As far as I can tell, runtime linking is not done on AIX without the '-brtl' flag to both the shared objects and the executable. Eventually it is the '-brtllib' flag that actually /enables/ runtime linking for an executable (which is added by the '-brtl' flag and gets disabled with '-bnortllib' when creating shared objects, either explicitly or via '-G' linker flag), but '-brtl' is still necessary to /allow/ a shared object to be subject to runtime linking. But yes, '-brtl' also adds some extra System-V compatibility at linktime, however something like 'DT_SONAME' is still missing. /haubi/ > With AIX style shared libraries, you can put multiple versions of a shared > library, and static versions, > in the same archive file, 32 bit & 64 bit etc. AIX shared libraries are very > flexible, however, > because no other operating system (to my knowledge) supports the same > features, those features are not portable. > > HTH, > > Rob > > On Fri, Jan 21, 2011 at 8:19 AM, Michael Haubenwallner > <michael.haubenwall...@salomon.at <mailto:michael.haubenwall...@salomon.at>> > wrote: > > Hello! > > On AIX, with runtime linking (-brtl linker flag) enabled, the current way > how libtool creates shared libraries prevents any form of "soname" > support, > as there is no way to have the runtime loader to load a different version > of > some shared object (either standalone or as archive member) than the > linker > would record into the next binary when linking against this library. > <snip> _______________________________________________ http://lists.gnu.org/mailman/listinfo/libtool
