Compiling GNU Nano

Brief tutorial on compiling software.

Prep

First, start your Fedora VM machine in VirtualBox, update it, and then power it off. To update, use dnf:

$ sudo dnf check-update ; sudo dnf update

And then poweroff:

$ sudo poweroff

Once it's powered off, use VirtualBox to clone it. After the clone is created, start the clone. Once you have a command line, install the C development tools:

$ sudo dnf groupinstall 'C Development Tools and Libraries'

Download the Source

We will need to download the source code to both nano and ncurses. We'll do that with wget.

First, create a src directory in your home directory and change to it:

$ cd ; mkdir src ; cd src

Download the most recent, stable versions of nano and ncurses:

$ wget https://www.nano-editor.org/dist/v3/nano-3.0.tar.xz
$ wget https://ftp.gnu.org/gnu/ncurses/ncurses-6.1.tar.gz

STOP HERE. We'll discuss and do the rest in class

Extract the Source

Use tar to extract the tarballs:

$ tar xf nano-3.0.tar.xz
$ tar xf ncurses-6.1.tar.gz

Read the READMEs

Change to each of the new directories and read the README files.

Compiling from Source

Configure, Make, Make Install

First change to the ncurses directory:

$ cd ncurses-6.1

And then configure, make, and make install:

$ ./configure
$ make
$ sudo make install

If successful, then change to the nano directory, and repeat the above:

$ cd ../nano-3.0
$ ./configure
$ make
$ sudo make install

Since nano was already installed on your system, you now have two versions. The compiled version is installed in /usr/local/bin/. Compare:

$ which nano    # to see which is the default
$ whereis nano  # to see where nano exists on the system
$ # compare binaries
$ /usr/bin/nano --version
$ /usr/local/bin/nano --version

Let's update our $PATH variable to remove the old version. Make sure that you're in your home directory, and then:

$ nano .bash_profile

In the text editor, append the following text with the pathname /usr/local/bin/:

This:

PATH=$PATH:$HOME/.local/bin:$HOME/bin

Becomes this:

PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/bin/

Save and exit from nano and then source the file. Sourcing the file makes bash aware that the $PATH variable has been changed:

$ source .bash_profile
$ which nano

Now, we can remove the older version of nano:

$ dnf list installed nano
$ sudo dnf remove nano

Note: ./configure --help to get a list of possible options.
