How would you do it? Get Emacs to install and compile pdf tools from the source, or just to call the package manager from the distribution/OS of choice, which I sure are as many as users here.

I am defenetly more happy installing applications through package manager from my distribution then through Emacs. Mostly because of updates and dependencies with other applications. Will Emacs also track when those tools are updated, bugs fixed etc?

Unless you would to turn Emacs into OS package manager a lá pacman, rpm, etc, which I wouldn't mind by the way, but I don't think Emacs is there.

Also pdf-tools are used by other applications in system so it is
easy to get them in any distro, inclusive proprietary OS:s(Win,
Mac). Why shoujld pdf-tools be different then any other tool we use in
Emacs (binutils, compilers, debuggers, grep, ag, you-name-it)?

I'm not quite sure I follow. We're talking about the Emacs package pdf-tools, which isn't used by other applications, because, well, it's an Emacs package. :-) The pdf-tools package uses a C program called epdfinfo to actually read the pdf and feed Emacs all the info it needs to display the pdf file. Epdfinfo is part of the pdf-tools package and needs to be compiled before you can use the package in Emacs.

Epdfinfo uses Poppler and in order for it to be built, a number of development requirements need to be installed. pdf-tools will try to install these through the system package manager, but this, too, can be done manually if you prefer.

So Emacs is not being made into a package manager for .deb or .rpm files, the only thing that needs to be compiled is a C program that comes with the package.
