Meld problem

[niraj pandey]

Hi ,

I am trying to use meld latest version on RHEL 6 machine. But I am getting
the following error while using it.

./meld-3.16.2/bin/meld
Traceback (most recent call last):
File "./meld-3.16.2/bin/meld", line 259, in <module>
check_requirements()
File "./meld-3.16.2/bin/meld", line 161, in check_requirements
gi.require_version("Gtk", "3.0")
File "/python/v2.7.10/lib/python2.7/site-packages/gi/__init__.py", line 73,
in require_version
raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace Gtk not available

Can someone please help me how to fix this issues. I am using Gtk+-3.16.7
for this.

Thanks in advance.

Niraj

Hi!

Meld uses gtk and gtksourceview from python via gobject interface.
For this to work several things a required. Unfortunately I can't name exact packages for RHEL, so here is an approximated list
1) python-gobject support. You already have this, since you have "/python/v2.7.10/lib/python2.7/site-packages/gi/__init__.py" file
2) Gtk+3 & gtksource libraries >= 3.14. To verify their presence ensure that you can run gedit and check its version is >= 3.14
3) gobject introspection repository ("gir" or "typelib") for Gtk+3 & gtksource. It seems that you lack this.
It it is stored in files like "Gtk-3.0.typelib" and "GtkSource-3.0.typelib" in folder like girepository-1.0/ somewhere in the /usr
If you doesn't have these files anywhere in the /usr it looks like installing some package containing them would help.

Hi !
(Replying off-list now, due to supposing some communication problems)
Didn't you receive this reply several days ago https://mail.gnome.org/archives/meld-list/2016-August/msg00028.html - ?
If no - there can be some communication problem.
If yes - have you any progress in diagnosing if you have problem2 (bad install of gtk+) or problem3 (absence of typelibs), see the email in link above.

Hi.
It looks like now you have an exception earlier then before - the gobject-introspection subsystem doesn't work at all.
And it fails in a bit strange way: module exists but lacks it important method.
According to https://bbs.archlinux.org/viewtopic.php?id=203480 it may be related to bad install of gobject introspection, and "import gi" imports "gi.py" from some wrong location.

Did you install python and gtk in same prefix? It's a bit strange that in previous email you mention /python/v2.7.10/lib/python2.7/site-packages/gi/__init__.py and now you are talking about /tmp/gtk/tools/gtk/lib

Some months ago there was a discussion that leads to successful installation of meld in non-standard prefix, and the key aspects of success was using the same prefix for all components
http://stackoverflow.com/questions/35784566/meld-glib-gio-error-no-gsettings-schemas-are-installed-on-the-system
You may try to install all components in the same prefix and set environment variables mentioned there.

Also in the case of exceptions related to GtkSourceView theme - setting XDG_DATA_DIRS environment variable
https://mail.gnome.org/archives/meld-list/2016-June/msg00018.html
(you don't need this until meld window at least start appearing, it is the last stage).

P.S.
If you didn't received any messages that are directed both to you and to meld-***@gnome.org (like the on I linked in previous mail) there is a definitely email communication problem somewhere,
because meld-***@gnome.org did received the messages like the one I linked below. Please, check you spam folder to ensure that gmail doesn't somwhow learn that meld-***@gnome.org is a "bad" address.

So by now I'm sending this message separately to you and to meld-list to overcome this problem.

Hi Vasily ,
I looked at the link shared by you.
https://mail.gnome.org/archives/meld-list/2016-August/msg00028.html
After reconfigured all the required dependencies I am still not able to run meld (3.16.2). Seems getting some different error.

Forwarding my message to meld-list, since it continues the discussion about another non-standard-prefix meld install.
This message contains investigation&resolution for the exception

gi.require_version("Gtk", "3.0")
AttributeError: 'module' object has no attribute 'require_version'

It was name conflict of pygobject with unrelated gi package (pypi.python.org/pypi/gi/1.2)
(typical sending to both list and Niraj Pandey fails for some reason, in such case only list receives my mail).

Hi.
About GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed - it is typical problem in custom prefix installs.
Additionaly to setting GSETTINGS_SCHEMA_DIR you should install schema file named org.gnome.desktop.interface.gschema.xml from some package like "gsettings-desktop-schemas"
(like in https://mail.gnome.org/archives/meld-list/2016-June/msg00011.html)
About Gtk-CRITICAL **: gtk_icon_theme_get_for_screen: assertion 'GDK_IS_SCREEN (screen)' failed - I didn't hear about this before.
What is your DISPLAY variable? Are you using some remote desktop solution like vnc or ssh -XY?
Is gedit installed in the same prefix working fine? Checking the gedit would help to distinguish python&meld-related issues from gtk&gtksourceview issues.

setenv GSETTINGS_SCHEMA_DIR /tmp/gtk/tools/gtk/share/glib-2.0/schemas/
** (meld:12486): WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files
GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications.

Thanks Vasily ,
I had reconfigured the gi and pygobject and that error went away but now hit another error :(
/tmp/gtk/meld-3.14.0/bin/meld

Any clue for this ?
Once again thanks for taking care of this .

It looks like name confilict issue. The gi-1.2-py2.7.egg doesn't look like python-gobject installation, it more looks like installation of some gist related package https://pypi.python.org/pypi/gi/1.2
This is NOT python-gobject bindings required to run meld.
So ensure that python-gobject is installed (something like python2.7/*-packages/gi/repository/__init__.py must exist)
and remove gi-1.2-py2.7.egg module from this prefix to resolve name conflict (gi-*.egg must NOT exist)
Note that I'm not sure if pygobject version >=3.14 can be installed via pypi/pip. It may be build from source or maybe (I'm not sure) extracted from some prebuilt package like http://koji.fedoraproject.org/koji/rpminfo?fileStart=50&rpmID=5619794
