loop_apply.o：无法识别文件：无法识别文件格式

Question

我正在尝试安装R的plyr程序包。以下是错误消息：

* installing *source* package ‘plyr’ ... 
** package ‘plyr’ successfully unpacked and MD5 sums checked 
** libs 
clang++ -I/opt/R-3.4.1/include -DNDEBUG -I"/home/isomorphismes/R/i686-pc-linux-gnu-library/3.4/Rcpp/include" -I/usr/local/include -fpic -I/opt/boost_1_61_0/boost -c RcppExports.cpp -o RcppExports.o

* removing ‘/home/cd/R/i686-pc-linux-gnu-library/3.4/plyr’ 

的*.o文件在/opt/plyr/src，从github.com/hadley/plyr。他们看起来像这样我的系统上：

[email protected]:/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

在你不知道的情况下，-flto指定链接时优化，并已被R.加你是怎么解决这样的配置错误落得R安装？

添加-flto链接命令可能工作？或者从loop_apply编译行中删除它。如果其中任何一项工作，您需要修复您的R安装。
