# publisher.cc

This is an example of how to program a simple subscriber application. To compile this example on a GNU/Linux system or on other Unix-like systems, assuming Siena has been installed in $prefix, execute:

      c++ publisher.cc -o publisher -I$prefix/include -L$prefix/lib -lsiena

On some platforms (notably Solaris), you will have to link additional libraris (e.g., -lsocket -lnsl).

To compile this example on a win32 system, using Visual C++, assuming Siena has been installed in %prefix%, execute:

      cl -I%prefix% -GX -c publisher.cc
      link -out:publisher publisher.obj %prefix%.lib wsock32.lib
