Hi, I was porting a package of mine to GNOME 2 (i18n's sake). I have:
$ readelf -d celestia | grep NEEDED | cut -d : -f 2- | sort -u [libGL.so.1] [libGLU.so.1] [libICE.so.6] [libORBit-2.so.0] [libSM.so.6] [libart_lgpl_2.so.2] [libatk-1.0.so.0] [libbonobo-2.so.0] [libbonobo-activation.so.4] [libbonoboui-2.so.0] [libc.so.6] [libdl.so.2] [libgconf-2.so.4] [libgdk-x11-2.0.so.0] [libgdk_pixbuf-2.0.so.0] [libglib-2.0.so.0] [libglut.so.3] [libgmodule-2.0.so.0] [libgnome-2.so.0] [libgnomecanvas-2.so.0] [libgnomeui-2.so.0] [libgnomevfs-2.so.0] [libgobject-2.0.so.0] [libgthread-2.0.so.0] [libgtk-x11-2.0.so.0] [libgtkgl-2.0.so.1] [libjpeg.so.62] [liblinc.so.1] [libm.so.6] [libpango-1.0.so.0] [libpangoft2-1.0.so.0] [libpangox-1.0.so.0] [libpangoxft-1.0.so.0] [libpng.so.3] [libpthread.so.0] [libstdc++-libc6.2-2.so.3] [libxml2.so.2] [libz.so.1] Of those, the package actually uses: [libGL.so.1] [libGLU.so.1] [libc.so.6] [libgdk_pixbuf-2.0.so.0] [libglib-2.0.so.0] [libglut.so.3] [libgnome-2.so.0] [libgnomeui-2.so.0] [libgtk-x11-2.0.so.0] [libgtkgl-2.0.so.1] [libjpeg.so.62] [libm.so.6] [libpng.so.3] [libstdc++-libc6.2-2.so.3] Please note, the first list is the libraries that get included in the program's headers. The stuff in the first list and not in the second from pkg-config's output. There isn't any fundamental problem with this, except that all the packages that provide the first list get included in my package's dependencies, when in fact all those are indirect dependencies. This translates into higher complexity in terms of package installation order. If library a (liba) depends on library b (libb) internally, a program only needs to link against library a and library b is pulled in by the dynamic linker, iff library a's dependencies include library b, like this: $ cc -shared -o liba.so liba.o -lb $ cc -o myprogram -la there's no need for $ cc -o myprogram -la -lb Other dynamic linkers (not GNU's) need this kind of thing, but we are not talking about other dynamic linkers here. Just for laughs: $ ldd ./celestia | wc -l 51 I have the feeling Chris is going to throw my patch out of the window... TIA, -- Marcelo | "Pour encourjay lays ortras."
