OK now though the image is not able to open. It doenst save the image as expected? Is there something else missing that is stopping this?

Network / downloading image for sfml resource use
« on: November 12, 2013, 05:19:17 am »
I havent dabbed at all yet into network of sfml yet. My overall goal was to make a function in which could download an image for me so that i could use it as a sprite. I skimmed the network docs but i dont see such related exactly to it. I pieced together code from what i found on these forums. However the object http was not mentioned in the thread as to what is was. So i guessed as if it was sf::Http. However when doing that though i get errors. I am not sure what exactly is wrong? What am i missing?
the thread i am talking about is:

General / window has no member draw error
« on: November 11, 2013, 08:08:51 am »
I was going through a video tutorial, and the person first shows drawing an image to the screen. However the put window.draw(image_obj) to draw to their screen...when i do the same i get an error for sf::Window has no member draw? My intentions was that is what is suppose to draw the image to screen as shown on the tutorial. The video is using sfml 2.0 and i am using 2.1.
and i get the error:

General / odd error when compiling sfml
« on: November 08, 2013, 04:06:47 am »
history:
It was not 3 hours ago i was going through a tutorial on sfml and compiling it fine, then got an error saying directory was not there. Throughout the process, i had trouble with g++, so i purged g++ from my ubuntu and reinstalled.
I also reinstalled some pre-reqs, but i still get the same error:
after reinstalling i now get this error:
after putting in that argument i get this error:
I am not really sure where to go after this. I have spent the better part of tonight messing with the error i had with g++, and now that i have that working well, i seem to be stuck yet again at sfml. I am not really sure what intially sparked the problem in the first place as i was just compiling sfml between tutorials at the time, not installing, not hcanging config files, or not updating or anything. So its odd that it just seemed to happen out of thin air.
g++ -std=c++11 -Wall -o "%e" "%f" -lsfml-audio -lsfml-graphics -lsfml-window -lsfml-system &&"./%e"
sfml 2.1 on ubuntu 13.04
gcc version 4.7.3
EDIT:
i initially had g++ 4.8 earleir today, and that was working fine. But now i keep getting problems when i switch to it, thus me now having 4.7.3. I am not sure if the version differences are something or not?

so whats wrong with this code? it does the same?
i was initially asking though that the front of the "image" always maintain 'W'
so if the user held S the ship goes down, the ship turns downwards, and if the user held D the ship turned right and moved right? all the times i tried the ship moves in the direction that i wanted but doesnt stop turning?

of course i know what i am talking about...i am talking about myself not understanding the tutorials of this SFML site. besides that is the purpose of forums, is to get numerous explanations from different people (becuz people learn different ways)
Numerous C++ books explain in different ways...it took me at least 5 books just to learn console programming, but there seems to be only one tutorial for SFML. Different people word things that is understanding to some, but confusing to others. This tutorial just seems confusing the way its written.
