“的std :: basic_string的 <char,std::char_traits<char> ，性病::分配器 <char> > :: c_str'：非标准语法; 使用'＆'创建指向成员的指针
[英]'std::basic_string<char,std::char_traits<char>,std::allocator<char>>::c_str': non-standard syntax; use '&' to create a pointer to member
问题描述
I'm trying to make a function that can read and compile opengl vertex and fragment shader files, but I'm getting this error: 
我正在尝试创建一个可以读取和编译opengl顶点和片段着色器文件的函数，但是我收到了这个错误：
'std::basic_string<char,std::char_traits<char>,std::allocator<char>>::c_str': non-standard syntax; use '&' to create a pointer to member
I'm not quite sure how to fix it. 我不太清楚如何解决它。 Here is my code: 这是我的代码：
GLuint shader_load(const GLchar* vertex, const GLchar* fragment) {
std::string ver = file_read_all(vertex);
std::string frag = file_read_all(fragment);
const GLchar* verCode = ver.c_str;
const GLchar* fragCode = frag.c_str;
GLuint program;
GLuint verShader, fragShader;
GLint success;
GLchar log[512];
verShader = glCreateShader(GL_VERTEX_SHADER);
glShaderSource(verShader, 1, &verCode, NULL);
glCompileShader(verShader);
glGetShaderiv(verShader, GL_COMPILE_STATUS, &success);
if (!success) {
glGetShaderInfoLog(verShader, 512, NULL, log);
std::cout << "Failed to compile Vertex Shader\n" << log << std::endl;
return NULL;
}
fragShader = glCreateShader(GL_FRAGMENT_SHADER);
glShaderSource(fragShader, 1, &fragCode, NULL);
glCompileShader(fragShader);
glGetShaderiv(fragShader, GL_COMPILE_STATUS, &success);
if (!success) {
glGetShaderInfoLog(fragShader, 512, NULL, log);
std::cout << "Failed to compile Fragment Shader\n" << log << std::endl;
return NULL;
}
program = glCreateProgram();
glAttachShader(program, verShader);
glAttachShader(program, fragShader);
glLinkProgram(program);
glGetProgramiv(program, GL_LINK_STATUS, &success);
if (!success)
{
glGetProgramInfoLog(program, 512, NULL, log);
std::cout << "Failed to Link Shader\n" << log << std::endl;
}
glDeleteShader(verShader);
glDeleteShader(fragShader);
}

std::string::c_str is a member function, if you want to call it, you should add () . std::string::c_str是一个成员函数，如果你想调用它，你应该添加() 。
const GLchar* verCode = ver.c_str();
