【问题描述】：
我在 AWS 上的 Linux 机器上运行 RServer Studio。
我尝试安装 ModelMetrics，这是 caret 的依赖项，但收到此错误：
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，似乎编译器有错误。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
即使在重新启动 RStudio Server 后，我也会得到相同的输出和错误消息。
看起来此错误与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)
我重启了RStudio Server，尝试安装ModelMetrics，还是收到了这个错误，和之前一样。

【问题讨论】：
-
你的 gcc --version 是什么？
-
我启动了一台全新的linux机器，得到
gcc (GCC) 7.2.1 20170915 (Red Hat 7.2.1-2) -
请注意，您找到的
omp.h文件都不是 gcc 7.2.1 版。 -
新的错误日志显示仍然使用
g++而不是g++64。R CMD config CXX的输出是什么？ -
输出是g++64
