如何使用c++；R窗口中的代码？

我有一个带有Rcpp代码的R包。在任何linux发行版中都可以正常构建。问题是在windows中构建它。我的设置中有以下内容

R版本4.0.1（2020-06-06）

Windows10Pro版本1903

Rtools 4.0安装在

C:\rtools40

这是Rgui的输出：

错误

/usr/bin/sh:line 8:“C:/rtools40/mingw64/bin/”g++-std=gnu++11:没有这样的文件或目录

是没有意义的，因为该目录存在。

我在

devtools

中找到了运气。我在github中上传了我的软件包，并使用

devtools:：install\u github（“myuser/my\u rcpp\u软件包”）

进行了安装。使用DeVoToice，可以在没有任何问题的情况下构建一个带有C++代码的R包。< /P>是安装在<代码>：/RoToS40/MIWW64／BI/<／代码>中的G+编译器。是的，它在那里。好的，但是请注意，代码> DEVToSoS/<代码>调用您已经安装的相同的基本编译器和工具。它可能“只是”设置了一个或两个您没有直接设置的环境变量。
