c++ - 无法解析基于模板的标识符 "get".Netbeans 8.1

Question

我的问题是:

我收到了帖子主题中显示的警告。这真是令人沮丧。 自动完成 不适用于代码，旁边会出现警告。 标准设置为 C++14。

例如:

 Boxes[2].get()->setPosition(Boxes[2].get()->getPosition() + v1);

它给了我一个警告，当我尝试编写另一个 Boxes[2] 时。autocomplete 不起作用。

一个对象的声明:

<shared_ptr<ofxBox2dRect>> Boxes;

我尝试使用这些链接解决我的问题:

1. Unable to resolve identifier on netbeans
2. “Unable to resolve identifier” , although build is successful

还有很多，但它们对我没有帮助:(我重复了项目等)

我的 NetBeans 版本是 8.1，C++ 插件 1.29.6.1 在 Apricity OS 上运行。

我做了一些研究，我也收到了一些其他警告，我认为它们与我的问题有关。

Ctrl+Alt+Click to open include hierarchy

在我看来这个警告是最重要的:

Library File /usr/include/boost/smart_ptr/shared_ptr.hpp 
but there is an recursion #include <boost/predef/os/bsd.h> in included /usr/include/boost/predef/os/bsd/free.h 
Use Ctrl+Alt to show analyzed paths Ctrl+Alt+Click to open file with failed include directive

我花了几个小时试图解决我的问题。我按照上面给出的链接中介绍的步骤进行操作，但它们对我没有帮助。希望在那里我能找到帮助。

对我来说最重要的是接收完全可用的自动完成。

我得到了自动完成 ON，它工作正常，但在这个特殊情况下不是。

我认为这可能是命名空间的问题，所以添加 using namespace std;我重建、清理并重现了该项目，但没有帮助。;(

感谢您的帮助；)

Answer 1

我遇到了同样的问题。问题在于 boost predef/os/bsd.h header 。它在 #ifndef BOOST_PREDEF_OS_BSD_H 守卫的#else block 中#includes 5 个文件。这意味着如果这 5 个文件中的任何一个还包含 bsd.h(它们包含)，则此头文件无法防止递归。

我的解决方案是编辑 predef/os/bsd.h 文件并在 #else block 中添加递归保护 - 因此，从第 94 行开始，我的 predef/os/bsd.h 文件现在看起来像:

#ifndef BOOST_PREDEF_OS_BSD_H_PREVENT_RECURSION      <-- ADD THIS
#define BOOST_PREDEF_OS_BSD_H_PREVENT_RECURSION      <-- ADD THIS

#include <boost/predef/os/bsd/bsdi.h>
#include <boost/predef/os/bsd/dragonfly.h>
#include <boost/predef/os/bsd/free.h>
#include <boost/predef/os/bsd/open.h>
#include <boost/predef/os/bsd/net.h>

#endif                                               <-- ADD THIS

现在 netbeans 代码帮助很开心，我的代码仍然可以正确链接和编译。
