General / SFML & cmake error

« on: May 22, 2018, 09:31:42 pm »

I can run cmake just fine but when I go to make the project I get this error:

CMakeFiles/RogueLike.dir/src/Main.cpp.o: In function `main':
Main.cpp:(.text+0x75): undefined reference to `sf::String::String(char const*, std::locale const&)'  
Main.cpp:(.text+0x93): undefined reference to `sf::VideoMode::VideoMode(unsigned int, unsigned int, unsigned int)'  
Main.cpp:(.text+0xc6): undefined reference to `sf::RenderWindow::RenderWindow(sf::VideoMode, sf::String const&, unsigned int, sf::ContextSettings const&)'  
Main.cpp:(.text+0xf3): undefined reference to `sf::Window::isOpen() const'      
Main.cpp:(.text+0x110): undefined reference to `sf::Window::pollEvent(sf::Event&)'  
Main.cpp:(.text+0x12d): undefined reference to `sf::Window::close()'

Main.cpp:(.text+0x17a): undefined reference to `sf::RenderWindow::~RenderWindow()'  
Main.cpp:(.text+0x1ab): undefined reference to `sf::RenderWindow::~RenderWindow()'

This is my cmake document:

# TODO add non-linux OS compatibility
# Setup
cmake_minimum_required(VERSION 3.0)
project(RogueLike)

set(CMAKE_MODULE_PATH /usr/share/SFML/cmake/Modules)

# Libraries
# set(SFML_STATIC_LIBRARIES TRUE)
find_package(SFML 2 COMPONENTS audio graphics window system)
if(SFML_FOUND)
        include_directories(${SFML_INCLUDE_DIR})
endif()

# Source
set(src
        src/Main.cpp
)

# Generate executable
add_executable(RogueLike ${src})

And finally my code:

#include<SFML/Graphics.hpp>

int main() {
        sf::RenderWindow window(sf::VideoMode(1280, 720), "Hello, world!");

        while(window.isOpen()) {
                sf::Event e;
                while(window.pollEvent(e)) {
                        if(e.type == sf::Event::Closed) {
                                window.close();
                        }
                }
        }
}

Network / UDP packet returns 0 after unpacketing

« on: February 21, 2017, 01:27:09 am »

std::cout << "Sending the player id: " << c.id << std::endl; //prints 1
packet << ugid << pt::handshake << id;
socket.send(packet, sender, rport);
packet >> c.id >> c.id >> id;
std::cout << id << std::endl; //prints 0

I'm handing my client a unique ID which increments every connect. This is for my first client, the id variable is 1 and I pass it to my packet, but when opening the packet the id variable is 0. I'm using sf::UInt32. I'm opening the packet on the server side, but it is 0 on the client side too.

pt::handshake is an enum = 0.

Here are the links to my full server code:
