I am trying to compile emacs on Ubuntu 12.04. This is because I want to use emacs 24.2. But I am getting this error. How can I fix it?

checking for long file names... yes
checking for X... no
checking for X... true
configure: error: You seem to be running X, but no X development libraries
were found.  You should install the relevant development files for X
and for the toolkit you want, such as Gtk+, Lesstif or Motif.  Also make
sure you have development files for image handling, i.e.
tiff, gif, jpeg, png and xpm.
If you are sure you want Emacs compiled without X window support, pass
to configure.

If you run

sudo apt-get build-dep emacs23

that installs everything that is needed to compile the emacs23 package. Quite likely that's enough to compile Emacs 24.2, too.

Or, in Ubuntu 14: sudo apt-get build-dep emacs24 – nnyby Oct 22 '14 at 15:23

I used to do it this way:

sudo apt-get install build-essential texinfo libx11-dev libxpm-dev libjpeg-dev libpng-dev libgif-dev libtiff-dev libgtk2.0-dev libncurses-dev 

git clone --depth=1 git://
./ # not needed when installing from tarball
make bootstrap
sudo make install

To build docs:

make docs
# or build just the format you want:
make info
make dvi
make html
make pdf

But now I just use the package

sudo add-apt-repository -y ppa:ubuntu-elisp
sudo apt-get update
sudo apt-get install emacs-snapshot
