从源代码安装 R 代码时出现 g++ 错误 [英] Getting g++ error when installing R code from source

问题描述

我已经从 CRAN 下载了 Rcpp 并将其解压缩并尝试构建它.当我尝试使用 R CMD INSTALL 时.在我得到的目录中:

I've downloaded Rcpp from CRAN and unzipeed it and attempted to build it. When I try to use R CMD INSTALL . in the directory I get:

cp: unknown option -- )

如果我尝试打开一个会话并使用 install.packages("Rcpp", type = "source")，我会从 g++ 收到以下错误:

If I try to open up a session and use install.packages("Rcpp", type = "source"), I get the following error from g++:

*** arch - x64
g++ -m64 -I"C:/R/R-30~1.1/include" -DNDEBUG -I../inst/include/    -I"d:/RCompile/CRANpkg/extralibs64/local/include"     -O2 -Wall  -mtune=core2 -c Date.cpp -o Date.o
Date.cpp:1:0: sorry, unimplemented: 64-bit mode not compiled in
make: *** [Date.o] Error 1

我安装了 Rtools，它的目录在我的路径前面.我使用的是 64 位 Windows 7.是否有我缺少的安装选项?我一直在阅读 R 的安装和管理手册的附录 D，但找不到我可能违反的任何内容，所有内容都是通过 Rtools 安装的.我觉得有一个标志我没有包括在内，但我不知道是什么.

I have Rtools installed, and its directories are in the front of my path. I am on 64-bit Windows 7. Are there install options that I am missing? I have been reading appendix D of R's Installation and Administration manual and can't find anything I might have violated, everything was installed through Rtools. I feel like there is a flag that I am not including but I can't figure out what.

推荐答案

这个问题在我按连续顺序执行以下操作(我不确定是哪一个修复它)后开始起作用:

This problem started working once I did the following (I'm not sure which one fixed it) listed in consecutive order:

-把我的咖啡杯扔到墙上，诅咒德克·埃德尔比特尔

-threw my coffee cup against the wall, cursing Dirk Eddelbuettel

-将 R 路径变量从 C:R\R-3.0.1\bin 更改为 C:\R\R-3.0.1\bin\x64\

-changed the R path variable from C:R\R-3.0.1\bin to C:\R\R-3.0.1\bin\x64\

-重新安装Rtools，这次勾选允许它更改系统路径的框，我之前一直在更改我的用户路径

-reinstalled Rtools, this time checking the box allowing it to change the system path, I had been changing my user path before

-请求 Dirk Eddelbuettel 的灵魂原谅

-asked the spirit of Dirk Eddelbuettel for forgiveness

-重启Rstudio

它奏效了.我想这是因为我没有考虑系统路径，它首先在 windows 中读取，所以它运行到了一个 Haskell g++ 编译器中，它在所有东西的前面，而且只有 32 位.

It worked. I think it was because I was not considering the system path, which is read first in windows, and so it was running into a Haskell g++ compiler, which was in front of everything, and only 32 bit.
