Compiling in .cpp leads to a undefined refernce error

Question

New to working with C++ on Linux and g++.

I am trying to compile a program with library dependencies on using:

g++ -I/home/akhil/cp_libs/OnixS.EurexEtiHandlerCpp-CentOS7-gcc485-c++11-x64-9.5.0/include -I/home/akhil/cp_libs/OnixS.EurexEtiHandlerCpp-CentOS7-gcc485-c++11-x64-9.5.0/include/Trading -o o_c onixs_eurex_session.cpp

It returns

my include dependencies are:

#include <iostream>
#include <sstream>
#include <fstream>
#include <algorithm>
#include <stdexcept>
#include <stdio.h>
#include <stdlib.h>
#include <limits.h>
#include <math.h>
#include <string>
#include <vector>

#include <OnixS/Eurex/Trading.h>

what am i doing wrong here? i know that Trading.h includes multiple other .h files which i thought i was referencing with

#include "OnixS/Eurex/Trading/Export.h"
#include "OnixS/Eurex/Trading/AuditTrail.h"

#include "OnixS/Eurex/Trading/Exception.h"
#include "OnixS/Eurex/Trading/Defines.h"

#include "OnixS/Eurex/Trading/MessageInfo.h"

Please provide [mre]. "Undefined reference" is a linker error, and has nothing to do with your includes, which are parsed by a compiler. EDIT: Looking at your compilation statement, I see nothing related to linking against the library, that you are using. — Algirdas Preidžius, Dec 01 '20 at 12:59
You need to link with the appropriate library as well. It's not enough to just include headers, you need the library too. Use the `-L` option to specify where the libraries are, and the `-l` option to specify the libraries themselves. — john, Dec 01 '20 at 13:01
