Hi,

I have followed your guide and successfully installed gcc-9.1.0,
and running which gcc –version returns gcc (GCC) 9.1.0.

However, I now have 2 gcc in my machine and compiling c++ file outputs this error:
./test_output2: /lib64/libstdc++.so.6: version `GLIBCXX_3.4..21′ not found (required by ./test_output2)

I have checked that indeed GLIBCXX_3.4.21 is not found using:
strings /usr/lib64/libstdc++.so.6 | grep GLIBCXX_3.4.21

However, I see that is GLIBCXX_3.4.21 is found using:
strings /usr/local/lib64/libstdc++.so.6 | grep GLIBCXX_3.4.21

Running where gcc returns:
/usr/local/bin/gcc
/usr/bin/gcc

Running which gcc returns:
/usr/local/bin/gcc

I found a solution that using LD_LIBRARY_PATH may resolve this, however Im afraid its not the best practice so I wonder if there is another way to do this like specifying the linker or rpath for gcc and g++

In reply to Andrei. you can find the ip address on your vps, dedicated server, cpanel or other server control panel. and port usually is 22

In reply to Thomas. You can try running the command "autoreconf -i" before running this command.

Hi,I have an error in configuring the downloaded package:
Once the prerequisites are downloaded execute the following command to start configuring the GCC build environment

./configure –disable-multilib –enable-languages=c,c++

result: configure: error: cannot find install-sh, install.sh, or shtool in “.” “./..” “./../..”

Any thoughts?

Hi, I want to install ORACLE 19c on centos 7.
While going through installation stages oracle wants gcc 4.8.2 to be installed.
when I type “yum install gcc” as you know it install gcc 4.8.5.
How can i install older versions? Thanks.

In reply to John Mulhere. Please make sure to remove the old version, then install it from scratch.

By: John Mulhere

John Mulhere — Fri, 14 Oct 2022 13:54:09 +0000

I followed these instructions and installed gcc 12.2.0 on CentOS 7.9. The make and make install steps completed, but when I run gcc –version I still see 4.8.5. The new gcc looks like it installed successfully to /usr/local/lib, but it’s doesn’t look like it actually replaced the older version.

In reply to Ram. We are not sure what the user is saying but if you want to have the latest version you can download the source manually just refer to step 3 on how to install it manually.

By: Ram

Ram — Tue, 23 Aug 2022 02:55:16 +0000

Hi Admin

I followed the steps but when I check the version I got 4.8.5 instead of newer version.

One of the user mentioned that we need to reload the files before Step-4. could you please provide the instructions on reloading the files ?

Thank you

Aarón López — Thu, 02 Jun 2022 12:27:33 +0000

Hi thanks for this information,
I have updated but when check the version with gcc –version I got 4.8.5 instead of 7.5
I know 7.5 is installed in /usr/local/lib/../lib64
But I am missing something.
Thank you.

By: admin

admin — Sat, 28 May 2022 06:23:11 +0000

In reply to Aven. Hi, Please make sure that the desired version of gcc is downloaded from the link in step 3.

By: Aven

Aven — Fri, 27 May 2022 07:32:11 +0000

Thanks for your sharing.
However, in my case, the gcc –version remains 4.8.5 after installation while g++ has been successfully upgraded to 11.2. Is there a way to change default gcc version?

Thanks,
Aven

In reply to Taofeek. You need to install the GNU C++ compiler. For Centos "yum install gcc-c++".

By: Taofeek

Taofeek — Thu, 22 Jul 2021 19:01:33 +0000

Im new to linux. I installed the gcc compiler to compile openmpi on google cloud and it seemed to install fine since I checked using gcc –version. But when I tried to compile openmpi using ./configure –prefix=”/home/bogunbayo/openmpi411/” it gave the following error messages

In reply to Sanjay. It is highly recommended to start a screen session because the installation would take a while to accomplish and losing your connection or any interruption might break the installation and you have to start again.

By: admin

In reply to TOD. Please check /usr/local as that is the default location of the installation. Please make sure you have downloaded the prerequisites and configured the GCC build environment as stated on the procedure.

In reply to Rahul. What do you mean by reload files from path again? I followed the steps but I still see the old version on using the gcc --version command. Maybe this is the step that I am required to do.

By: yaodav

yaodav — Mon, 08 Jul 2019 06:20:08 +0000

i installed the gcc and g++ according to the guide but when i do g++ –version it give me :
yaodav@localhost ~]$ g++ –version
g++ (GCC) 7.4.0
but when i give the command as sudo i get :
yaodavdav@localhost ~]$ sudo g++ –version
g++ (GCC) 4.8.5 20150625 (Red Hat 4.8.5-36)
how to enable the new gcc also to the sudo?

Not true, you can build it locally without having root or sudo access just fine.
You can use:

./configure –prefix=/home/user/your/repo
make PREFIX=/home/user/your/repo install

Just an extremely minor thing. Before point 4, you might consider advising the user to reload files from the path again. Otherwise older version of gcc appears on invocation at that step.

In reply to MikeT. The latest gcc and g++ version distributed by CentOS 7 is 4.8.5. If you would like to install a different version you would have to install it from source.

By: MikeT

MikeT — Sat, 22 Dec 2018 18:20:21 +0000

I followed your steps, and things seemed to go as expected, except there is a discrepancy between the version reported by gcc –version, which is 5.5.0 (the release I need for my client) and g++ -v, which reports 4.8.5. How do I make it so g++ links to the same compiler installation?

In reply to Andrei.

This command is used to establish an SSH connection to a remote server. If you are doing this installation on your local computer, you can skip this part.

The IP address is a unique numerical number assigned to every device connected to the Internet. The Port_number in this command refers to the port number of the SSH service which is running on your server. Usually, the default SSH port is set to 22.

If you are not sure about the IP address and the SSH port number of your server you should contact your hosting provider and ask them for this information.

By: Andrei

Andrei — Wed, 11 Jul 2018 21:18:28 +0000

Hi,
I’m new to linux and i’m trying to understand it better, can you please detail this line: “ssh root@IP_Address -p Port_number
”
What is IP_address, where do i find it, and what is Port_number and where do i find it, if you could provide an answer it would be awesome.

Thanks in advance!
