Vterm module must be re-compiled every restart when using straight.el.

[akoen]

Whenever Emacs is restarted, the vterm module must be recompiled:

Once the module is compiled vterm works normally.

Here is the output of the module build:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

Note that straight.el says building vterm during initialization. This occurs every restart.

Any help would be greatly appreciated!

I bet this is related to akhramov/org-wild-notifier.el#21, or rather, the fix is very similar.

It looks like you are using Doom Emacs. When I try to use vterm with Doom Emacs, I don't have this problem. How do you install vterm?

[akoen]

I am using vanilla emacs with the doom modeline. Here is my configuration:

(use-package vterm
  :ensure-system-package (vterm-ctrl . libvterm)
  :commands vterm vterm-mode
  :init
  (setq vterm-kill-buffer-on-exit t)
  :config
  (add-hook 'vterm-mode-hook 'evil-emacs-state)) ;; Evil in terminal is simply wack

That being said, I can reproduce the bug with a blank use-package declaration:

(use-package vterm)

[failable]

Is there a way to customize the location of build directory?
