A general way to install all dependent libraries when compiling Emacs from its git master source code.

A general way to install all dependent libraries when compiling Emacs from its git master source code.

[Hongyi Zhao]

It's well known that Emacs relies on a number of libraries for its
functionality. On the other hand, different operating systems have
different package/library management tools and even the same library
may have different names when installed on different operating
systems. It would be handy if we had a common way to install all the
dependent libraries when compiling Emacs from its Git Master source.
For this purpose, I've noticed the vcpkg tool [1]. But I'm not sure if
there are some people here have some experiences for using this or the
similar tools to solve this problem mentioned above.

Any hints will be appreciated.

This is unlikely to happen because the libraries Emacs uses are also
used by many other software packages.  So people tend to install them
whenever they have the first package which needs a library, and not
just for Emacs.

What libraries do you mean?

Here is how I get and build it

#! /bin/zsh
#
# this file:
#   http://user.it.uu.se/~embe8573/conf/.zsh/install-emacs
#   https://dataswamp.org/~incal/conf/.zsh/install-emacs

local EMACS_SRC=https://git.savannah.gnu.org/git/emacs.git

emacs-install-prepare () {
    sudo apt-get -qq update
    sudo apt-get install build-essential
    sudo apt-get build-dep emacs
}

emacs-src-reset () {
    git reset --hard
    git clean -xdf
    git pull $EMACS_SRC
}

emacs-src-get () {
    git clone $EMACS_SRC
}

# $ ./autogen.sh
# $ ./configure --with-x-toolkit=no
# $ make
# $ sudo make install

See my following explanation.

Basically, I mean all the libraries installed by the above command,
which will install all dependent libraries for Emacs on the Debian
derivative systems. But when you're not on Debian derivative systems,
you must adapt it to appropriate forms.

dependent libraries = packages in the Debian repos?

For the compilation of Emacs, most of the dependencies are libraries
which are packages named as lib* in Debian apt repository.

Well, you can't install them in a way that works for other
OSs, I guess you could have a script that branches depending
on OS and then executes the OS-specific commands to install
Emacs and Emacs dependencies ...
