How do I install g++ for Fedora?

Question

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

You probably need to install a package perhaps named `g++-4.7` (or `g++-4.6`). — Basile Starynkevitch, Oct 18 '12 at 10:50

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

I got this error during the install: https://bugzilla.redhat.com/show_bug.cgi?id=494006. Running `yum clean metadata` resolved the error and I was able to install gcc-c++. – yellavon May 05 '14 at 18:35

It's worth noting that this is discoverable by doing `sudo yum install /usr/bin/g++` (or `sudo yum install /usr/bin/g++`). – mattdm Apr 06 '16 at 22:57

Alternately, without having to know exactly where the binary ends up, you can do `yum whatprovides '*bin/g++'` or even `yum whatprovides '*/g++'`. – asciiphil May 06 '16 at 14:15

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

sudo dnf install gcc-c++

I have already installed gcc. I have been compiling `c` using the same – saplingPro Oct 18 '12 at 10:53

g++ is like an aditional for gcc, so if you want g++ the package you need is gcc-c++, try it... – Hola Soy Edu Feliz Navidad Oct 18 '12 at 10:56

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.

Update is not required. This is where fedora differs from debian – xiamx Aug 23 '15 at 00:49

`update` will update the current software, though. (like `upgrade` under Debian) It could be useful. – Alexis Wilke Feb 24 '17 at 22:18

It's always a good idea to update the current software before adding new packages. It's not necessary, but you can get into some weird situations (particularly around multiarch) if you don't. – mattdm Oct 31 '17 at 12:07

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.

In the newer distribution you can just type command as blow

su root
dnf update
dnf install gcc-c++

Unfortunately, the `gcc-g++` package does not exist. – Motine Mar 10 '16 at 18:13
Again, note `c++` not `g++` in the package name. – mattdm Oct 31 '16 at 11:15
As of now (2020-04-20) both ```dnf install g++``` and ```dnf install gcc-g++``` resolve to ```gcc-c++``` (and tell me it's already installed :)). [for the sake of future visitors] – Will Crawford Apr 19 '20 at 23:38

this worked for me on Fedora 36:

sudo dnf groupinstall c-development

It will install the cc (gcc) and c++ (g++):

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.
