/**
 * Build Instructions (Linux)
 *
 * To build this C++ server, first compile the open62541 library. Then, compile the network layer and logging with a C compiler.
 * - gcc -std=c99 -c networklayer_tcp.c -I../include -I../build/src_generated
 * - gcc -std=c99 -c logger_stdout.c -I../include -I../build/src_generated
 * Lastly, compile and link the C++ server with
 * - g++ server.cpp networklayer_tcp.o logger_stdout.o ../build/libopen62541.a -I../include -I../build/src_generated -o server
