Emacs needs libjansson when running this #2

Closed andreas-roehler closed 3 years ago

andreas-roehler commented 3 years ago

Thanks for the excellent package. Seems Emacs needs to be configured/compiled with libjansson library, which doesn't exit by default at my Debian/Ubuntu. Got: Debugger entered--Lisp error: (void-function json-parse-buffer)

Maybe mention something like apt install libjansson-doc libjansson4 libjansson-dev (?)

Sure, I should add a check and warning message.

Now, just so I understand how common this is, did you encounter this issue with the Emacs distributed by Debian/Ubuntu, or is it one you built yourself? Are those apt install requirements for building or just running Emacs?

Got the error from a new built from current trunk of 2021.07.27

The Emacs shipped with my Debian 10 is a Emacs 26.1. As it's not even an Emacs27...

Usually use my own builds.

Are those |apt install| requirements for building or just running Emacs?

libjansson seems only needed for the new json-stuff introduced in Emacs27.
