As you suggested, I commented out everything in resetdb.cpp except for the
connection object and tried to compile. Here are the results:
[dsmith@saquri01 examples]$ make
source='resetdb.cpp' object='resetdb.o' libtool=no \
depfile='.deps/resetdb.Po' tmpdepfile='.deps/resetdb.TPo' \
depmode=gcc3 /bin/sh ../depcomp \
g++ -DHAVE_CONFIG_H -I. -I. -I.. -I../lib -I/usr/local/mysql/include/mysql
-g -O2 -c -o resetdb.o `test -f 'resetdb.cpp' || echo './'`resetdb.cpp
/bin/sh ../libtool --mode=link g++ -g -O2 -L/usr/local/mysql/lib/mysql
-o resetdb resetdb.o util.o ../lib/libmysqlpp.la -lz -lmysqlclient
g++ -g -O2 -o .libs/resetdb resetdb.o util.o -L/usr/local/mysql/lib/mysql
../lib/.libs/libmysqlpp.so
/opt/mysql/4.1.10a-src/lib/mysql/libmysqlclient.so -lcrypt -lnsl -lm -lz

../lib/.libs/libmysqlpp.so: undefined reference to
`std::basic_iostream<char, std::char_traits<char> >::~basic_iostream()'
collect2: ld returned 1 exit status
make: *** [resetdb] Error 1
Then I checked out Warren's first suggestion below. Here is the output of
nm:

Although I'm familiar with using nm, what is this supposed to show? The
man page for nm is not exactly helpful.
I can't say for sure that the Query object is not implicated, as the above
shows the library itself generates link errors.
I would like to get mysql++ working on our SGI. I I would like to avoid
using the MySQL C api if I can.
Thanks for the assistance. Other suggestions are most welcome.

The last system in that class I used was a Cray Y-MP, back before Linux
had even been invented.

Check this GCC mailing list thread out:
http://gcc.gnu.org/ml/libstdc++/2004-09/msg00228.html
That link drops you into the middle of the thread, to a suggestion I'd
like you to try as well.
One other thing: can you hack resetdb.cpp to remove any uses of the
Query object? Basically, I want it to just connect to the database, and
exit. If that links, then this message may be relevant:
http://groups-beta.google.com/group/gnu.g++.help/browse_thread/thread/6b1cc4e3a0b8f1d0
...though not helpful, because nobody replied to it. Well, maybe
helpful: if the Query object is implicated, then this is yet more reason
to change it to not derive from std::stringstream.
