Eclipse / Makefile / Linux -> Errors ?

[Chi]

Hello all,

i want to run SFML2 in Eclipse under Linux.  I Just start a new Eclipse empty Makefile C++ Project.
All SFML includes and libs are installed in the standardpath.

Makefile

Code: [Select]

LIBS = -lsfml-graphics -lsfml-window -lsfml-system

all: hello

clean:
rm main.o hello

hello: main.o
g++ -g -o hello main.o

main.o:
g++ -c -g main.cpp
main.cpp

Code: [Select]

#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;
}

i klick Build all:

Does anybody know what i do wrong ?

[eXpl0it3r]

If you build in debug mode (gcc -g) then you'll have to link the debug libraries (sfml-xyz-d) and not the release ones (sfml-xyz), as written in the tutorial.

[Laurent]

Your LIBS variable is not used in the makefile.

[Chi]

First, thank you for fast answers.

I delete the debug -g option

Code: [Select]

LIBS = -lsfml-graphics -lsfml-window -lsfml-system

all: hello

clean:
rm main.o hello

hello: main.o
g++ -o hello main.o

main.o:
g++ -c main.cpp

But it is still not working. I dont know what is exactly the problem (alredy bought a book about make but it is not arrived ^^).

Is there still sth. not ok ?

Your LIBS variable is not used in the makefile.

How you meen that ?
Did i must it write different ?

[eXpl0it3r]

You only define LIBS but you don't use it. Add $(LIBS) at the end of the build command (I think).

[Chi]

Thank you ! That works.

The last Problem is just now that the application who is compiled is not starting automaticly in Eclipse when i press "Build & Run"

[eXpl0it3r]

Does exclipse really work with make files? You might want to read up on some Eclipse documentation

I Think that. You can choose by "create project"  a empty makefile project or a autogenerated makefile project ... :x
and if w write only a console application, it works well.
