And You mean the RPATH in the installed executable was wrong ? > that is not trivially overridable at run-time AFAIK so that ld-linux If RUNPATH is available in the binary (exists since a few years, so it should be in your toolchain), then RPATH is ignored. RUNPATH can be overridden using LD_LIBRARY_PATH. It can be enabled with the linker flag --enable-new-dtags I think. If there is RPATH but not RUNPATH, then it can't be overridden. But still if it doesn't find the library in that place, it will continue searching in the other directories, e.g. LD_LIBRARY_PATH. There is also a tool "chrpath", which you can use to change the RPATH entry in an existing executable. It's a bit hard to find, you can get it e.g. from an older revision of kdesvn: http://websvn.kde.org/trunk/kdesupport/chrpath/?pathrev=808076 (it was removed again in revision 808077). It may have issues with endianness.
