    Most users don't install from source. What are you trying to do here? There may be an easier way to install what you are after. If not you will need to install the dependences first. sudo apt-get install build-essential libncurses5 zlib1g gawk flex then see what other errors you get.

It fails because of missing dependencies. You need to install the following packages:

sudo apt-get install gawk zlib1g libncurses5 g++ flex

After installing these packages your command should run through.

    OP will need the development packages of those libraries zlib1g-dev and libncurses5-dev.

Making menuconfig is requiring You to have developer's libraries of some packets that are used by a build You want to perform.

There is one of answers: How do I install ncurses header files?

Yeah, You can be not in need of ncurses binaries, but You do need it's developer's libraries. Something alike is about the rest of dependencies.

On kubuntu 16.04LTS I had a similar issue compiling openwrt, but no package existed that satisfied the specific issue with ncurses:

Build dependency: Please install ncurses. (Missing libncurses.so or ncurses.h)

The only way to fix it was to add the following repository to my sources:

sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe"
sudo apt-get update
sudo apt-get install libncurses5-dev

On kubuntu 16.04LTS the answer from @MoonCactus have fixed ncurses problem, It's great.

but for 

Build dependency: Please install ncurses. (Missing libncurses.so or ncurses.h)

you can try 

aptitude install zlib1g-dev

     Keep the following packages at their current version:
1)     zlib1g-dev [Not Installed]

  • It seems you've got a copy-paste problem, you are talking about ncurses and installing a zlib package
