Summary0000607: Possible bug in FindGTK.cmake
DescriptionI have recently tried compiling vxl/vgui using gtk but without glut on a> Fedora core 1 machine. This has caused a link error because libgdk is> apparently dependent on libXi, but libXi is not included in the> dependencies in FindGTK.cmake. Here's an example error:> c++ -fPIC basic01_display_image.o -o> /home/brendan/vxl-1.0.0/bin/core/vgui/examples/basic01_display_image> -rdynamic -L/home/brendan/vxl-1.0.0/bin/lib> -L/home/brendan/vxl-1.0-beta/gtkglarea-1.2.2/gtkgl/lib -L/usr/X11R6/lib> -lgtkgl -lgtk -lgdk -lgmodule -lglib -lGLU -lGL -lX11 -lXext -lvgui> -lvnl_algo -lnetlib -lvnl -lvil1 -lvil -ljpeg -ltiff -lpng -lzlib -lvgl> -lvpl -lvbl -lvul -lgtkgl -lgtk -lgdk -lgmodule -lglib -lQv -lvcl -lm> -lGLU -lGL -lX11 -lXext -lX11 -lXext> -Wl,-rpath,/home/brendan/vxl-1.0.0/bin/lib:/home/brendan/vxl-1.0-beta/gtkglarea-1.2.2/gtkgl/lib:/usr/X11R6/lib> /usr/lib/gcc-lib/i386-redhat-linux/3.3.2/../../../libgdk.so: undefined> reference to `XGetDeviceMotionEvents'> /usr/lib/gcc-lib/i386-redhat-linux/3.3.2/../../../libgdk.so: undefined> reference to `XFreeDeviceList'> /usr/lib/gcc-lib/i386-redhat-linux/3.3.2/../../../libgdk.so: undefined> reference to `XQueryDeviceState'> /usr/lib/gcc-lib/i386-redhat-linux/3.3.2/../../../libgdk.so: undefined> reference to `XListInputDevices'> /usr/lib/gcc-lib/i386-redhat-linux/3.3.2/../../../libgdk.so: undefined> reference to `XFreeDeviceMotionEvents'> /usr/lib/gcc-lib/i386-redhat-linux/3.3.2/../../../libgdk.so: undefined> reference to `XFreeDeviceState'> /usr/lib/gcc-lib/i386-redhat-linux/3.3.2/../../../libgdk.so: undefined> reference to `XOpenDevice'> /usr/lib/gcc-lib/i386-redhat-linux/3.3.2/../../../libgdk.so: undefined> reference to `XSelectExtensionEvent'> /usr/lib/gcc-lib/i386-redhat-linux/3.3.2/../../../libgdk.so: undefined> reference to `XUngrabDevice'> /usr/lib/gcc-lib/i386-redhat-linux/3.3.2/../../../libgdk.so: undefined> reference to `XGrabDevice'> > I have attached a modified FindGTK.cmake (sourced from> $vxl/config/cmake/Modules/NewCMake/FindGTK.cmake) that solves the link> problem simply by adding libXi to the dependencies. Anyway, not sure if> this is a general problem or just my problem, but I thought I'd let you> know.

 OK, I checked in a version that I think has your change in it, give it a try. Next please use the Create Attachment button in the bug tracker.
Thanks for the fix.
