How to install libg2c.so.0 on Ubuntu 18.04 64bit

I'm using:

Linux ip-172-31-28-209 5.4.0-1059-aws #62~18.04.1-Ubuntu SMP Fri Oct 22 21:51:38 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

I encounter an error while running a program:

while loading shared libraries: libg2c.so.0: wrong ELF class: ELFCLASS32

How can I resolve it?

I looked at this post, but it's for 32bit version of Ubuntu.


Solution 1:

Even after 13 years this 64-bit library can be installed by direct download using commands below:

cd ~/Downloads
wget -c https://old-releases.ubuntu.com/ubuntu/pool/universe/g/gcc-3.4/gcc-3.4-base_3.4.6-6ubuntu3_amd64.deb
wget -c https://old-releases.ubuntu.com/ubuntu/pool/universe/g/gcc-3.4/libg2c0_3.4.6-6ubuntu3_amd64.deb
sudo apt-get install ./gcc-3.4-base_3.4.6-6ubuntu3_amd64.deb ./libg2c0_3.4.6-6ubuntu3_amd64.deb
