Error in installing by Quicklisp with SBCL

[rudolph-miller]

when i tried to use it by sbcl, clone it on quicklisp/local-projects, register-local-projects and quickload it, then i got the error.

To load "dbi":
  Load 1 ASDF system:
    dbi

though it caused with SBCL, it didnt cause with CLISP

I've been getting this error on every SBCL newer than 1.2 for every package that uses cl-syntax. Anyone have any idea what this is about?

[rudolph-miller]

The method to avoid this problem is that adding :cl-annot to asd files, and (cl-syntax:use-syntax :annot) -> (annot:enable-annot-syntax).

Though I use SBCL 1.2.1 usually, I don't have any problems so far.

named-readtables recently got a new maintainer and made some changes. https://github.com/melisgl/named-readtables

Do you guys have the latest named-readtables?

[eudoxia0]

Yep, version 0.9. The solution @Rudolph-Miller gave works perfectly, but just about every project uses (cl-syntax:use-syntax :annot) rather than (annot:enable-annot-syntax).

[fukamachi]

Seriously? I could reproduce the issue with the older named-readtables (at https://github.com/melisgl/named-readtables/commit/d4d41e97faba296a1f89b706b573a4cba8d1fbde). Don't you have an old copy of it somewhere? (asdf:system-source-directory :named-readtables) might help.

I cloned the latest named-readtables and put it in my local-projects, then deleted all fasl files and tried again. Same error.

As an experiment, I ran git checkout d4d41e9 on the project, deleted all fasls and tried again. Same error.

EDIT: This is on SBCL 1.2.0, and on the latest SBCL. CCL works fine.

[fukamachi]

Weird. @m2ym may have some advices.

I don't have any idea but

Reader macro conflict while trying to merge the macro character #\# from

seems to say your macro character # differs from the standard that is used by annot syntax table. What do you get if you eval (get-macro-character #\#) ?

[eudoxia0]

Ok, I decided to stop building different SBCL's and instead try the different versions of named-readtables. To my surprise, switching the second-to-last commit fixed it. I made sure to run ql:register-local-projects (Where my clone of named-readtables is) and delete all FASL files from the system. I'll bring this to the maintainer of named-readtables, but I think we can consider this issue closed on this end.

[fukamachi]

Is this still happening?

[eudoxia0]

Whenever I install Quicklisp, I clone named-readtables and checkout the second-to-last commit. Otherwise, yes, it's still happening. I've been meaning to report the bug to melisgl but it might be a little hard to prove, since it apparently only happens to a select few.
