Sqlite-open Symbol’s function definition is void

GNU Emacs 29.2 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.38, cairo version 1.16.0) of 2024-01-23

Trying to use the sqlite-builtin as the org-roam-database-connector

Installed the emacsql-sqlite-builtin from Melpa

Then tried to set the variable as described in the manual – but i cant make emacs find the function definition sqlite-open :sob:

supposedly org-roam also has a check to see whether the function exists before setting the variable –

any idea what i am doing wrong ?

What did you do exactly?

I installed emacsql-sqlite-builtin from Melpa the version I mentioned

then simply used (setq org-roam-database-connector 'sqlite-builtin)

Just trying to see if the new db connector would speed anything up or not – but it says cannot find the function definition for sqlite-open

eieio-oset: Symbol’s function definition is void: sqlite-open

the default sqlite works – was just interested to check out the new one.

I can see that in the emacsql-sqlite-builtin.el file it says to look for sqlite-open in sqlite library

;;; Code:

(require 'emacsql)
(require 'emacsql-sqlite-common)

(require 'sqlite nil t)
(declare-function sqlite-open "sqlite")
(declare-function sqlite-select "sqlite")
(declare-function sqlite-close "sqlite")

I used '#locate-library to go to the file location …/lisp/sqlite.el

There is nothing that describes the function

(provide 'sqlite)

Strange …

What’s the value after you evaluate this function?

It’s a function in C. I have the same sqlite.el and I can find sqlite-open function.

Did you build your Emacs from source?

When you did, did you have sqlite dev package in your Linux distro (Debian? something like libsqlite3-dev?) – the flag is automatically on. When you do ./configure, the log output would have noted something about sqlite3, like this:

... [my omission]
  Does Emacs use -lwebp?                                  yes
  Does Emacs use -lsqlite3?                               yes
  Does Emacs use cairo?                                   yes
  Does Emacs use -llcms2?                                 yes
  Does Emacs use imagemagick?                             no

Yes, I did compile it from source – thanks for the pointers – I will try and recompile emacs and see if it solves it and collect more data as to what is going wrong, thanks.


Return t if sqlite3 support is available in this instance of Emacs.

Oh and this results in nil

I think something did go wrong during compile time – I have been lazy and copy pasting my entire emacs folder across computers

1. Install the build dependencies for Emacs:

$ sudo apt build-dep emacs
$ sudo apt install libtree-sitter-dev

2. Download and unpack the Emacs archive:

$ wget http://mirrors.nav.ro/gnu/emacs/emacs-29.1.tar.xz
$ tar xvf emacs-29.1.tar.xz

3. Install Emacs in HOME/.local/emacs/:

$ ./autogen.sh
$ ./configure --prefix="$HOME/.local/emacs/" --without-compress-install --with-native-compilation --with-json --with-mailutils --with-tree-sitter CC=gcc-12
$ make -j 4   # Replace the number 4 with the number of cores that your CPU has.
$ make install

These are the install instructions i found somewhere and used…

Thank you so much - recompiling Emacs with the libsqlite3-dev installed from the repo - compiled with sqlite3 enabled and org-roam now defaults to sqlite-builtin.

I needed to install the library in Debian Stable.

You’re the best ))
