GLEW 1.10：glewInit中的EXC_BAD_ACCESS

Question

尝试初始化最近的GLEW，程序中断，lldb给出上述消息。

最小例子：

#define GLEW_STATIC
#include <GL/glew.h>

int main(int argc, const char * argv[]) {
    glewExperimental = GL_TRUE;
    glewInit();    <<<< EXC_BAD_ACCESS here
}

堆栈构成调试器输出：

1 ___lldb_unnamed_function...：

GLEW或我的配置中出现了这个错误吗？

Answer 1

显然，首先需要创建gl上下文。

因此，如果是glfw，则glfwCreateWindow需要成功调用glewInit。
