System : Debian 9.1 Stretch
Architecture : amd64
SFML version : 2.4
Hello i try to compile this ->
main.cpp
#include <SFML/Graphics.hpp>
int main()
{
sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
sf::CircleShape shape(100.f);
shape.setFillColor(sf::Color::Green);
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
window.close();
}
window.clear();
window.draw(shape);
window.display();
}
return 0;
}
> g++ -c main.cpp
> g++ main.o -o test -lsfml-graphics -lsfml-window -lsfml-system
main.o: In function `main':
main.cpp:(.text+0xc8): undefined reference to `sf::CircleShape::CircleShape(float, unsigned int)'
collect2: error: ld returned 1 exit status
I've tried with cmake too
cmake_minimum_required(VERSION 2.6)
project(apathfindingsfml)
add_executable(apathfindingsfml main.cpp)
# Detect and add SFML
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_modules" ${CMAKE_MODULE_PATH})
set(CMAKE_MODULE_PATH "/usr/share/SFML/cmake/Modules")
#Find any version 2.X of SFML
#See the FindSFML.cmake file for additional details and instructions
find_package(SFML 2 COMPONENTS audio network graphics window system REQUIRED)
if(SFML_FOUND)
include_directories(${SFML_INCLUDE_DIR})
target_link_libraries(apathfindingsfml ${SFML_LIBRARIES})
endif()
install(TARGETS apathfindingsfml RUNTIME DESTINATION bin)
> cmake .

I find this weird that cmake find SFML 2.1.0, since i have 2.4 installed in my computer

Whatever, i tried to compile and then :
> make
[ 33%] Linking CXX executable apathfindingsfml

So i change the argument "2" in find_package to "2.4" :
> cmake .

I've also try to see if the linking is correct, and it seem :

Can you help me please to figure out the problem ?
