Not compiling on emacs-26?

[jwiegley]

I get this when running make in src:

Thanks, I'll look into it. No, I haven't tested it with the latest Emacs versions.

[larsbrinkhoff]

The primary cause seems to be eager macro expansion, which didn't exist when I wrote this ages ago. I'm trying to rearrange code to resolve dependencies betwen macros and functions.

[larsbrinkhoff]

I'd like to fix this, but I have been busy with other tasks. @jwiegley, I'm guessing you don't have an urgent need for this to work?

[jwiegley]

No, none at all. If the answer is "check back in 2020", I'm fine with that. :)

"check back in 2020"

I also would be quite interested in using emacs-cl on Emacs 27.1.

Is there a chance for this to be fixed?

[larsbrinkhoff]

Thanks for the timely comment! I do want emacs-cl to work with the latest Emacs releases. I see a potential in the future for Emacs libraries to be able to use Common Lisp libraries, and I would be excited to see where that might lead. But unfortunatly, I'm more busy than ever, so I don't have time to work on this now.

Check back in 2030? ;-)

That said, I would be happy to work together with some contributors who are interested in resolving this. No code in emacs-cl is sacred, so I'm willing to see drastic changes and throw out support for older Emacs versions if need be.

I don't have an urgent or serious need, nor the skill to help, but I am interested in seeing if I couldn't use Emacs-CL for improving Emacs interaction with CYC through SubL.

[larsbrinkhoff]

Hello @aindilis,
Thanks for your interest. I still would like to see emacs-cl move forward, but I'm busy doing other things.

Two things stand out in particular:

• Use the new compiler/byte code support for lexical variables.
• Use the new class instance support for CLOS.
