本文导语: 求助~~~~~~~~~~~~~~~~~急 1，请问这种情况是不是要下载g++安装包安装,如果是的话要下载哪个版本的g++安装包？用什么命令来安装？ 2.百度说gcc也能编译c++程序，为何会出现error trying to exec ‘cc1plus'（图中第四行）的问题...如何...

1，请问这种情况是不是要下载g++安装包安装,如果是的话要下载哪个版本的g++安装包？用什么命令来安装？
2.百度说gcc也能编译c++程序，为何会出现error trying to exec ‘cc1plus'（图中第四行）的问题...如何解决？
3.还有我是用vmware虚拟机的，可不可以在windows下下载了安装包再放去虚拟机linux里面运行？
问题有点多，新手第一次linux编c++，求指教，感激不尽~~~

Your command is all right.
Unfortunately, you can't install gcc-c++, in fact you can't yum anything. The reason is that you installed a RedHat Enterprise Linux, which is not free. You will have to pay for the subscription(yum). Backup your personal belongings and install a new VM using centOS, which is almost as same as RHEL, but free.
GCC standards for GNU Compiler Collection. When you compile cpp, it will invoke g++. The reason you can't invoke g++ through gcc is probably because the gcc package you installed doesn't contain the support to c++.
There are some subtle differences that you may want to know, for instance, gcc will not link std C++ libraries by default (but g++ will do it).
As for downloading package separately on windows and then install on VM, don't waste your time on a RHEL. Try CentOS, then you will never have to worry about yum update...
