train_logReg_param.o:train_logReg_param.cc:(.text+0x3407): more undefined references to `std::__thro

001、make 编译 报错：train_logReg_param.o:train_logReg_param.cc:(.text+0x3407): more undefined references to `std::__throw_out_of_range_fmt(char const*, ...)' follow

002、解决方法（可能是gcc 版本的问题）

a、gcc当前版本：

(py38) [root@pc1 Augustus-3.5.0]# gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

b、升级gcc版本至11，升级后版本： gcc升级过程：https://www.cnblogs.com/liujiaxin2018/p/17808659.html

(base) [root@pc1 Augustus-3.5.0]# gcc --version
gcc (GCC) 11.2.1 20220127 (Red Hat 11.2.1-9)

003、编译测试

(base) [root@pc1 Augustus-3.5.0]# make    ## 再次编译测试，果然之前的报错消失，证明了前边的报错就是gcc版本的问题造成的。
