I had problems with Yann> that and plan to send a bug report for this. There are occasional good uses for -rpath. Once fer-instance: Multiple package sets use the same, but different and incompatible versions of a library. Package set one can put it's library in /usr/lib/package_set_1 and compile all the binaries with `-rpath /usr/lib/package_set_1'. Package set does the sane using /usr/lib/package_set_2. Now we can have two conflicting versions of a library installed at once. In most cases this situation doesn't arise because conflicting version of the same library have different .so names, but fer-instance gtk is in the above state. No upstream .so names, and a need for two conflicting versions to be installed. So outlawing the use of rpath goes just a little bit far. Dissuading it's use would probably be a good thing, but IMO it isn't worth the electrons to store it in the policy manual. It isn't used very often, and I'm pretty sure that when it is used the person(s) using it know what they are doing. (Though X11 used it in imake files for a while. This was changed wasn't it?) Jim (talkative today) PS: If the above description makes sense to me it sounds like rpath lib directories are looked at before LD_LIBRARY_PATH. If this is true it sounds like a bug in the dynamic linker to me and not libtools. I don't know that this is the case because I haven't looked at libtool and how it sets up wrapper scripts. -- @James LewisMoss <[EMAIL PROTECTED]> | Blessed Be! @ http://www.dimensional.com/~dres | Linux is cool! @"Argue for your limitations and sure enough, they're yours."
