配置：错误：缺少所需的libcurl

Question

我试图编译的需要curllib的Windows XP 32位项目

我已经下载了“curl-7.35.0.tar.gz”和编译它，复制的“libcurl.m4”和“curl-config”

当我运行在MSYS壳下面的命令：

LIBCURL="-lcurldll" ./configure CFLAGS="-O3" 

它给了我这个错误：

configure: error: Missing required libcurl >= 7.15.2 

我知道，我还没有在我的系统正确安装卷曲的lib这就是为什么这个错误显示出来

有人可以告诉我在windows安装libcurl的正确方法是什么？ （注：我是一个C/C + +和编译和所有相关的东西新手）

在此先感谢！

你需要你下载的libcurl /在接头路径编译。这意味着您需要将libcurl.dll文件（而不是m4）放到链接程序将搜索的目录中。通常是项目目录或Windows中默认定义的系统库之一。
