在Cygwin下在Windows中构建R软件包 [英] Build R package in Windows under Cygwin

问题描述

当尝试在Cygwin下从Win10上的源将R软件包dplyr更新到0.7.0时(dplyr 0.7.0的Windows二进制文件不可用.我的R安装不在Cygwin下，我的R安装来自二进制文件).但是当我跑步

When trying to update R package dplyr to 0.7.0 from source on Win10 under Cygwin (windows binary for dplyr 0.7.0 is not available. Also my R installation in not under Cygwin and my R installation is from binary). However when I run

R CMD INSTALL dplyr_0.7.0.tar.gz

看到以下错误:

* installing to library 'C:/Program Files/R/R-3.4.0/library'
* installing *source* package 'dplyr' ...
** package 'dplyr' successfully unpacked and MD5 sums checked

错误原因是R(使用Rtools库)在c:/Rtools/mingw_64/bin/下而不是Cygwin/usr/bin/

The cause of error is R (using Rtools library) looks for g++/gcc compilers under c:/Rtools/mingw_64/bin/ and not under Cygwin /usr/bin/

是否可以更改R CMD INSTALL的默认行为，从而允许在没有Rtoools的情况下在Windows中从源代码构建R包?

Is there a way to change this default behavior of R CMD INSTALL which would allow building R packages from source in Windows without Rtoools?

谢谢

PS.我认为这篇文章您如何使用cygwin从源代码编译R包?是相关的，但看来R已安装在Cygwin下，这不是我的情况.

PS. I think this post how do you use cygwin to compile an R package from source? is relevant, but it appears R was installed under Cygwin, which is not my case.

PPS.看来我需要更改在

PPS. It appears I need to change variables defined under

R CMD config

有什么想法吗?

推荐答案

我不确定什么是最好的解决方案.但是您当然可以通过修改 $(R_HOME)/etc/x64/Makeconf 中的BINPREF来解决此问题. c:/Rtools/mingw_64/bin/是默认值.

I'm not sure what the best solution is. But you can certainly fix this by modifying BINPREF in $(R_HOME)/etc/x64/Makeconf. c:/Rtools/mingw_64/bin/ is the default value.

PS:您几乎可以肯定 可以使用cygwin编译器来构建R包，只要只涉及C链接即可.我在Visual Studio下构建了我的一些.

PS: You almost certainly can use the cygwin compiler to build R packages, as long as only C linkage is involved. I build some of mine under Visual Studio.
