Graphics / Re: Beginner: Pixel coordiates, put a pixel in the image

Ok I red a bit about it. But still, I don't understand, How are you able to manipulate the screen into red color, though you have no "image". Respectively, why do I need a image to manipulate single pisels?

I thought if I use graphics that I don't need to use window anymore, because it is included??

?



Edit: ok..now I got that red window, had to use

 g++ -o w2 w2.o -lsfml-graphics -lsfml-window

So I don't have to use it in the header, but Imust  still  link to it, right

But stil: I don't know how to drop a single pixel in that image.

Hello,

I followed the tutorial and managed to compile that programm for a blank window. But then I tried to compile that code from the rendered window tutorial and I got that error

namal@ubuntu:~/Documents$ g++ -c w2.cpp
namal@ubuntu:~/Documents$ g++ -o w2 w2.o -lsfml-graphics
/usr/bin/ld: w2.o: undefined reference to symbol 'sf::VideoMode::VideoMode(unsigned int, unsigned int, unsigned int)'
/usr/bin/ld: note: 'sf::VideoMode::VideoMode(unsigned int, unsigned int, unsigned int)' is defined in DSO /usr/lib/libsfml-window.so.1.6 so try adding it to the linker command line
/usr/lib/libsfml-window.so.1.6: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

My first question what do I do wrong here and second one: How do I put a single pixel into the screen.

Yes,  that was the error. Now I have no compilition errors. But I get this error when I try to run the programm:

/clock: error while loading shared libraries: libsfml-system.so.1.6: cannot open shared object file: No such file or directory

Hello,

 I tried to install the library on two different destributions (ubuntu and Xbuntu) but it doesn't work. Since I don't know witch version I need (32 or 64) I tried them both. For 34 I get an error

make: *** No rule to make target `install'.  Stop.

For 64 I get

make[1]: Entering directory `/home/namal/Downloads/SFML-1.6/src/SFML'
make[2]: Entering directory `/home/namal/Downloads/SFML-1.6/src/SFML/System'

But when I try the clock example in the tutorial I get another error for g++ -o clock clock.o -lsfml-system :

g++: error: unrecognized option ‘-system’

I have no idea what I am doing wrong. Also: I am new to linux. Pls help me.
