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%\siena.lib wsock32.lib
