Missing icon in Alt-Tab or GNOME 3 launcher/panel on Ubuntu

[typedef]

I compiled latest SVN code of Code::Blocks on Ubuntu 12.04 and installed it with 'make install' but when I press Alt+Tab there's no icon for Code::Blocks in there, nor in application launcher (just an empty square thingy). How do I fix this?

I suggest using dpkg-buildpackage on debian based systems to create packaqges that can be easily (and what's more) clean uninstalled if necessary.

Otherwise, the other stuff has to be done manually (or using the appropriate helperscripts).

Just ran 'dpkg-buildpackage' and installed all generated .deb's - still no icons
