I just upgraded to emacs 28.2 and my flycheck stopped working. When it loaded it got an error
File mode specification error: (void-function -doto)
I found -doto in elpa/dash, which was installed when flycheck was upgraded. It does not get loaded automatically, and when I load it manually and try using flycheck there is a similar error
while loading: (void-function -compose)
This one I can't find, it does not seem to be anywhere on my system.
The emacs is a new install, packages were all installed with melpa I've reloaded flycheck (version 32) from melpa-stable. -compose is used in a few of the files in lhp-mode, which was also just installed.
Any suggestions?
Solved by Rorschach in a comment, it was a version issue. After deleting an old version of dash.el in my load path it worked.
