Thank you very much indeed gnohz!
I spent hours without success in the configuration until I came across your post. I configured org-roam totally manually with use-package instead of creating a private layer, but org-roam was mysteriously not loaded until I added this line of code:
I did not know that Spacemacs’ org layer includes the org-roam package, so we need to exclude it from org layer; maybe you discovered this by digging into the source code.
Also the suggested configuration for org-roam in the official Spacemacs documentation (4.16. Org-roam support ) was a disaster for me, I was even unable to run emacs in daemon mode. By the way, by configuring org-roam manually with use-package, everything is working fine so far.
For the benefit of other users, I share my .spacemacs conf, with org-roam-ui also already configured and working:
(defun dotspacemacs/layers ()
"Layer configuration:
This function should only modify configuration layer settings."
(setq-default
(org :packages (not org-roam))
)
dotspacemacs-additional-packages '(
(org-roam)
( simple-httpd )
( websocket )
(org-roam-ui :location (recipe :fetcher github :repo "org-roam/org-roam-ui" :branch "main" :files ("*.el" "out")))
)
))
(defun dotspacemacs/user-config ()
(require 'org)
(setq org-enable-roam-support t)
(use-package org-roam
:after org
:ensure t
:init (setq org-roam-v2-ack t) ;; Acknowledge V2 upgrade
:custom

(org-roam-completion-everywhere t)
:config

("C-c n t" . org-roam-tag-add)
("C-c n a" . org-roam-alias-add)

PS: do not forget to check that you have the path to gcc.exe and git.exe in your emacs exe-path variable.
