R Makevars文件未正确覆盖g ++

时间：2018-02-14 20:59:00

标签： c++ r rstudio

我试图安装R套餐＆＃39; lubridate＆＃39;因为lubridate需要比Centos 6上的标准编译器更新版本的g ++，我下载并编译了版本gcc 4.9（从我读过的内容来看，lubridate需要＆gt; v4.8）

然后我添加了一行：

CXX=/opt/gcc_4.9.1/rtf/bin/g++
CC=/opt/gcc_4.9.1/rtf/bin/gcc -std=gnu99

到〜/ .R / Makevars文件，尝试强制它使用更新的编译器，但是当我尝试安装lubridate时出现此错误：

有趣的是，它似乎正在尝试正确使用正确的gcc：

/opt/gcc_4.9.1/rtf/bin/gcc -std=gnu99 -I/opt/R/R-3.3.3/include -DNDEBUG -I. -I./cctz/include/ -I./cctz/src/ -I/usr/local/include -I"/opt/R/R-3.3.3/library/Rcpp/include"  -O3 -Wall -pipe -pedantic -std=gnu99 -fopenmp -fpic  -O3 -Wall -pipe -pedantic -std=gnu99 -fopenmp -c datetime.c -o datetime.o

但不是正确的g ++（没有列出我在〜/ .R / Makevars文件中定义的完整路径）：

g++ -std=c++0x -I/opt/R/R-3.3.3/include -DNDEBUG -I. -I./cctz/include/ -I./cctz/src/ -I/usr/local/include -I"/opt/R/R-3.3.3/library/Rcpp/include"   -fpic  -g -O2 -c RcppExports.cpp -o RcppExports.o

如果我将〜/ .R / Makevars文件中的行更改为：

CXX=g++
CC=gcc

然后看起来两个可执行文件都成为正常的系统：

g++ -std=c++0x -I/opt/R/R-3.3.3/include -DNDEBUG -I. -I./cctz/include/ -I./cctz/src/ -I/usr/local/include -I"/opt/R/R-3.3.3/library/Rcpp/include"   -fpic  -g -O2 -c RcppExports.cpp -o RcppExports.o
gcc -I/opt/R/R-3.3.3/include -DNDEBUG -I. -I./cctz/include/ -I./cctz/src/ -I/usr/local/include -I"/opt/R/R-3.3.3/library/Rcpp/include"  -O3 -Wall -pipe -pedantic -std=gnu99 -fopenmp -fpic  -O3 -Wall -pipe -pedantic -std=gnu99 -fopenmp -c datetime.c -o datetime.o

是否有另一个文件优先于〜/ .R / Makevars文件中定义的g ++位置？真正的问题是如何让R在这里使用/opt/gcc_4.9.1/rtf/bin/g++？

1 个答案:

答案 0 :(得分：0)

看来我需要在〜/ .R / Makevars文件中设置CXX1X=/opt/gcc_4.9.1/rtf/bin/g++，之后rubridate包使用了预期的g ++，并成功编译。不幸的是，由于R无法加载库，这还没有完全解决我的问题：

** testing if installed package can be loaded
Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared object '/opt/R/R-3.3.3/library/lubridate/libs/lubridate.so':
  /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.18' not found (required by /opt/R/R-3.3.3/library/lubridate/libs/lubridate.so)
Error: loading failed
Execution halted
ERROR: loading failed
* removing ‘/opt/R/R-3.3.3/library/lubridate’

看起来R正在使用/usr/lib64/libstdc++.so.6，而不是（可能是？）使用/opt/gcc_4.9.1/rtf/lib64/libstdc++.so.6。但它确实解决了我在这里问的问题。如果我能弄清楚如何加载它，我会在这里回复，以防其他人试图做同样的事情。感谢RolandASc指出我正确的方向。
