Install ruby from source in Ubuntu7.10

Yesterday I installed Ubuntu 7.10 on my machine and set up the ROR platform. As I am a new Linux user, I have made many detours in compiling and installing ruby from source, so I will write it down for future use.

Because the gcc after Ubuntu 7.10 is installed by default cannot compile c source, to compile ruby from source, you must first install build-essential.

Run the following command to install the SDK from the source:
Sudo apt-get install build-essential

Tar xvf ruby-1.8.6-p110.tar.bz2

Enter the ruby-1.8.6-p110 directory after decompression:
Cd ruby-1.8.6-p110

Sudo./configure -- prefix =/opt/ruby -- enable-install-doc

Make & install:

Sudo make
Sudo make install
