[openamq-dev] client application link problem

[blog]

OK, I have mode some progress here:

I worked through the dependencies one by one. adding each library to the
link line when the symbol was first requested.  I end up with this link
line:

g++ -O0 -g3 -o amq_test amq_test.o -L/home/jack/open_source/OpenAMQ/lib/
-lamq_wireapi -lamq_common -lsmt -licl -lipr -lapr -lasl -laprutil
-lpcre -lpthread


The application runs.

My next issue is a troubling compile time warning:
