I followed all instructions for installing the plugin. When I try to open a section with acroread I get the error meassage "GTK+ UI Toolkit libraries, ver. 2.4 or greater were not found". Problem is, installation of these libraries is a real headache - requires updating pango, glib etc. which can lead to total destruction of your operating system if, like me, you don't know what you are doing. Is there a workaround / can the FileOpen people solve this?

Simon2007, we have asked the FileOpen folks to look into this and will post any new information here. Yours is the first report of this problem. GTK+ is the Linux GIMP toolkit on which the GNOME desktop is based.

Is anybody else seeing this problem?

OK, we've heard from FileOpen. The answer seems to be yes, the FileOpen plug-in does require GTK+. The reason is that it is used in Adobe's "linux.mak" makefile and in all of Adobe's sample plug-ins code on which the FileOpen plug-in is based. The exact references in the makefile are:

GTK_DIR1 = /usr/lib/gtk-2.0/include
GTK_DIR2 = /usr/include/gtk-2.0
GTK_DIR3 = /usr/include/atk-1.0
GTK_DIR4 = /usr/include/pango-1.0
GTK_DIR5 = /usr/include/glib-2.0
GTK_DIR6 = /usr/lib/glib-2.0/include
X11_DIR = /usr/X11R6/include

Simon2007, the fact that your system is requesting a version number greater than 2.4, while the above references only 2.0 might possibly mean that you actually have an inconsistent set of library versions installed. (Yes, I know that doesn't help solve the problem!) I don't think there is anything that we can directly do for you at this point. Does anyone else have any suggestions?
