shader problems

[deepthought]

how do i get a shader loaded into JOGL and check the status?
here's my current code

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28   29   30   31   32   33   34   35   36   37   38   39   40   41   42   43   44   45   46   47   48   49   50   51   52   53   54   55   56   57   58   59   60   61   62   63   64   65

public void setupshaders(GL gl)    {       String frag = "test.frag";       String vert ="test.vert";           int v = gl.glCreateShader(GL.GL_VERTEX_SHADER);            int f = gl.glCreateShader(GL.GL_FRAGMENT_SHADER);                        shader(gl,v,vert);            shader(gl,f,frag);                    int shaderprogram = gl.glCreateProgram();            gl.glAttachShader(shaderprogram, v);            gl.glAttachShader(shaderprogram, f);            gl.glLinkProgram(shaderprogram);            gl.glValidateProgram(shaderprogram);            System.out.println(gl.glGetString(GL.GL_VERSION));            gl.glUseProgram(shaderprogram);    }                public  void shader(GL gl, int shadernum, String file)     {         String fshadername=file;         BufferedReader shader= new BufferedReader(new InputStreamReader(new BufferedInputStream(getClass().getResourceAsStream(fshadername))));                            String tempstring="";          Vector<String> shaderstringsvector= new Vector();         while(true)         {         try {            tempstring=shader.readLine();         } catch (IOException e) {            // TODO Auto-generated catch block           e.printStackTrace();         }         if(tempstring==null)         {            break;         }         shaderstringsvector.add(tempstring);           }         String shaderstrings[]= new String[shaderstringsvector.size()];         int shaderlengths[]= new int[shaderstringsvector.size()];         for(int x=0;x<shaderstringsvector.size();x++)         {            shaderstrings[x]=shaderstringsvector.get(x);            shaderlengths[x]=shaderstringsvector.get(x).length();         }                       gl.glShaderSource(shadernum, 1, shaderstrings, shaderlengths, 1); gl.glCompileShader(shadernum);     }     }

how do i check the compile status and such? because i keep getting the exception

what's wrong here?

[gouessej]

There is an example of shaders here (JOGL 2):
http://github.com/sgothel/jogl-demos/blob/master/src/demos/hdr/HDR.java

[deepthought]

Ok but should i use JOGL2? aparrently some things are still broken and it hasn't even been released yet. should i wait for a release or just go ahead?

Games published by our own members! Check 'em out!

what the heck i'll just try it.

what the heck i'll just try it.

JOGL 2 is stable enough to do lots of things. I still have some freezes on Windows and Linux Try it and tell us what is wrong.

[deepthought]

if i even try a simple blank window the exception

shows up. what's wrong here?
