我尝试使用磁盘工具修复权限，并在 Xcode 中禁用了源代码控制。如果我只是删除对 SDL 的引用，问题就会消失。例如，以下程序最初可以运行，但是当我将项目链接到 SDL 时崩溃:

// #include <SDL2/SDL.h>
#include <iostream>
int main()
{
    std::cout << "Hello World!" << std::endl;
    return 0;
}

我在这里做错了吗？

最佳答案

看起来问题在于 SDL2 没有正确签名。有一张票可以在 https://bugzilla.libsdl.org/show_bug.cgi?id=2058 上解决此问题.

当您使用 lldb 从 Xcode 5 生成应用程序时，Xcode 会加载一个插件，该插件将检查您的应用程序加载的模块，大概是为了让您深入了解您的程序。如果 Xcode 从一个由无效签名支持的页面读取，它会被设置为崩溃。因为 SDL2 没有正确签名，所以当 Xcode 5 尝试检查 SDL2 库时，它将从无效页面读取并崩溃。您可以通过上面的崩溃报告中的以下行获得线索:

Exception Type:  EXC_BAD_ACCESS (Code Signature Invalid)

要亲自查看 SDL 未正确签名，请从 SDL2 所在的文件夹执行以下命令:

$ codesign -vvvv SDL2 
SDL2: invalid signature (code or signature have been modified)
In architecture: x86_64

如果您不想构建自己的 SDL2 版本(上面提到的解决方案)，您可以更新签名以使其正确:

$ codesign -f -s - SDL2 
SDL2: replacing existing signature

并验证新签名是否良好:

$ codesign -vvvv SDL2
SDL2: valid on disk
SDL2: satisfies its Designated Requirement

请注意，从安全角度来看，将其作为一种解决方法是有风险的，因为我不确定为什么签名无效。

关于使用 SDL 2 运行应用程序时 Xcode 5 崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22368202/
