No. On Solaris, this is generally neither necessary nor correct, anyway, because we link our libraries with -zdefs (and you should too!). This means that each shared object already has encoded all of the other objects on which it depends and the runtime loader will load them automatically as needed. When linking against libraries included in Solaris, you should only link against libraries called into from *your* code. It does appear that OpenSolaris SMA libraries are built this way (i.e., correctly), so there should be no need to use the output of something intended to give you additional libraries to link against. You should normally use -z ignore when linking to eliminate unnecessary dependencies. > On my snv57, it gives "-R../lib -L/usr/sfw/lib -lnetsnmp -lgen -lpkcs11 > -lkstat -lelf -lm -ldl -lnsl -lsocket -ladm" Now, I am not sure if > /usr/ccs/bin/ld takes a relative library run path, but libtool certainly ld is fine with this, but the effect is almost certainly not what you want; the search path will depend on the directory from which the executable is eventually run. This is a bug in SMA; I would argue that we should simply not ship this useless script at all, but if we're going to it should output the following, and only the following, when given --libs: -L/usr/sfw/lib -R/usr/sfw/lib -lnetsnmp The other arguments one can give this thing produce similarly broken output as well. The same is true of net-snmp-config-64. I would strongly suggest we simply remove these programs if their stability level permits it. > Is this a libtool bug or somehow things went wrong with netsnmp in /usr/sfw? Both. libtool is defective in so many ways it's impossible and pointless to describe them all; rejecting perfectly valid linker arguments is but one of its lesser offenses. You should never use it for any purpose. And it's also a bug in SMA. Please file one at bugs.opensolaris.org. -- Keith M Wesolowski "Sir, we're surrounded!"
