Question

试图弄清楚如何在Objective-C ++中使用BGL。有点不对劲。重现的步骤：

新的Cocoa应用程序项目。
将MyAppDelegate.m重命名为MyAppDelegate.mm
将#include <boost/shared_ptr.hpp>添加到MyAppDelegate.mm（工作正常，假设您的标题搜索路径设置正确。）
将#include <boost/graph/adjacency_list.hpp>添加到MyAppDelegate.mm

boost/graph/adjacency_list.hpp传递包含的内容与Cocoa标头可传递导入的一些旧的Carbon标头发生冲突。这是我看到的输出（无论如何第一个错误的价值）：

如果我从项目的前缀标题中删除#import <Cocoa/Cocoa.h>，然后在MyAppDelegate.mm中包含#include <boost/graph/adjacency_list.hpp>之前<Cocoa/Cocoa.h>，则会编译，但这是次优/不合适的。< / p>

我能做些简单的事情（理想情况是在前缀标题中，所以我不必在任何地方都这样做）使Cocoa标题和BGL标题和平共存吗？

Answer 1

在询问之前，应该用Google搜索 epsilon 更多时间。发布之后我发现this page，这解释了在包含Cocoa标题之前添加以下行将会起到作用：

#define __ASSERT_MACROS_DEFINE_VERSIONS_WITHOUT_UNDERSCORES 0

我曾尝试在我的个人MyAppDelegate.mm文件中执行此操作，但它不起作用，但这是因为前缀标题。
