Getting garbage chars when reading GLSL files

Question

I run into the following problem.I load my shaders from files.The shader program ,when trying to compile, throws these errors for the vertex and fragment shaders:

V

You're using C++, so I suggest you leverage that. Instead of reading into a self allocated char array I suggest you read into a std::string:

#include 
#include 

std::string loadFileToString(char const * const fname)
{
    std::ifstream ifile(fname);
    std::string filetext;

    while( ifile.good() ) {
        std::string line;
        std::getline(ifile, line);
        filetext.append(line + "\n");
    }

    return filetext;
}

That automatically takes care of all memory allocation and proper delimiting -- the keyword is RAII: Resource Allocation Is Initialization. Later on you can upload the shader source with something like

void glcppShaderSource(GLuint shader, std::string const &shader_string)
{
    GLchar const *shader_source = shader_string.c_str();
    GLint const shader_length = shader_string.size();

    glShaderSource(shader, 1, &shader_source, &shader_length);
}

void load_shader(GLuint shaderobject, char * const shadersourcefilename)
{
    glcppShaderSource(shaderobject, loadFileToString(shadersourcefilename));
}
