Compiling emacs in GNU linux systems
Emacs is available in all GNU-linux distributions. If you want to install emacs directly from any free-software distribution, you may check this information. However, you may be interested in compiling emacs for your operational system.
To compile emacs it's important to install some development libraries before downloading the emacs tarball.
Below there are options to compile emacs in debian-like free software distributions
Install build-essential
sudo apt install build-essential
sudo apt update && sudo apt build-dep emacs
Download emacs (tarball), extract and open the source directory
Visit the Emacs website
Let's say you want to download emacs 28.2. You may use wget to download the
tarball:
wget http://ftp.gnu.org/gnu/emacs/emacs-28.2.tar.gz
Then, extract the files and open a terminal within the main directory of the package.
tar xvfz emacs-28.2.tar.gz
Change the directory to the extracted files:
cd emacs-28.2
Execute the following commands in a terminal to begin with the process
Run the autogen.sh script. The script should be inside the emacs directory.
./autogen.sh
Configure
./configure
Make the package and install in the system
make sudo make install
Facing problems due to lack of XLibs in Debian system
Install the following libraries: (for PureOS or Debian Buster):
libc6-dev libjpeg62-turbo libncurses5-dev libpng-dev libtiff5-dev libgif-dev xaw3dg-dev zlib1g-dev libx11-dev
To install, use:
