gnu gcc如何禁止警告：'typedef'在此声明中被忽略[默认启用] [英] gnu gcc How to suppress warning: ‘typedef’ was ignored in this declaration [enabled by default]

问题描述

我在Fedora 16上使用GNU gcc 4.6.2。我正在使用第三方API编写应用程序，编译后，我收到了很多警告。

 警告：在此声明中忽略typedef[默认启用] 
  

只是想知道如何抑制这个？我用-Wall标志编译程序。

在本文档中， http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html ，它提到了类似 -Wunused-local-typedefs 。

我尝试了 -Wno-unused-local-typedefs ，但无效。

谢谢。

解决方案

-Wno-unused-local- typedefs适用于gcc 4.8。 >

I am using GNU gcc 4.6.2 on Fedora 16. I am writing an application using a 3rd party API, after compilation, I got a lot warnings.

warning: ‘typedef’ was ignored in this declaration [enabled by default]

Just wondering how can I suppress this? I compile my program with -Wall flag.

In this doc, http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html, it mentioned something like -Wunused-local-typedefs.

I have tried -Wno-unused-local-typedefs, but doesn't work.

Thanks.

解决方案

-Wno-unused-local-typedefs works in gcc 4.8 for me.
