gcc ++

jpt624 · 07-23-2010, 05:20 PM

hi
I just loaded rhel5.I have a tool that needs g++
and its not loaded
I know enough to be dangerous...I know what Yum is.
I do--
yum install gcc-c++
and get
No package gcc-c++ available.
Nothing to do
this is where I'm lost..
I suspect I'm not pointing to the correct repo
I dont have a separate file for repos
thanks for the wisdom............

my yum.config is:
[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
metadata_expire=1800

[rhel5]
name = rhel5

baseurl=http://dag.linux.iastate.edu/dag/redhat/el5/en/i386/dag

g++ is just a part of gcc. install all of gcc

1) su , 2) yum install gcc-c++

And if "No package gcc-c++ available" appears,
please check, that your Redhat account is activated.
( No Redhat account : yum will not work.)

The repo URLs you show, will only provide some extra packages.
Also : epel etc. will only work with the presence of the original "[redhat.repo]".

yum upgrade seems to work--- so yum appears to be working but I still
get:

[root@localhost Downloads]# yum install gcc-c++

Nothing to do

Please don't double post. Just edit the original one if you want to modify it.

Maybe you can try:

Code:

yum search gcc c++

?

I don't know if it will help, I'm not very familiar wit yum.

GCC C++ uses the command g++ so if you want to see if you already have it installed, use the command

Code:

which g++

If you want to see what package it is in, I'm not certain about RHEL, but in Centos it would be: switch to root and do

Code:

yum provides "*/g++"

Hi.

Using:

Code:

yum info '*gcc*'

yields (among many other items):

Code:

Name       : gcc-c++
Arch       : i386
Version    : 4.1.2
Release    : 48.el5
Size       : 6.5 M
Repo       : installed
Summary    : C++ support for GCC
URL        : http://gcc.gnu.org
License    : GPL
Description: This package adds C++ support to the GNU Compiler Collection.
           : It includes support for most of the current C++ specification,
           : including templates and exception handling.

Looking at the repositories for this installation:

Code:

$ yum repolist
Loaded plugins: priorities
repo id                     repo name                              status
addons                      CentOS-5 - Addons                      enabled:    0
base                        CentOS-5 - Base                        enabled: 2599
extras                      CentOS-5 - Extras                      enabled:  333
updates                     CentOS-5 - Updates                     enabled:  352
repolist: 3284

This machine runs CentOS:

Code:

OS, ker|rel, machine: Linux, 2.6.18-194.3.1.el5, i686
Distribution        : CentOS release 5.5 (Final)
gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-48)
g++ (GCC) 4.1.2 20080704 (Red Hat 4.1.2-48)

Running the suggestion from johnsfine (root not needed):

Code:

$ yum provides "*/g++"
Loaded plugins: priorities
base/filelists_db                                        | 3.4 MB     00:12

updates/filelists_db                                     | 1.3 MB     00:04     
gcc-c++-4.1.2-48.el5.i386 : C++ support for GCC
Repo        : base
Matched from:

gcc-c++-4.1.2-48.el5.i386 : C++ support for GCC
