R包中的错误＆＃34; igraph＆＃34;安装

Question

我试图安装R包＆＃34; igraph＆＃34;在Linux服务器上并遇到一些错误。

我已尝试install.packages("igraph")，并收到以下错误消息：

1. 与checking whether the C compiler works... no相关的问题：

   * installing *source* package ‘igraph’ ...
   ** package ‘igraph’ successfully unpacked and MD5 sums checked
   checking for gcc... /usr/local/bin/gcc
   checking whether the C compiler works... no
   configure: error: in `/tmp/RtmpPaaksz/R.INSTALL8c157a39a973/igraph':
   configure: error: C compiler cannot create executables
   See `config.log' for more details
   ERROR: configuration failed for package ‘igraph’
   

2. 与lazyeval.c:53: error: ‘for’ loop initial declarations are only allowed in C99 mode相关的问题：

   lazyeval.c: In function ‘make_lazy_dots’:
   lazyeval.c:53: error: ‘for’ loop initial declarations are only allowed in C99 mode
   lazyeval.c:53: note: use option -std=c99 or -std=gnu99 to compile your code
   lazyeval.c:63: error: redefinition of ‘nxt’
   lazyeval.c:53: note: previous definition of ‘nxt’ was here
   make: *** [lazyeval.o] Error 1
   ERROR: compilation failed for package ‘igraph’
   

我的环境是

• 的Linux
• R 3.4.3

有人会给我一些宝贵的建议吗？

由于我的问题的一致性，我关闭了这篇文章，尽管我仍然无法安装该软件包。谢谢大家！

Answer 1

我通过将〜/ .R / Makevars文件更改为

来处理两个问题

C=gcc-5
CXX=g++
CXX1X = g++-5
CFLAGS = -std=c99 -Wall -pedantic

前三行是问题1，最后一行是2。
