I'm seeing an odd behaviour when loading shared libraries under slime/swank. From a command line REPL:
* (asdf:load-system :cffi)
T
* (cffi:load-foreign-library "s:/src/lla/lib/libopenblas-0.3.21.dll")
#<CFFI:FOREIGN-LIBRARY LIBOPENBLAS-0.3.21.DLL-518 "libopenblas-0.3.21.dll">
all good.
The same from emacs/slime/swank just hangs. The workaround is to go to the *inferior-lisp* buffer and press enter. After doing that the load unhangs and things proceed normally.
Any ideas? I'll report this to the slime folks if it turns out to be a bug, and it looks like it to me, but before I do thought I'd check here first to see. This is on MS Windows, if that has anything to do with it.

While using SBCL normally I want to try CCL for some testing and installed it via homebrew on my computer. That worked fine but I fail to use quicklisp with CCL. If I try to load quicklisp's setup.lisp I get the following error message:
➜ ~ ccl64

I couldn't find a simple solution searching the web. CCL comes with ASDF as (require 'ASDF) is working. In quicklisp's documentation I couldn't find anything about extra efforts to use it with two lisp implementations in parallel.
If I check ASDF's version as suggested here I get "3.1.5" as installed version, which should be quite recent.
Is there anything obvious I am missing?
I think I found it: I had some old data in my ~/.cache directory from another attempt to install ccl. After deleting it, I can load quicklisp's setup.lisp without any error.
Please advice If I should delete my question or leave it here to prevent others from repeating my errors.
Please note that various Lisps have some startup files. Some of them are by default:
SBCL: ~/.sbclrc
CLISP: ~/.clisprc.lisp
Clozure: ~/.ccl-init.lisp
From the documentation of CCL:
By default, Clozure CL will look for a file named ccl-init.lisp in your home directory, and load it upon startup. On Unix systems, it will also look for .ccl-init.lisp.
CCL uses an ordinary lisp file called ccl-init.lisp which on unix systems is usually put on your home path. So you can add the following lines in that file (on my Ubuntu machine it's path is /home/me/.ccl-init.lisp) which instructs CCL to load quicklisp upon startup:
#-quicklisp
(let ((quicklisp-init (merge-pathnames "quicklisp/setup.lisp"
(user-homedir-pathname))))
(when (probe-file quicklisp-init)
(load quicklisp-init)))
This is enough for enabling your CCL to communicate with quicklisp.
Anything that Atom + proto-repl does involves lein, so I decided to check out lein. 'lein help' works, but attempting 'lein repl' gives the following errors:
gw-mac-pro:~ gr$ lein repl
Could not find artifact proto-repl:proto-repl:jar:1.4.24 in central (https://repo1.maven.org/maven2/)
Could not find artifact proto-repl:proto-repl:jar:1.4.24 in clojars (https://repo.clojars.org/)
This could be due to a typo in :dependencies, file system permissions, or network issues.
If you are behind a proxy, try setting the 'http_proxy' environment variable.
Could not resolve dependencies
I get the same set of messages when I attempt to run code from within Atom.
I've searched for hours for any kind of arcana about Atom, lein, or proto-repl, and I'm amazed that searching on 'lein error could not find artifact' continues to find nothing useful.
I'm surprised that no one has encountered this same problem. I'm running on macOS Mojave (10.14.6). Can you help me? Thanks.
Up to now in my Lisp adventures I've just been pasting functions as written in a code editor into the REPL to run them, but I now have a program of sufficient size to build on that it will be convenient to use (load "filename.lisp") for the first time in my workflow.
Must I start using packages and/or namespacing to achieve this?
I find that when I use load, as above, I get
** - Continuable Error
DEFUN/DEFMACRO(CLASS): #<PACKAGE CLOS> is locked
If you continue (by typing 'continue'): Ignore the lock and proceed
The following restarts are also available:
SKIP :R1 skip (DEFMACRO CLASS # ...)
RETRY :R2 retry (DEFMACRO CLASS # ...)
STOP :R3 stop loading file /Users/m/cl/ansi-cl/ch17-objects/177d-new-full.lisp
ABORT :R4 Abort main loop
My .lisp file contains a macro called class, so I understand the error, sort of.
The thing is, when I paste the contents of the file directly into the REPL, I get no such error.
What's causing the difference in behaviour?
Is it packages, namespaces or something else?
I can indeed just type continue, and the file will load, but I'd like to understand what is happening here; what's the cause of this "Continuable error", and how should I deal with it if at all?
Package locking in CLISP is explained in the manual.
Symbol class is an ANSI CL symbol, so it cannot name any user-defined entity, and thus your program is not conforming, as explained in 11.1.2.1.2 Constraints on the COMMON-LISP Package for Conforming Programs.
You should rename your macro.
The lack of the error in the REPL is a bug in homebrew clisp.
CLISP as distributed with ubuntu works correctly.
When I build CLISP from sources on Mac, it works correctly too.
If I want to create a Lisp-image of my program, how do I do it properly? Are there any prerequisites? And doesn't it play nicely with QUICKLISP?
Right now, if I start SBCL (with just QUICKLISP pre-loaded) and save the image:
(save-lisp-and-die "core")
And then try to start SBCL again with this image
sbcl --core core
And then try to do:
(ql:quickload :cl-yaclyaml)
I get the following:
To load "cl-yaclyaml":
Load 1 ASDF system:
cl-yaclyaml

4: [ABORT ] Give up on "cl-yaclyaml"
5: Exit debugger, returning to top level.
(SB-IMPL::REQUIRE-ERROR "Don't know how to ~S ~A." REQUIRE "sb-sprof")
0]
Alternatively, if I try:
(require 'sb-sprof)
when sbcl is started with saved core, I get the same error. If sbcl is started just as sbcl there is no error reported.
In fact, pre-loading QUICKLISP is not a problem: the same problem happens if sbcl is called initially with sbcl --no-userinit --no-sysinit.
Am I doing it wrong?
PS. If I use roswell, ros -L sbcl-bin -m core run somehow doesn't pick up the image (tested by declaring variable *A* before saving and not seeing it once restarted).
PS2. So far what it looks like is that sbcl does not provide extension modules (SB-SPROF, SB-POSIX, etc.) unless they are explicitly required prior saving the image.
Thanks for the help from #jkiiski here is the full explanation and solution:
SBCL uses extra modules (SB-SPROF, SB-POSIX and others) that are not always loaded into the image. These module reside in contrib directory located either where SBCL_HOME environment variable pointing (if it is set) or where the image resides (for example, in /usr/local/lib/sbcl/).
When an image is saved in another location and if SBCL_HOME is not set, SBCL won't be able to find contrib, hence the errors that I saw.
Setting SBCL_HOME to point to contrib location (or copying contrib to image location or new image to contrib location) solves the problem.
Finally, about roswell: roswell parameter -m searches for images in a specific location. For SBCL (sbcl-bin) it would be something like ~/.roswell/impls/x86-64/linux/sbcl-bin/1.3.7/dump/. Secondly, the image name for SBCL must have the form <name>.core. And to start it, use: ros -m <name> -L sbcl-bin run. (Quick edit: better use ros dump for saving images using roswell as it was pointed out to me)
If you want to create executables, you could try the following:
(sb-ext:save-lisp-and-die
"core"
:compression t
;; this is the main function:
:toplevel (lambda ()
(print "hell world")
0)
:executable t)
With this you should be able to call QUICKLOAD as you wish. Maybe you want to checkout my extension to CL-PROJECT for creating executables: https://github.com/ritschmaster/cl-project
I've been installing lispbuilder-sdl family with quicklisp and encountered error in sdl-gfx:
CL-USER> (ql:quickload "lispbuilder-sdl-gfx")

I use slime+emacs+SBCL under macosx 10.6. I've installed SDL.framework from this link:
http://thirdcog.eu/apps/frameworks#glew
a file called sdl_with_friends.zip and put things under /Library/Frameworks. However it still complains about cannot find framework.
Any idea on this?
The easiest way to install lispbuilder-sdl on Mac OSX is to fire up SBCL and use Quicklisp:
(ql:quickload "lispbuilder-sdl")
It will probably fail, but you can then compile the OS-X specific helper library located in "~quicklisp/dists/quicklisp/software/lispbuilder-20110619-svn/lispbuilder-sdl/cocoahelper"; just cd to this directory and type "make"
To verify that worked, try this:
(ql:quickload "lispbuilder-sdl-examples")
(lispbuilder-sdl-examples:bezier)
Another common gotcha is when you are using Emacs / SLIME. The cocoa bits must run on the primary thread, so you have to invoke things like this:
#+darwin #+sb-thread
(let ((thread (first (last (sb-thread:list-all-threads)))))
(sb-thread:interrupt-thread thread #'(lambda () (ql:quickload "lispbuilder-sdl-examples")))
(sb-thread:interrupt-thread thread #'(lambda () (lispbuilder-sdl-examples:bezier))))
The error is complaining that it can't load the dynamic library for SDL. I'm sorry - I don't know much about the directory layout on macs (which appears to be where you're working), so I can't exactly tell you how to fix this. But somewhere you should have installed a file called libSDL_gfx.dylib (probably this extension) and the error message means that CFFI is failing to find it.
using homebrew you can brew install sdl_gfx
