui.main import main
File "/usr/lib/python3.1/site-packages/pybootchartgui/main.py", line 26, in <module>

[xrmx]

You do not have pycairo for python3 installed.

[mattia-b89]

yes, and it isn't in the our repo, i'll wait it ....

[mattia-b89]

i've installed python-cairo, now i get the same error compiling but when i launch pybootchart i get this:

Traceback (most recent call last):
File "/usr/bin/pybootchartgui", line 20, in <module>

      ^

[xrmx]

It looks you have not installed the python3 branch :)

[mattia-b89]

how i can clone get python3 branch and not the master ?

[mattia-b89]

i append "-b python3" in git clone command and i think i succesful. now i get the same error compiling but when i launch pybootchart, i get:

Traceback (most recent call last):

[xrmx]

Fixed taberror issues in draw.py in python3 branch.

[mattia-b89]

now, when compile:

Sorry: TabError: inconsistent use of tabs and spaces in indentation (gui.py, line 39)Sorry: TabError: inconsistent use of tabs and spaces in indentation (gui.py, line 39)

and launching pybootchart (without bootchart.tgz, i haven't boot using my bootchart entry in grub....):

[xrmx]

pushed some more fixes, please retest.

[mattia-b89]

now without any issues when compile but when i launch pybootchartgui i get (still without a bootchart.tgz .):

[xrmx]

I cannot reproduce your error but i've pushed another fix for the same function, could you please try again and if it does not work send me /var/log/bootchart.tgz file by email? You can find my email address in the git history.
