今天需要编译一个项目的时候在装g++都装不上，
[root@master hadoop]# yum install g++ Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile * base: mirrors.yun-idc.com * extras: mirrors.yun-idc.com * updates: mirrors.yun-idc.com Setting up Install Process No package g++ available.
一直提示这个错误，后面参考网上资料用： yum install gcc-c++就可以，如下图
[root@master hadoop]# yum install gcc-c++ Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile * base: mirrors.yun-idc.com * extras: mirrors.yun-idc.com * updates: mirrors.yun-idc.com Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package gcc-c++.x86_64 0:4.4.7-4.el6 will be installed --> Processing Dependency: libstdc++-devel = 4.4.7-4.el6 for package: gcc-c++-4.4.7-4.el6.x86_64 --> Running transaction check ---> Package libstdc++-devel.x86_64 0:4.4.7-4.el6 will be installed --> Finished Dependency Resolution Dependencies Resolved
至于是什么原因就不清楚
