Topic:

I need to install the version of GCC(4.6.4) and following the exact command in
the following
https://github.com/jackywei/HOW-TO-BUILD-HHVM-WiKi/wiki/Build-&-Install-GCC4.6.3-in-CentOS-(5.2-&-6.3)
And all steps of installation is successfuly
but when I check the version of gcc that is still old version of 4.4.0
not 4.6.2. Why ?
How can I check what is wrong from my
installation directory at /home/dev/gcc-4.6.3 in which I installed the
package of new version GCc(4.6.3)
And I used gcc -v for version check
Please advise
Duncan

You don't have to uninstall the previous version if you follow the steps above, but if you want to, use the packet management of your OS for that purpose.

Since I have ben installing a lot of version that I don't know how many.

@jkr - I always read the history, I did not see an answer to how many gcc's are present or not that is why I ask this explicitly. The procedure the asker is referring to has instructions to move gcc files to _old etc. I'm referring tho this part:
Do you know for sure how many and what versions of gcc are installed at the asker's system?
And I try
find / -name "gcc*" -print -exec ls -l {} ;
What is command for find / -name "gcc*" -print -exec ls -l {} ; ?
find / -name "gcc*" -print -exec ls -l {} ;
What is command for find / -name "gcc*" -print -exec ls -l {} ; ?

>> Do you have more than one gcc?
Um, that's what all comments before yours were about. Please take the time to read the question history before commenting...

Do you have more than one gcc? Try to find it like this:
find / 2>/dev/null | grep -i gcc
For each line you find, get its version info, for example:
/usr/local/bin/gcc --version
What versions do you get and how many?
find / 2>/dev/null | grep -i gcc
For each line you find, get its version info, for example:
/usr/local/bin/gcc --version
What versions do you get and how many?

BTW, if you can confirm that, you can then set the link to the new version like
'-f' forces overwriting the old link, if you want to be cautious, use '-' instead.

Try
I am pretty sure it will tell you that it is a link to 'gcc-4.4.0/bin/gcc'.
And the 'find' command will do that for all files starting with 'gcc' on your machine.

When I type
which gcc //it shows
/usr/local/bin/gcc
And I try
find / -name "gcc*" -print -exec ls -l {} ;
What is command for find / -name "gcc*" -print -exec ls -l {} ; ?
And then after find command, I check gcc -v
it still show 4.8.0 not 4.6.3
So what I should do next ?

Try 'which gcc' to find out which binary is invoked. Chances are that if you also have 4.4.0 installed, the 'gcc' you call when checking with '-v' is just a link to gcc-4.4.0. You could also try
