配置：错误：缺少所需的 libcurl

Question

我正在尝试在 windows xp 32 位上编译需要 curllib 的项目

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

当我在 MSYS Shell 中运行此命令时：

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

它给了我这个错误：

configure: error: Missing required libcurl >= 7.15.2

我知道我没有在我的系统中正确安装 curl 库，这就是出现此错误的原因

有人能告诉我在 windows 中安装 libcurl 的正确方法吗？ （注意：我是 C/C++ 和编译和所有相关内容的新手）

提前致谢！

您需要将下载/编译的 libcurl 放在链接器路径中。这意味着您需要获取 libcurl.dll 文件（而不是 m4）并将其放在链接器将搜索的目录中。通常是项目目录或 Windows 默认定义的系统库之一。
