Runing make I get the following error:

It's fixed.
Thanks for your feebdack.

Thought i would add to this instead of making a new thread, when I use dynamic linkng on linux i get:
error while loading shared libraries: libsfml-graphics-d.so.2: cannot open shared object file: No such file or directory
The only thing I have been able to do to fix it is to delete all the syslink librarie and rename the originals. Is there anything that can be done?
-
The libraries must be in a path the the libraries loader (ld) knows. You must configure it if it's not the case. Use ldconfig for permanent modifications, or the LD_LIBRARY_PATH environment variable for local changes.

I seem to be getting the same error I got a while back again, the window doesnt draw/redraw. This only happens on linux..
This time I ran valgrind to see if I can spot anything this is the log:

Have you tried the SFML examples first?

Appart from the shader exampple which gives a seg fault they all work fine.
just to check this is correctly setup right?

Yes. But this doesn't show the drawing.
You should write a complete and minimal code that reproduces your problem. We'll be able to spot the problem more easily.

Well I think this should work but it gives segmentation fault when building the shader.

Sorry will try to cut it down as much as possible.

I have notced some more problems when it comes to SFML2 and linux,
usiing the following code:
#include <SFML/Graphics.hpp>
#include <iostream>
int main()
{
sf::RenderWindow App(sf::VideoMode(800, 600, 32), "SFML Graphics");
sf::Texture tex;
tex.LoadFromFile("ship.png");
sf::Sprite spr = sf::Sprite(tex);
sf::Shader bloom;
bloom.LoadFromFile("Bloom.fx");
bloom.SetParameter("amount", 0.6f);
bloom.SetParameter("blurSize", 0.5f / 800);
sf::RenderTexture bloomImage;
bloomImage.Create(800,600);
sf::Sprite bloomSprite = sf::Sprite(bloomImage.GetTexture());
while (App.IsOpened())
{
sf::Event Event;
while (App.PollEvent(Event)) if (Event.Type == sf::Event::Closed) App.Close();
App.Clear();
bloomImage.Clear(sf::Color(0.f,0.f,0.f,0.f));
bloomImage.Draw(spr, bloom);
bloom.SetParameter("horizontal", 0);
bloomImage.Display();
App.Draw(bloomSprite, bloom);
bloom.SetParameter("horizontal", 1);
App.Display();
}
return 0;
}
and shader
#version 120
uniform float blurSize;
uniform float amount;
uniform sampler2D texture;
uniform float horizontal;
void main()
{
vec4 sum = vec4(0.0);
float gaussian[17] = float[17] (0.148, 0.145, 0.136, 0.123, 0.107, 0.090, 0.072, 0.055, 0.041, 0.029, 0.020, 0.013, 0.008, 0.005, 0.003, 0.002, 0.001);
int length = gaussian.length();
for (int i = -length + 1; i < length; i++)
{
vec2 coords = vec2(gl_TexCoord[0].x - i * blurSize, gl_TexCoord[0].y);
if (horizontal == 0)
coords = vec2(gl_TexCoord[0].x, gl_TexCoord[0].y - i * blurSize);
sum += texture2D(texture, coords) * gaussian[int(abs(i))] * 0.5;
}
float avg = dot(sum.rgb, vec3(0.299, 0.587, 0.114));
sum = vec4(avg, avg, avg, 1);
vec4 col = (sum * sum * amount) + texture2D(texture, gl_TexCoord[0].xy);
gl_FragColor = col;
}
It exits with error code 1, when i use gdb to debug and set a break point at exit I got this:

Also in linux I have noticed that unless you load textures once the current window has been created they are broken, however in windows you can load textures at any time and the images will be fine. not sure if this is meant to happen or what
