I still think this is wrong. Just set the RUNPATH of the first lib correctly (and fix glibc): http://www.sco.com/developers/gabi/latest/ch5.dynamic.html#shobj_dependencies The set of directories specified by a given DT_RUNPATH entry is used to find only the immediate dependencies of the executable or shared object containing the DT_RUNPATH entry. That is, it is used only for those dependencies contained in the DT_NEEDED entries of the dynamic structure containing the DT_RUNPATHentry, itself. One object's DT_RUNPATHentry does not affect the search for any other object's dependencies. _______________________________________________ uClibc mailing list [email protected] http://lists.busybox.net/mailman/listinfo/uclibc
