Allow the same jsvc binary executable to work with either libcap.so.1 or
libcap.so.2 at runtime

Key: DAEMON-234
URL: https://issues.apache.org/jira/browse/DAEMON-234
Project: Commons Daemon
Issue Type: Improvement
Components: Jsvc
Affects Versions: 1.0.8
Reporter: Phil Clay

I would like to be able to use jsvc on both debian and redhat machines.
Ideally, I'd like to be able to compile jsvc once, and use the same binary on
both platforms.
The problem I am encountering is that the version of libcap varies across
machines.
For example, if I compile jsvc on a RHEL 5.4 machine (which has libcap.so.1),
and then attempt to run the same binary on a Debian 6 machine (which has
libcap.so.2), then the execution fails with:
jsvc: error while loading shared libraries: libcap.so.1: cannot open shared
object file: No such file or directory
In order to create a single jsvc executable that works whether or not
libcap.so.1 or libcap.so.2 is available at runtime, the jsvc code should use
dlopen("libcap.so") and then dlsym all API's instead linking.
