我正在AWS的Linux机器上运行RServer Studio。
我尝试安装ModelMetrics的依赖项caret，并收到此错误:
auc_.cpp:2:10: fatal error: omp.h: No such file or directory
#include <omp.h>
^~~~~~~
compilation terminated.
make: *** [auc_.o] Error 1
ERROR: compilation failed for package ‘ModelMetrics’
这是完整的输出消息

我环顾四周，看起来编译器有错误。我尝试了here列出的解决方案，特别是我运行了这些命令
yum groupinstall 'Development Tools'
mkdir ~/.R
echo "CC=gcc64" >> ~/.R/Makevars
sudo sed -i 's/CC = gcc -m64/CC = gcc64 -m64/g' /usr/lib64/R/etc/Makeconf
即使重新启动RStudio服务器之后，我也会得到相同的输出和错误消息。
看来此错误与problem here非常相似。遵循这些说明后，我仍然没有解决方案，但是我确实找到了我的omp.h文件的位置。
/usr/lib/gcc/x86_64-amazon-linux/4.4.6/include/omp.h
/usr/lib/gcc/x86_64-amazon-linux/4.8.5/include/omp.h
/usr/lib/gcc/x86_64-amazon-linux/6.4.1/include/omp.h
我安装了
Developer Tools并使用这些命令更新了Makeconf文件。sudo sed -i 's/CC = gcc -m64/CC = gcc64 -m64/g' /usr/lib64/R/etc/Makeconf
sudo yum groupinstall 'Development Tools'
然后，我将这些行添加到
Makevars配置文件中。mkdir ~/.R
vi ~/.R/Makevars
CC=gcc
VER=64
CC=gcc$(VER)
CXX=g++$(VER)
CXX11=g++$(VER)
CXX14=g++$(VER)
我重新启动了RStudio服务器，并尝试安装
ModelMetrics并收到此错误，与以前相同。Installing package into ‘/home/User/R/x86_64-pc-linux-gnu-library/3.5’

最佳答案
您已将R配置为在编译C文件时使用gcc64，但是C++文件仍将使用g++而不是g++64进行编译。 ~/.R/Makevars中的以下配置将始终对此进行更改:
VER=64
CC=gcc$(VER)
CXX=g++$(VER)
CXX11=g++$(VER)
CXX14=g++$(VER)
由于上述操作对您不起作用，因此您可能会受到与此用户相同的问题的影响:https://stackoverflow.com/a/49876044/8416610在这种情况下，您可以使用以下命令编辑R的
Makeconf文件sudo sed -i 's/g++/g++64/' $(R RHOME)/etc/Makeconf
(假设您已经将
gcc更改为gcc64)
