我尝试使用磁盘工具修复权限，并且在Xcode中禁用了源代码管理。如果我简单地删除对SDL的引用，问题消失。例如，以下程序最初工作，但当我将项目链接到SDL时崩溃：
// #include< SDL2 / SDL.h>
#include< iostream>
int main（）
{
std :: cout< 你好，世界！ << std :: endl;
return 0;
}
我在这里做错了吗？
解决方案
看起来问题是SDL2没有正确签名。有一个问题需要修复，请访问 https://bugzilla.libsdl.org/show_bug.cgi?id=2058 。
当使用lldb从Xcode 5生成应用程序时，Xcode会加载一个插件，用于检查应用程序加载的模块， 。 Xcode设置为在从由无效签名支持的页面读取时崩溃。因为SDL2没有正确签名，当Xcode 5尝试检查SDL2库时，它将从无效的页面读取并崩溃。您可以通过上面的崩溃报告中的以下行获得线索：
异常类型：EXC_BAD_ACCESS（代码签名无效）
要自己看看SDL没有正确签名，请从文件夹中执行以下命令SDL2位于：
$ codesign -vvvv SDL2
SDL2：无效的签名（代码或签名已修改）
在架构中：x86_64
如果您不想构建自己的SDL2版本您可以更新签名以使其正确：
$ codesign -f -s - SDL2
SDL2：替换现有的签名
并验证新签名是否正确：
$ codesign -vvvv SDL2
SDL2：磁盘上有效
SDL2：满足其指定的要求
请注意，从安全的角度来看，这是一个解决方法是有风险的，因为我不知道为什么签名是无效的。 / p>

I've tried to repair permissions using the Disk Utility and also disabled Source Control in Xcode. The problem disappears if I simply delete the reference to SDL. For example the following program works initially, but crashes when I link the project to SDL:
// #include <SDL2/SDL.h>
#include <iostream>
int main()
{
std::cout << "Hello World!" << std::endl;
return 0;
}
Am I doing something wrong here?
解决方案
It looks like the problem is that SDL2 isn't properly signed. There's a ticket to fix the issue at https://bugzilla.libsdl.org/show_bug.cgi?id=2058.
When you spawn an application from Xcode 5 with lldb, Xcode loads a plugin that will inspect modules your application loads, presumably to give you insight into your program. Xcode is set up to crash if it reads from a page that is backed by an invalid signature. Because SDL2 isn't properly signed, when Xcode 5 attempts to examine the SDL2 library, it will read from an invalid page, and crash. You get a clue that this is happening by the following line in your crash report above:
Exception Type: EXC_BAD_ACCESS (Code Signature Invalid)
To see for yourself that SDL isn't properly signed, execute the following command from the folder where SDL2 resides:
$ codesign -vvvv SDL2
SDL2: invalid signature (code or signature have been modified)
In architecture: x86_64
If you don't want to build your own version of SDL2 (the solution that's mentioned above), you can update the signature to make it correct:
$ codesign -f -s - SDL2
SDL2: replacing existing signature
And to verify that the new signature is good:
$ codesign -vvvv SDL2
SDL2: valid on disk
SDL2: satisfies its Designated Requirement
Note that doing this as a workaround is risky from a security standpoint, as I'm not sure why the signature is invalid.
