Re: Shader doesn't compile with Python 3

Hello,
I came also across this issue, when using pyopengl 3.0.2 with python 3.3.0
, the following code

Shader = compileShader("""#version 330
in vec4 position;
void main()
{
    gl_Position = position;
}""", GL_VERTEX_SHADER)
    fShader = compileShader("""#version 330

out vec4 outputColor;
void main()
{
   outputColor = vec4(1.0f, 1.0f, 1.0f, 1.0f);
}""",  GL_FRAGMENT_SHADER)

generated the following error:


RuntimeError: ('Shader compile failure (0): b\'Vertex shader failed to
compile with the following errors:\\nERROR: 0:1: error(#132) Syntax error:
"b" parse error\\nERROR: error(#273) 1 compilation errors.  No code
generated\\n\\n\'', [b'#version 330\n\nin vec4 position;\nvoid
main()\n{\n    gl_Position = position;\n}'], GL_VERTEX_SHADER)


this was remedied by commenting out line 217 in shaders.py


def compileShader(source, shaderType):
    """Compile shader source of given type

    source -- GLSL source-code for the shader
    shaderType -- GLenum GL_VERTEX_SHADER, GL_FRAGMENT_SHADER, etc,

    returns GLuint compiled shader reference
    raises RuntimeError when a compilation failure occurs
    """
    if isinstance(source, str):
        source = [ source ]
    #source = [ as_bytes(s) for s in source ]           # offending line

    shader = glCreateShader(shaderType)

Hope this is of use,

Stuart
