cairoDevice.dll error, but it exists..?
4 messages · zubin, Brian Ripley, Duncan Murdoch
Most likely you did not install the dependent DLLs: you need Gtk2 (aka GTk+) installed *and in your path*. That message does not say that 'cairoDevice.dll' cannot be loaded, but a DLL it specified: in interactive use on recent versions of Windows you normally get a pop-up with more information. The CRAN windows/contrib/2.9 ReadMe says Package RGtk2 requires an installed version of Gtk2 with version number >= 2.10.11. and I believe something similar is true of cairoDevice by the same author. A good source of a pre-compiled Gtk2 is http://downloads.sourceforge.net/gladewin32/ , and I guess you need gtk-2.12.9-win32-2.exe from gtk+-win32-runtime. If you insist on using a toolkit designed for Unix on Windows you can expect a rough ride: even when all the Gtk2 components are installed there are lots of issues with fonts.

Don't you get a popup error dialog? I do, and it says that libgdk-win32-2.0-0.dll was not found. Only when I click on okay does it return to the console to tell me about the cairoDevice failure. So I think the real problem is with the libgdk not being present, and that causes the cairoDevice dll to fail to load. Windows doesn't tell R about the reason, it just says it failed. The reason that library was not installed is that I didn't have RGtk2 installed properly. Try library(RGtk2), and make sure it works (and let it install GTK if it wants), and things should be fine.

Duncan, thx - installing GTK fixed the issue :) -zubin
