Wireshark · Ethereal-users: [Ethereal-users] small (solved) problem with ethereal-0.8.18's snmp support

[Chris Sylvain <csylvain@xxxxxxxxx>]

I built the ucd-snmp-4.2.1 libraries with SSL (openssl-0.9.6a) support,
and the ethereal configure script would bomb at the second attempt to check
for -lsnmp (this time with -lkstat needed on my Solaris7 host) because it
wasn't also adding -lssl and -lcrypto to the list of libraries.

Here's the output from the unmodified configure:

checking for sprint_objid in -lsnmp... no
checking for sprint_objid in -lsnmp... no
configure: error: SNMP header files found, but sprint_objid not found in SNMP library.

So I modified the second check for -lsnmp and the output looks like this:

checking for sprint_objid in -lsnmp... LIBS = -lsnmp -lsocket -lnsl 
         -lz  -R/usr/local/lib
no
checking for sprint_objid in -lsnmp... LIBS = -lsnmp -lsocket -lnsl  -lkstat -lssl -lcrypto
             -lz  -R/usr/local/lib
yes

As you can see, the modified second check now permits configure to finish
successfully.

Here's the diff for configure (I also changed the datatype for sprint_objid,
not that it matters very much):
