How do I install g++ for Fedora?

问题:

How do I install g++ for Fedora Linux? I have been searching the dnf command to install g++ but didn't find anything.

How do I install it?

I have already installed gcc

回答1:

The package you're looking for is confusingly named gcc-c++.

回答2:

instead of g++ you have to write gcc-c++

sudo dnf install gcc-c++

回答3:

You should exec:

dnf install gcc-c++

回答4:

I had the same problem. At least I could solve it with this:

sudo yum install gcc gcc-c++

Hope it solves your problem too.

回答5:

try sudo dnf update and then sudo dnf install gcc-c++

回答6:

Since Fedora 22 yum has been deprecated so the commands given in other answers will actually fire up 'Dandified yum' i.e. dnf. So the new command to install g++ in recent distributions is

su -c "dnf install gcc-c++"

As of Nov 2015 this installs the 5.1.1 version.
Also note that in Fedora 23 when I gave the command g++ -v, Fedora automatically asked me if I want to install gcc-c++ package. I think thats nice.(After the install it also ran the command g++ -v for me)
Only nit pick that I can do about it is that instead of a progress indicator you just get * Downloading packages... message which you may not like if you are on a slow internet connection.

Run the command bellow in a terminal emulator:

sudo dnf install gcc-c++

Enter password and that's it...

回答8:

Just make a sample 'Hello World' Program and try to compile it using "g++ sam.cpp" in terminal, and it will ask you if you wish to download the g++ package. Press y to install.

In the newer distribution you can just type command as blow

su root
dnf update
dnf install gcc-c++
