[转帖]Linux make: g++: Command not found

https://www.cnblogs.com/kerrycode/p/4748606.html

Linux使用make命令时遇到“make: g++: Command not found”，这个主要是没有安装gcc-c++.x86_64，如下所示

[root@localhost nethogs]# make

g++ -g -Wall -Wextra -c packet.cpp

make: g++: Command not found

make: *** [packet.o] Error 127

root@localhost nethogs]# yum search "gcc-c++"
