I am doing a test installation of GTK+ on top of DirectFB (instead of on X11). (I'm later going to cross compile this for an embedded system.) Now, GTK+ depends on Cairo, and Cairo in turn is compiled with support for either X11 or DirectFB as graphics backend. I'm installing everything to a separate directory (using ./configure --prefix=/home/install_dir), and that is where the DirectFB version of the Cairo libraries end up (in subdir lib/). I'm normally running X11 on this system, so an X11 version of the Cairo library is already installed in /usr/lib64.
libtool is used by make to generate commands for building GTK+. libtool finds both versions of the Cairo library, but unfortunately it places the /usr/lib64 one first, and that makes the linker fail with undefined references. (If I run the command by hand, removing the /usr/lib64/libcairo.so reference, the command works fine, but there are many files to compile/link and I would like a better solution.) This is what is printed by make: /bin/sh ../libtool --mode=link gcc -DG_DISABLE_DEPRECATED -g -O2 -Wall -o gtk-query-immodules-2.0 queryimmodules.o libgtk-directfb-2.0.la ../gdk-pixbuf/libgdk_pixbuf-2.0.la ../gdk/libgdk-directfb-2.0.la gcc -DG_DISABLE_DEPRECATED -g -O2 -Wall -o .libs/gtk-query-immodules-2.0 queryimmodules.o ./.libs/libgtk-directfb-2.0.so -L/home/install_dir/usr/local//lib /home/install_dir/source/gtk+-2.10.13/gdk/.libs/libgdk-directfb-2.0.so -L/home/install_dir/usr/local/lib /home/install_dir/usr/local/lib/libatk-1.0.so ../gdk-pixbuf/.libs/libgdk_pixbuf-2.0.so ../gdk/.libs/libgdk-directfb-2.0.so /home/install_dir/usr/local//lib/libpangocairo-1.0.so /usr/lib64/libcairo.so /usr/lib64/libglitz.so /usr/lib64/libXrender.so /usr/lib64/libX11.so /usr/lib64/libXau.so /usr/lib64/libXdmcp.so /home/install_dir/usr/local//lib/libpangoft2-1.0.so /home/install_dir/usr/local//lib/libpango-1.0.so /home/install_dir/usr/local//lib/libcairo.so /usr/lib64/libfontconfig.so /usr/lib64/libfreetype.so /usr/lib64/libxml2.so /home/install_dir/usr/local//lib/libdirectfb.so /home/install_dir/usr/local//lib/libfusion.so /home/install_dir/usr/local//lib/libdirect.so -lpthread /usr/lib64/libpng12.so -lz /home/install_di r/source/gtk+-2.10.13/gdk-pixbuf/.libs/libgdk_pixbuf-2.0.so /home/install_dir/usr/local//lib/libgmodule-2.0.so -ldl /home/install_dir/usr/local//lib/libgobject-2.0.so /home/install_dir/usr/local//lib/libglib-2.0.so -lm -Wl,--rpath -Wl,/home/install_dir/usr/local/lib -Wl,--rpath -Wl,/home/install_dir/usr/local//lib /home/install_dir/source/gtk+-2.10.13/gdk/.libs/libgdk-directfb-2.0.so: undefined reference to `cairo_directfb_surface_create' collect2: ld returned 1 exit status I have set LD_LIBRARY_PATH=/home/install_dir/lib - is this where libtool gets the path to the correct library? And most importantly, how do I get libtool to place the correct library before the /usr/lib64/libcairo.so one so that the link does not fail?
