如何使用选项 -std=c99 安装 R 包

我在安装 plyr R 包时遇到问题，并收到以下错误：

Installing package into '/home/mousavian/R/x86_64-pc-linux-gnu-library/3.2'
(as 'lib' is unspecified)

当尝试通过 install.packages 命令从源安装 R 软件包时，如何使用 -std=c99 选项？

Thanks

Try C11 First

编译器错误告诉您选择C99 or C11。因此，除非您有意编译遗留代码，否则请尝试C11第一的。您可以随时尝试旧版C99如果那不起作用。

Use withr::with_makevars

对于未来来说，编辑单个包 Makevars 或协调对每个不直接从源代码编译的包的 include/lib 目录的全局更改并不是一个好的策略。不要那样做！编辑 R 的绝佳替代方案make配置是使用withr::with_makevars来操纵Makevars仅适用于安装命令：

library(withr)

with_makevars(c(PKG_CFLAGS = "-std=c11"), 
              install.packages("plyr", repos = NULL, type = "source"), 
              assignment = "+=")

另外，您可能已经拥有withr安装，因为它是devtools依赖性。
