我使用libcurl,我得到这些错误,而没有编写任何代码只是编译,我不知道为什么

Fehler  49  error C2628: '$UnnamedClass$0x05e5b255$395$' gefolgt von 'bool' unzulässig (Semikolon ';' vergessen?)   c:\users\ttg\desktop\curl-7.21.7\lib\setup_once.h   273
Fehler  50  error C2065: '_SH_DENYNO': nichtdeklarierter Bezeichner C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\xiosbase  111

首先是一个libcurl文件,它说它后面跟bool(忘了分号？)

第二个未声明的标识符

这是整个代码

#pragma once

#include <curl/easy.h>

如何从QNetworkReply中读取标题,例如cookie？

我想在C中编译客户端以进行Redis。我已经下载并安装了libevent库和hiredis文件。我使用了以下命令：

gcc -I/home/tasos/Dropbox/lists/hiredis example-libevent.c -levent

但我得到这些错误：

example-libevent.c:(.text+0x28): undefined reference to `redisAsyncHandleRead'

为什么这不起作用？

我怎么能不断检查鼠标是否已经关闭,鼠标是否已经关闭并且它移动了我的功能

我试过mk_mc.addEventListener(MouseEvent.MOUSE_DOWN,fct)但它只调用功能然后停止,我想不断地做,我怎么能这样做？
