Title: Help in C++ please
Post by: Electronics Boy on May 03, 2021, 06:26:51
Hi! i know that i should not post this here, but i did not find any other website(Yes, i tryed to post in stackoverflow but got my account terminated for no reason).

so this is the error log:

i dont know why

here is the code for shader.cpp:

Code Select

#include "StaticShader.h"
#include "GL/glut.h"

StaticShader::StaticShader() {
    StaticShader::vertexShaderID = StaticShader::loadShader(StaticShader::vertexShader, GL_VERTEX_SHADER);
    StaticShader::fragmentShaderID = StaticShader::loadShader(StaticShader::fragmentShader, GL_FRAGMENT_SHADER);

    StaticShader::programID = glCreateProgram();

    glAttachShader(StaticShader::programID, vertexShaderID);
    glAttachShader(StaticShader::programID, fragmentShaderID);

    glBindAttribLocation(StaticShader::programID, 0, "position");

    glLinkProgram(StaticShader::programID);
    glValidateProgram(StaticShader::programID);
}

void StaticShader::start() {
    glUseProgram(StaticShader::programID);
}
void StaticShader::stop() {
    glUseProgram(0);
}

GLuint StaticShader::loadShader(string shaderSource, GLenum type) {
    GLuint shader = glCreateShader(type);

    glShaderSource(shader, 1, shaderSource, sizeof(shaderSource));
    glCompileShader(shader);
    if(!glGetShaderi(shader, GL_COMPILE_STATUS)) {
        cout << "Unable to compile shader!" << endl;
        exit(-1);
    }
    return shader;
}


and for shader.h:
Code Select

#ifndef STATICSHADER_H
#define STATICSHADER_H

#include "GL/glut.h"
#include <iostream>

using namespace std;

class StaticShader
{
    public:
        StaticShader();
        void start();
        void stop();
    protected:
        GLuint loadShader(string shaderSource, GLenum type);

        string vertexShader = string("#version 150")      +
                              string("in vec3 position;") +
                              string("out vec3 colour;")  +

                              string("void main(void) {")  +
                              string(  "gl_Position = vec4(position,1.0);")  +
                              string(  "colour = vec3(position.x+0.5,0.0,position.y+0.5);") +
                              string("}");

        string fragmentShader = string("#version 150") +
                                string("in vec3 colour;") +
                                string("out vec4 out_Color;") +

                                string("void main(void) {") +
                                string("    out_Color = vec4(colour,1.0);") +
                                string("}");

        GLuint vertexShaderID;
        GLuint fragmentShaderID;

        GLuint programID;
    private:
};

#endif // STATICSHADER_H


for the other classes, please ask for it, i will send a link for them

You ask help for C++ on a java library forum, and even after fixing your C++ code, you donââ,¬â,,¢t post the solution. Congrats!
