I have managed to install the meld 3.14.2 and all the dependency packages, by compiling each package from source and all are installed on a NFS share with --prefix=<base>/meldfor the meld tool && --prefix=<base>/meld/deps for the dependencies.
Finally, I invoked the tool and I can see the GUI. But when I try to do some functionality testing, it throws me errors. I have never used the tool. So, I don't know how it is supposed to work exactly. But users have pointed out the following error, and there can be many other errors too I guess. But the following is one of it.
$meld GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications. II 1 Traceback (most recent call last): File "/applics/platform/meld/meld-3.14.2/lib/python2.7/site-packages/meld/newdifftab.py", line 117, in on_button_compare_clicked tab = self.diff_methods[self.diff_type](compare_paths) File "/applics/platform/meld/meld-3.14.2/lib/python2.7/site-packages/meld/meldwindow.py", line 647, in append_filediff doc = filediff.FileDiff(len(files)) File "/applics/platform/meld/meld-3.14.2/lib/python2.7/site-packages/meld/filediff.py", line 281, in __init__ from meld.gutterrendererchunk import GutterRendererChunkAction File "/applics/platform/meld/meld-3.14.2/lib/python2.7/site-packages/meld/gutterrendererchunk.py", line 33, in <module> class GutterRendererChunkAction(GtkSource.GutterRendererPixbuf): File "/applics/platform/meld/meld-3.14.2/lib/python2.7/site-packages/meld/gutterrendererchunk.py", line 38, in GutterRendererChunkAction MODE_REPLACE: load("meld-change-apply-right"), File "/applics/platform/meld/meld-3.14.2/lib/python2.7/site-packages/meld/gutterrendererchunk.py", line 30, in load return icon_theme.load_icon(icon_name, LINE_HEIGHT, 0) File "/applics/platform/meld/meld-3.14.2/dependencies/lib/python2.7/site-packages/gi/types.py", line 113, in function return info.invoke(*args, **kwargs) gi._glib.GError: Icon 'meld-change-apply-right' not present in theme Please tell me what could be wrong?
The following variables I have used throughout the installation and while using the tool.
PATH, LD_LIBRARY_PATH, PKG_CONFIG_PATH, PYTHONPATH, GSETTINGS_SCHEMA_DIR
The reason for using all these paths is it is completely customized installation, as there were already existing GTK etc versions running on the servers and we don't want to disturb them and want a separate setup for meld, and also in a way that the same installation shared on NFS can be used from multiple servers.
But, unlike the other tools that we usually install, meld has very serious dependencies and we need to compile complex packages like GTK.
Anyhow, can any one tell us what's the wrong with the current installation? And do I need to set more variables and references or do I need to install the modules again with extra options? Now, I have only installed recommended dependencies for each package and left optional package dependencies.
And coming to the error, I can find the png file in my installation <base>/meld/share/icons/hicolor/16x16/actions/meld-change-apply-right.png, then why the tool is unable to find it? What is theme means here?
I was actually quite proud of myself after seeing the window, but now it seems it's just an empty window with zero functionality :(

I had a similar problem running Meld 3.16.0 on Archlinux. In my case the specific error message was GLib.Error: gtk-icon-theme-error-quark: Icon 'meld-change-apply-right' not present in theme gnome (0).
I "fixed" it by creating symbolic links from the directory the Meld icons were installed in to the place Meld is apparently looking for these icons. In my case that that meant ln -s /usr/share/icons/hicolor/16x16/actions/meld* /usr/share/icons/gnome/16x16/actions/.
I consider this a work around rather than a real solution, but at least Meld is working correctly now.
