Error on startup: "Don't know how to REQUIRE sb-concurrency."

Hi there, thank you for clack.

I know that clackup (the CLI tool) is advertised as the way to start a server, but what if I want to do it myself in a main function in an executable I compiled?

Here is my current main:

(defun main ()
  (format t "Starting server!~%")
  (setf *server* (start-server))
  (handler-case (bt:join-thread (find-if (fn (search "clack" (bt:thread-name %)))
                                         (bt:all-threads)))
    (sb-sys:interactive-interrupt ()
      (progn (format t "Aborting...~%")
             (clack:stop *server*)
             (uiop:quit)))))

As you can see, this is SBCL. But when I compile this and start the server from the command line, I'm told:

Unhandled SB-INT:EXTENSION-FAILURE in thread #<SB-THREAD:THREAD tid=11837 "main thread" RUNNING
                                                {10050081B3}>:
  Don't know how to REQUIRE sb-concurrency.

And it crashes. Do you know what's happening here?

忙しい中ありがとうございます

Thank you for using Clack!

It seems SBCL couldn't load its contrib when it invoked in an executable.

Perhaps it resolves by adding (require 'sb-concurrency) in the main function's file. I'm not sure whether that's the only problem, though.

Thanks! I ended up fixing it by explicitly depending on sb-concurrency in my .asd file.
