Installing C++ on a CentOS running Linux
 

Hello.

I need to install C++ on a CentOS system that is running linux. or I need to check if it has c++ installed... advice?

Install the g++ compiler. If you do:

That should give you gcc, g++, and the basic include files and libraries you need to compile code.

C++
 

will this also give me c++? or just compiling tools?

I am also install on a HPCC server... does this matter?

Errs
 

[acolombo@hpc-login2 ~]$ yum groupinstall "development tools"
Loaded plugins: fastestmirror, priorities, refresh-packagekit, security
You need to be root to perform this command.

Installing the c++ compiler :

1) $ su <enter-root-password>
2) # yum install gcc-c++

If you also want all the other "Development tools" :
a) $ yum grouplist
.. to check how to spell "Development tools".
I.e. it is not "development tools".
b) # yum groupinstall "Development tools"

c++ is a language, it's not something that can be "installed" (that's like asking how to install html), so you need to clarify your question. The above posts are telling you how to install a c++ compiler so that you can build c++ code, since that's the closest logical interpretation of what you're asking.

So become root.

and type in root's password

Thanks for the spelling correction (I didn't have a Red Hat based box handy to check on). It's really obnoxious how Red Hat and friends use capitalization in the package group names.
