g++ -std=c++0x -lntcore vision2.cpp -o vision2 'pkg-config --cflags --libs opencv'

It does not work because it cannot file the include.

Also, I cant seem to find any documentation on how to use NetworkTables to send information from the server side. I have looked through the source code but that doesn't help me that much.

You need to add -I<path to ntcore/include directory> to the g++ command line, and the include line should just be #include <ntcore.h> (which will bring in both ntcore_c.h and ntcore_cpp.h).

Even better, if you #include <networktables/NetworkTable.h>, you'll get the same classes/functions you use on the robot program, so e.g. you can call NetworkTable::GetTable() et al. The only difference between this and your robot program is you'll need to run NetworkTables as a client rather than as the server, so first call NetworkTable::SetTeam() and then NetworkTable::SetClientMode() prior to calling NetworkTable::GetTable().
