Clang 8发行说明中有以下内容：
- 允许在MinGW上使用Address Sanitizer和Undefined Behavior Sanitizer。
但是，我无法弄清楚如何正确使用它们。
我将Clang 8.0.0与MSYS2 MinGW GCC结合使用。确切的细节在问题的底部。
我正在尝试编译以下最少的代码：
1.cpp
#include <iostream>
int main()
{
// Testing ubsan
int x = 0x7fffffff;
x++;
std::cout << x << std::endl;
// Testing asan
int *y = new int;
delete y;
std::cout << *y << std::endl;
}
以下是结果-fsanitize=address：
# /z/Lander/LLVM/bin/clang++ -target x86_64-w64-windows-gnu -fsanitize=address 1.cpp
Z:\Lander\msys2\mingw64\bin\ld.exe: cannot find Z:\Lander\LLVM\lib\clang\8.0.0\lib\windows\libclang_rt.asan_dynamic-x86_64.dll.a: No such file or directory
Z:\Lander\msys2\mingw64\bin\ld.exe: cannot find Z:\Lander\LLVM\lib\clang\8.0.0\lib\windows\libclang_rt.asan_dynamic_runtime_thunk-x86_64.a: No such file or directory
Z:\Lander\msys2\mingw64\bin\ld.exe: cannot find Z:\Lander\LLVM\lib\clang\8.0.0\lib\windows\libclang_rt.asan_dynamic_runtime_thunk-x86_64.a: No …有了这个环境,我编译了一个在线发布的c ++/openGL示例:
#define GLEW_STATIC
// third-party libraries
#include <windows.h>
#include <GL/glew.h>
#include <GL/glfw.h>
#include <glm/glm.hpp>
#include <cassert>
#include <iostream>
#include <stdexcept>
GLuint gVAO = 0;
GLuint gVBO = 0;
GLuint programId;
const glm::vec2 SCREEN_SIZE(800, 600);
static void LoadTriangle() {
// make and bind the VAO
glGenVertexArrays(1, &gVAO);
glBindVertexArray(gVAO);
// make and bind the VBO
glGenBuffers(1, &gVBO);
glBindBuffer(GL_ARRAY_BUFFER, gVBO);
// Put the three triangle verticies …我知道有人问过类似的问题，但没有一个答案对我有帮助。
我编写了一个简单的SDL程序：
#include "SDL.h"
int main( int argc, char* args[] )
{
//Start SDL
SDL_Init( SDL_INIT_EVERYTHING );
//Quit SDL
SDL_Quit();
return 0;
}
使用代码：块。我遵循了本教程http://lazyfoo.net/SDL_tutorials/lesson01/windows/codeblocks/index.php， 但仍然无法编译。这是构建日志：

任何的想法？
