make报错 - unrecognized command line option “-std=c++14

cmake ..成功,但make报错:

unrecognized command line option “-std=c++14

尝试的解决方案:

1.将GCC/G++升级到了8.4  依然报错

2.除了将/gcc-8.4.0/bin/gcc,/gcc-8.4.0/bin/g++这两个命令做了软连接到/usr/bin和/usr/local/bin这两个目录外,还将c++,cpp这两个命令也做了软连接

但依然报错

3.在cmake ..中间,添加DCMAKE_CXX_COMPILER参数,问题解决.

cmake -DCMAKE_CXX_COMPILER=/usr/local/bin/g++ ..
