glGetShaderInfoLog返回Gibberish

Question

我在从openGL获取调试信息时遇到了一些问题。我不知道它是否有任何区别，但我正在使用glfw3和glew（动态链接）

我似乎无法编译着色器和我得到的错误消息只是胡言乱语。

以下是示例代码：

shader.ID = glCreateShader(shader.type);
const GLchar *source = (const GLchar *)shader.source.c_str();
glShaderSource(shader.ID, 1, &source, 0);
glCompileShader(shader.ID);
GLint compiled = 0;
glGetShaderiv(shader.ID, GL_COMPILE_STATUS, &compiled);
if (compiled == GL_FALSE) {
    GLint logLength = 0;
    glGetShaderiv(shader.ID, GL_INFO_LOG_LENGTH, &logLength); //won't update logLength
    //std::cout << logLength << std::endl;
    GLchar* infoLog = new char[logLength + 1];
    glGetShaderInfoLog(shader.ID, logLength, NULL, infoLog);
    std::cerr << infoLog << std::endl;
    delete[] infoLog;
    glDeleteShader(shader.ID);
}

glGetShaderiv 不会更新logLength，我得到的输出将是这样的：

这是我第一次尝试编译着色器，我错过了什么？

编辑：上下文创建

#include <GL\glew\glew.h>
#include <GL\GLFW\glfw3.h>

void setupGLFW() {
    //glfwSetErrorCallback(glfwErrorCallback);
    if (GL_FALSE == glfwInit()) {
        std::cerr << "Error Initializing GLFW" << std::endl;
        exit(-1);
    }
    GLFWwindow* window = glfwCreateWindow(640, 480, "TEST", NULL, NULL);
    glfwMakeContextCurrent(window);
    glfwSwapInterval(1); 
}

void setupGLEW() {
    glewExperimental = GL_TRUE;
    const GLenum glewErr = glewInit();
    if (glewErr != GLEW_OK) {
        cerr << "GLEW failed to initialize." << endl;
        exit(-1);
    }
}
void testshaderLoader()
{
    setupGLFW();
    setupGLEW();
    glEnable(GL_DEBUG_OUTPUT);
    ShaderLoader sloader;
    string pathToShader = "absolute/path/to/shader"
    GLenum shaderType = GL_FRAGMENT_SHADER;
    sloader.loadShader(pathToShader, shaderType);
}
int main()
{
    testshaderLoader();
    return 0;
}
