r - loop_apply.o : file not recognized: File format not recognized

Question

我正在尝试安装 R 的 plyr 包。这是错误消息:

* installing *source* package ‘plyr’ ...
** package ‘plyr’ successfully unpacked and MD5 sums checked
** libs

*.o 文件在 /opt/plyr/src 中，来自 github.com/hadley/plyr。它们在我的系统上看起来像这样:

i@scheherezade:/opt/plyr/src$ file *o
loop_apply.o:    LLVM IR bitcode
RcppExports.o:   ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped
split-numeric.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

如果您不知道，-flto 指定链接时间优化，并且已由 R 添加。您是如何设法以这种错误配置的 R 安装结束的？

将-flto 添加到链接命令可能有效吗？或者从 loop_apply 编译行中删除它。如果其中任何一个有效，您需要修复您的 R 安装。
