Question

当尝试在Cygwin下的Win10上从源代码更新R包dplyr到0.7.0时（dplyr 0.7.0的windows二进制文件不可用。另外我的R安装不在Cygwin和我的R安装下来自二进制）。但是当我跑步时

R CMD INSTALL dplyr_0.7.0.tar.gz

请参阅以下错误：

* installing to library 'C:/Program Files/R/R-3.4.0/library'
* installing *source* package 'dplyr' ...

错误原因是R（使用Rtools库）在c：/ Rtools / mingw_64 / bin /下查找g ++ / gcc编译器，而不是在Cygwin / usr / bin /

下

有没有办法改变R CMD INSTALL的默认行为，这样可以在没有Rtoools的Windows中从源代码构建R包？

由于

PS。我想这篇文章 how do you use cygwin to compile an R package from source? 是相关的，但似乎R安装在Cygwin下，这不是我的情况。

PPS。看来我需要更改

下定义的变量

R CMD config

任何想法如何？

我不确定最佳解决方案是什么。但你可以通过修改$(R_HOME)/etc/x64/Makeconf中的BINPREF来解决这个问题。 c:/Rtools/mingw_64/bin/是默认值。

PS：你几乎可以肯定可以使用cygwin编译器构建R包，只要涉及C链接。我在Visual Studio下构建了一些我的。
