Question

我正在编译需要-lrt库的Makefile。我的编译器是gcc-8，目前正在OSX Mojave OS上工作。我使用make命令从终端运行，并且出现以下错误：

ld：找不到用于-lrt的库 collect2：错误：ld返回1退出状态 make：*** [eflomal] Error 1

我已经尝试从LDFLAGS中删除-lrt，但是在这种情况下，我会遇到其他错误：

/usr/local/Cellar/gcc/8.3.0/bin/gcc-8 -lm -lgomp -fopenmp  eflomal.o   -o eflomal
Undefined symbols for architecture x86_64:

      _main in eflomal.o
      _align in eflomal.o
ld: symbol(s) not found for architecture x86_64

Makefile标头如下：

export CXX=/usr/local/Cellar/gcc/8.3.0/bin/g++-8
export CC=/usr/local/Cellar/gcc/8.3.0/bin/gcc-8
CFLAGS=-Ofast -march=native -Wall --std=gnu99 -Wno-unused-function -g -fopenmp
# This is more suitable for debugging:
#CFLAGS=-Og -Wall --std=gnu99 -Wno-unused-function -g -fopenmp
#LDFLAGS=-lm -lrt -lgomp -fopenmp
LDFLAGS=-lm -lgomp -fopenmp -lrt

使用gcc编译器而不是clang需要前两行（OSX上的默认设置）。

关于如何解决此问题的任何想法？

找不到-lrt的库
