Jupyter and Common Lisp

I'm trying to install cl-jupyter (A common-lisp kernel for Jupyter), and I can't make it work: when I open a new lisp notebook (or change the kernel of an existing notebook), it crashes after displaying the following messages:

[I 18:26:50.855 NotebookApp] Kernel started: ccba815a-9065-4fad-9d95-06f6291136d2

Some details:

Jupyter works fine with python (both 2x and 3x).
sbcl also seems to work fine (I'm just starting with common-lisp, so I might be missing something - but I can run code, and use asdf and quicklisp).
I installed it by running "python3 ./install-cl-jupyter.py".
My .sbclrc file now contains just "(load "~/quicklisp/setup.lisp")".

System Information:

OS: Linux 4.1.13-1-MANJARO x86_64 GNU/Linux
Python 3.5.0
SBCL 1.3.0
Jupyter version 4.0.6

Some things I've tried:

The file ~/.ipython/kernels/lisp/kernel.json contains:

{"argv": ["sbcl", "--non-interactive", "--load", "/home/myusername/lisp/systems/cl-jupyter/cl-jupyter.lisp", "/homemyusername/lisp/systems/cl-jupyter/src", "/home/myusername/lisp/systems/cl-jupyter", "{connection_file}"], "display_name": "SBCL Lisp", "language": "lisp"}

All the paths are correct. When I run the same code manually:

sbcl --non-interactive --load "/home/myusername/lisp/systems/cl-jupyter/cl-jupyter.lisp" "/homemyusername/lisp/systems/cl-jupyter/src" "/home/myusername/lisp/systems/cl-jupyter" kernel-07e04903-c562-4c67-bcc1-b68f4047d8d2.json

(where "kernel-07e04903-c562-4c67-bcc1-b68f4047d8d2.json" is an auto-generated file for a lisp-kernel that I saved), it "looks ok" (e.g. it runs, and waits with no errors).

I tried to do some quick debug-printing, and my best guess is that it crashes in src/shell.lisp, in the line

 (vbinds (identities sig msg buffers)  (message-recv (shell-socket shell))

But again, I could be wrong. Since it kinda looks like it has something to do with communication, I made sure that zeromq is updated.

I'm not sure what's next besides learning some more lisp, and then come back to properly debug the code - but I was hoping to learn it using Jupyter :)

I'd appreciate any suggestions, Thanks.

This issue is caused by a change in the size of the message structure, zmq_msg_t, in 0MQ version 4.1.x to 64 bytes from a size of 32 bytes in version 4.0.x.

The 0MQ interface library used by cl-jupyter is pzmq, and that library is stated to support 0MQ up to version 4.0. At the time of this writing, pzmq uses a 0MQ message size of 32 bytes. This leads to internal errors if 0MQ version 4.1.x is installed.

There are two solutions here:

Downgrade the 0MQ installation to version 4.0.x
Fix the pzmq library by updating the definition of msg% in c-api.lisp from 32 to 64 bytes.

Update - 9 May 2016

The pzmq library was updated to support 0MQ version 4.1.x, (preserving compatibility with older versions). The new version of pzmq is planned for release as part of the May 2016 Quicklisp release.

Update - 1 June 2016

The May 2016 Quicklisp release includes updates to the pzmq library which resolve this issue. A downgrade of 0MQ or modifications to the pzmq library are no longer necessary.
