iam not an expert in linux as you can see
if someone can explain me the whole process that i need to do it will be great
thanks again

well FIRST off
Mandriva
is not redhat
it is not compatible
and you are trying to install a glib for a ARM cup and for a different OS

think of it as trying to install apple MAC "system files"
on windows 8
-- will not work

RHEL6 is a commercial product .
One that you NEED to BUY $$$ the REQUIRED support contract


please post the full output of this
including any errors

hi,
thank you very much for your help
i know that REDHAT cost $$ but for now i need it as a test machine for the production env.


[root@localhost ~]# yum repolist all
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
repo id repo name status
rhel-source Red Hat Enterprise Linux 6Server - x86_64 - Source disabled
rhel-source-beta Red Hat Enterprise Linux 6Server Beta - x86_64 - Source disabled
repolist: 0

here is your problem
register it with redhat

that really is the only way to install gcc 4.7

PS
gcc 4.4.7 should be the default and already installed
do you just need gcc
or
MUST IT BE 4.7

4.4 is the DEFAULT compiler

if all you need is a compiler
then the normal command will WORK once you register the install
and gcc and EVERYTHING it needs will be installed
there are a LOT of other programs that gcc NEEDS

our client said he wants only 4.7 gcc and nothing else.
maybe ill try to install it on centos?
want is the the right way to do this on cent os?

← #10 .

Simple :

If you have a 64bits OS, el6, change line 3 in
/etc/yum.repos.d/devtools-1.1.repo to :
baseurl=http://people.centos.org/tru/devtools-1.1/6/x86_64/RPMS/

Install gcc-4.7.2 : $ cd /usr/bin/
# ln -s /opt/centos/devtoolset-1.1/root/usr/bin/g++ g++47
# ln -s /opt/centos/devtoolset-1.1/root/usr/bin/gcc gcc47

Then you have /usr/bin/{ gcc47, g++47 }.
Test compilation : $ export CC=gcc47 CXX=g++47 && <other-command>.
* No issues with a complicated piece of software :
Hundreds of files c and c++ code were built OK with gcc47, g++47.

i dont have this path:
"/etc/yum.repos.d/devtools-1.1.repo"

this is the out put from my machine:

I guess you mean that you don't have the file ?

Please read post #3 by @neil117 :
The first link is the file "/etc/yum.repos.d/devtools-1.1.repo"
