g++ include directory in the headerfile

Question

The path to my .cpp and .h files: /home/quasiturbine/ServerProject/Network/NetworkIncludes/

There you can find TCP_Connexion.h and TCP_Connexion.cpp

In the .cpp file, I got #include "NetworkIncludes\TCP_Connexion.h" and default constructor/destructor. That's it.

G++ command:

g++ -o program -I/home/quasiturbine/ServerProject/Network/ /home/quasiturbine/ServerProject/Network/NetworkIncludes/TCP_Connexion.cpp

fatal error: /home/quasiturbine/ServerProject/Network/NetworkIncludes/TCP_Connexion.cpp:1:43: fatal error: NetworkIncludes\TCP_Connexion.h: No such file or folder #include "NetworkIncludes\TCP_Connexion.h"

What is wrong and how can I fix it?

I think you want to add you Project Folder as include Directory. With gcc/g++ you Need to add the following flag: `-I/home/quasiturbine/ServerProject/Network/` — Thomas Sparber, Nov 20 '17 at 09:42
try to use `#include ` instead of `#include "NetworkIncludes\TCP_Connexion.h"` — Thomas Sparber, Nov 20 '17 at 09:45
I dont know if I was clear...after program, it's in Include, not a link — Gabriel Proulx, Nov 20 '17 at 09:45
by the way how did you make that capital i? If I do a capital i, it looks like this : I, i = I no bars on top and bottom... maybe it's the issue? — Gabriel Proulx, Nov 20 '17 at 09:48

The problem is, that you are using backslashes \ when you should be using forward slashes /. Backslashes in include paths are undefined behavior before C++11 and implementation defined afterwards (reference).

So change your include to

#include "NetworkIncludes/TCP_Connexion.h"

and you should be good to go.
