Install GCC(4.6.3) on Centos6

Dear Experts,

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

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

find / -name "gcc*" -print -exec ls -l {} \;

Open in new window

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

ls -l /usr/local/bin/gcc

Open in new window

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.

>> 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...

@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:

And I try
find / -name "gcc*" -print -exec ls -l {} \;

What is command for find / -name "gcc*" -print -exec ls -l {} \; ?

Do you know for sure how many and what versions of gcc are installed at the asker's system?
