当我尝试install.packages('readr')时，我会收到来自
clang++ -I/usr/local/lib/R/include -DNDEBUG -I/usr/local/lib/R/include
-I/usr/local/include -I"/usr/local/lib/R/site-library/Rcpp/include"
-I"/usr/local/lib/R/site-library/BH/include"
-fpic -g -O2 -O3 -fstack-protector --param=ssp-buffer-size=4
-Wformat -Wformat-security -Werror=format-security
-D_FORTIFY_SOURCE=2 -g -std=c++11
-c Collector.cpp -o Collector.o
我正在检查~/.R/Makevars和/etc/R/Makeconf是否可以设置此clang++ -I....命令但不包含该语言。
echo $CXX
echo $CC
都是空的，并且在开始R之前将它们设置为其他内容并没有帮助。开始R --no-environ也不会更改错误消息。
那么可以设置这些环境变量的位置，如何更改或禁用它们，以及如何在下一次从某个地方找出这个＆＃34;全局变量＆＃34;错误来自？
提前致谢。
答案 0 :(得分：0)
我可能需要to add导出LIBRARY_PATH = / opt / boost_1_61_0 / boost / to my〜/ .bashrc`。
这不回答我的问题（关于如何清除clang来电），而是将CXX中的~/.R/Makevars值从clang++更改为g++确实修复了我无法安装readr的直接问题。
以下是clang下的构建错误：

如果我使用g++代替clang++进行编译，则错误会成为警告：

（错误太长，粘贴在http://ix.io/11F0）
所以两个编译器都不喜欢spirit和fusion（用我选择的标志，我仍然无法弄清楚如何清理）。
