问题描述
我使用libcurl，我得到这些错误，没有写任何代码只是编译，我不知道为什么
Fehler 49错误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错误C2065：'_SH_DENYNO'：nichtdeklarierter Bezeichner C：\Program Files（x86）\Microsoft Visual Studio 9.0 \VC\include \xiosbase 111
首先是libcurl文件，它后面跟着bool（forgot semicolon？）
第二个未声明的标识符
这是整个代码

这是第二个问题的解释：

错误C2065：'_SH_DENYNO'：未声明的标识符
参见正在编译的类 - 模板的实例化
$ b因为在libCURL中有一个名为 share.h 的文件。 $ b
解决方案
$ b
您应将其重命名为 curl_share.h
&全部取代
#includeshare.h
由
#includecurl_share.h
I use libcurl and I get these errors without writting any code just compiling and I don't know why

first is a libcurl file and it says it's followed by bool(forgot semicolon?)
second undeclared identifier
this is the whole code

that's the explanation for second problem:

translation
error C2065: '_SH_DENYNO': undeclared identifier
See reference to the instantiation of the classes-template being compiled
解决方案
Because of there's a file named share.h in libCURL.
You should rename it into curl_share.h & replace all
#include "share.h"
by
#include "curl_share.h"
