无法在Ubuntu 11.04上使用gcc 4.5编译boost :: signal教程 [英] Can not compile boost::signal tutorial using gcc 4.5 on ubuntu 11.04

问题描述

我正在尝试通过 http://www.boost.org/doc/libs/1_47_0/doc/html/signals/tutorial.html#id2850736

无论如何，Eclipse CDT都会显示我使用的任何语法的解析错误

However Eclipse CDT shows parsing errors with whichever syntax I use

我有

#include <boost/signals.hpp>

首选语法

boost::signal<void (float, float)> sig;    
sig.connect(&print_sum);

信号

无法解决方法连接"

便携式语法

boost::signal2<float, float, float> sig;
sig.connect(&print_sum);

无法解决方法连接"

Method 'connect' could not be resolved

符号"signal2"无法解析

Symbol 'signal2' could not be resolved

我使用eclipse 3.7

推荐答案

这似乎是CDT问题.您最近是否更新了Eclipse版本? eclipse论坛中正在进行关于该主题的讨论:

It seems to be a CDT issue. Have you updated your eclipse version lately? There is a discussion on that topic in the eclipse forum going on:

http://www.eclipse.org/forums/index.php/t/216821/

也许它给您一些有关如何解决该问题的启发.

Maybe it gives you some inspiration on how to work around that problem.

作为临时替代方法，您可以禁用某些代码分析功能和标记.为此，请转到窗口"->首选项"->"C/C ++"->代码分析"，并禁用部分或全部问题.我已禁用所有功能，因为它仍会突出显示在编译过程中发现的错误，并且不会因错误声明的问题而感到困惑.

As a temporary work around, you can disable certain code analysis features and markers. To do so, go to Window->Preferences->"C/C++"->"Code Analysis" and disable some or all problems. I have disabled all, since it will still highlight errors found during the compilation and I will not be confused by falsely declared problems.
