Component "swank" not found

[ghost]

I am trying to install cl-sdl2. After i evaluate this line (ql:quickload "sdl2") in a .lisp file i get following errors:

Why is this happening and how can i fix it?

I have installed cl-sdl2 using quicklisp and git: `cd $HOME/quicklisp/local-projects

git clone https://github.com/rpav/cl-autowrap.git

git clone https://github.com/lispgames/cl-sdl2.git`

[rpav]

Erp, the swank stuff should all be behind #+swank .. did you previously load this in emacs with slime?

[ghost]

No. I got the errors as i first time evaluate (ql:quickload "sdl2")

[rpav]

What is in your *FEATURES*? The only way for that to get loaded is if :swank is somehow in *FEATURES*, or if it was previously loaded with swank, and then swank was removed from the system or otherwise became inaccessible. Perhaps something is erroneously setting the feature though.

[ghost]

(print *features*)

:swank is there!

[rpav]

I'm not sure how this could be happening other than stale fasls then; I can quickload a new sdl2 into a bare SBCL with no problems. (Nor is there a swank package after doing so, so it's not getting loaded from what I can tell.)

[rpav]

If you enter something like #+swank (+ 1 1) it returns nothing right?

[ghost]

In a slime session entering it returns this:

CL-USER> #+swank (+ 1 1)

2 Is that what you meant?

[rpav]

Err, wait. You do have :SWANK in *FEATURES*! Apparently I can't forward-search today. That would be a problem, if you don't actually have it loaded or available (at least via ASDF?).

[rogersm]

I have the same issue.

In my case I download and install swank manually during emacs/ccl installation without using quicklisp.

[rpav]

QuickLisp isn't required here per se ... just make sure ASDF can find swank.asd. You could symlink this into ~/.local/share/common-lisp/source or possibly ~/quicklisp/local-projects or something.

[mfiano]

I had the same problem when quickloading outside of SLIME, and clearing fasl's fixed it.

[borodust]

Same problem for me on fresh install (inside SLIME). "Fixed" by quickloading swank directly.

[rogersm]

@rpav take into account some of us don't have swank in asdf/quicklisp as we clone the github repo directly and then point to it in our .emacs file.

That means that when we do 'M-x slime' in emacs the slime elisp starts the lisp image loading swank.lisp correctly, but then is not available via asdf.

Two possible solutions:

a) Changing the dependencies not to have swank as mandatory b) Document this case and ask the user to continue without loading swank.

[rpav]

I'll simply disable the features if swank is not available via ASDF. There's not really another reliable way to depend on it otherwise. Not having swank available via ASDF is essentially erroneous, but apparently people use it this way, so I'll at least make cl-sdl2 check for the situation.

[rpav]

This should now load without ASDF being able to find swank/slynk. Note this does not fix removing swank/slynk after the fact; you will have to remove the fasls and recompile for that.

[rpav]

(Note I also clone sly directly.)

[mfiano]

Fixed.

[ryukinix]

I still can replicate this issue. There is something need to apply the fixed that was mentioned? I'm using Quicklisp and already update the dist for the latest.

[mfiano]

This is most likely due to compiling this outside of SLIME. Try removing your fasl cache and reload from a SLIME or Sly REPL.

[ryukinix]

I fixed doing (ql:quickload 'swank) on SLIME REPL directly, thanks anyway.

[mfiano]

That is an ugly workaround. To be sure I'd need to see your *FEATURES* list in a fresh image, after you have removed your FASL cache.
