r - 在 Windows 上从源代码编译 RCurl

Question

由于 v1.95-4.3 还没有 Windows 二进制文件，我需要安装/编译 RCurl Windows 8.1 上的源代码包。 (64 位)。

谁能告诉我

1. 哪个版本cURL我需要
2. libcurl.dll等各种文件需要准确放置的地方

下面错误信息中提到的x64目录是否对应R安装的x64目录？

非常感谢!

看起来适用于 Windows 的 RCurl v1.95-4.3 二进制文件已于今天早上上传到 CRAN。我正在处理与您完全相同的问题，在从源代码构建二进制文件后，我再次使用 RCurl 时一切正常!

http://cran.r-project.org/web/packages/RCurl/index.html

install.packages("RCurl_1.95-4.3.zip", repos=NULL, type="source")
