Loading shader firom file: GL_error 'illigal counting'

[CarstenT]

Hi all,
I'm using a shader that on and off generates an error.

//std::ifstream::pos_type mSize;
int mSize;
std::ifstream ctFile ("F:/Projekter/GLFW3_2/vertShader6.txt", std::ios::in|std::ios::binary|std::ios::ate);
    if (ctFile.is_open())
    {
        printf("ctFile is_open\n");
        mSize = ctFile.tellg();
        printf("ctFile mSize : %i \n", mSize ) ;
        checkErrors() ;
 
        char *buffer = new char [mSize];
        ctFile.seekg (0, std::ios::beg);
        ctFile.read (buffer, mSize);
        ctFile.close();
        buffer[mSize] = '\0';
 
        const GLchar *vertexShaderChars[] = { buffer };
        ....

I detect the error at checkErrors(). It's printed in my local language and translates to something like 'illigal counting'
The error sometimes generates a faul status:
glGetShaderiv(vertShader, GL_COMPILE_STATUS, &status);

I make a printf() of 'buffer' and it provides a correct visual impression of the shader-code/text.

It 'did' bypass GL_COMPILE_STATUS earlier without the error spawning a faul status, and I would have a functioning program ..

It probably takes a newbie to produce the code above ... any suggestion of a more straightforward code is welcome.

hi,
I changed my approach to a very elegant way presented at
http://stackoverflow.com/questions/8...-loading-fails
... and I get the same error.
It would belong to something about 'vec4 coll' ..?

#version 330 core
precision mediump float;
precision mediump int;
layout(location = 0) in vec4 position;
layout(location = 1) in vec4 normal;
uniform mat4 modelM;
uniform mat4 cameraM;
uniform mat4 projectionM;
uniform vec3 normal;
uniform vec3 camPosition;
uniform vec3 lightPos;
out vec4 coll;
void main()
{
coll = vec4(1.0f,1.0f,1.0f,1.0f);
mat4 tmp1 = cameraM*modelM;
mat4 tmp2 = projectionM * tmp1;
gl_Position = tmp2 * position;
}

... ups, noticed the doubly named variable 'normal'. Changing it has made an immediate change to the better ..

hi again,
the error 'illegal counting' persists, but it does not knock the program out right away. It runs a good handful of seconds and displays what it's supposed to display, then pops a fatal error 1 (?) and says that too many errors has occurred. The errors are not caught in the application.
I counted the chars of the shader and it matches the right size. I display the shader-source in printf() and it's not garbled .. it adds a couple of blank lines in the console though.
I've changed a simple draw-triangle program (working perfectly with the same shader [and error?]) to display a height-field of 1201*1201 vertices (bitbanging to little-endian). I should go look for errors in that load and associated changes.

alas ..
Index and Vertex MAX_COUNT exceeded ;o/
