There's a few other details, but this is the Main Point, yes. > But -u openib_driver_init will work as well, won't it? I'm not entirely sure -- it might (I didn't try it). It *should* force creation of a valid code path into mthca.a and therefore use it for all the resolution that is required (i.e., link in all the parts of mthca.a that are actually required). What I'm not sure about is whether the symbols that mthca needs from libibverbs will be linked in properly (since the linker order is left to right "-libverbs <path>/mthca.a"). I *think* they'll be available from when mthca.a was originally created (i.e., libibverbs.a was statically linked into mthca.a), but I don't know if the linker will be smart enough to realize that there are two copies of some symbols in libibverbs and further to realize that they are actually duplicates of the same underlying symbol, and one can be safely eliminated. It's worth trying (but I don't really care too much :-) ). Every time I think I understand linkers, we get weirdo cases like this that make me remember I have no clue how they work. :-) -- Jeff Squyres Server Virtualization Business Unit Cisco Systems _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
