cl-macro-expandall symbol definition is void

[covici]

Hi.  I am getting this immediately upon starting emacs 24.4-rc1.  How do
I even troubleshoot as it seems to be something in my .emacs file?

Thanks in advance for any suggestions.

You can start emacs with -Q option to exclude your init file... `emacs -Q'

hmmm, I found that the problem was caused by something called
csharp-mode which I had emerged from the repository, so I don't know
what it is about emacs-24 which caused me to get that error in that
file, no way to debug your init -- is there?  I thought I remembered
some way to do that.

Your init file is just a library like any other as far as Emacs is
concerned.  As Kelvin said, you just start with `emacs -Q' to ensure a
clean environment, and as he didn't say, then you do whatever you do
to debug any library.  You lose the convenience of your
customizations, that's all.

So, does anyone know about csharp-mode and why it would give me this
error?

I think I have some idea of what's the underlying problem (in cc-mode,
used by csharp-mode).  Try:

    emacs --debug-init

and hopefully you'll get a backtrace.  In any case, open a bug with `M-x
report-emacs-bug` so we can track it there.

If you're attempt to open some C#-files using the current Emacs 24.4
Windows-build, a bug in cc-defs.el is triggered during the
initialization of csharp-mode, and the mode fails to load.

This code here, while not the "production" fix, illustrates what goes
wrong:
https://gist.github.com/bsuh/f8b12b0d7e15f75f9a7c

The current fix in the repo can be found here:

237bf45a (Stefan Monnier      2014-10-29 23:50:15 -0400  177)
(eval-and-compile
237bf45a (Stefan Monnier      2014-10-29 23:50:15 -0400  178)  
(defalias 'c--macroexpand-all
237bf45a (Stefan Monnier      2014-10-29 23:50:15 -0400  179)     (if
(fboundp 'macroexpand-all)
237bf45a (Stefan Monnier      2014-10-29 23:50:15 -0400  180)        
'macroexpand-all 'cl-macroexpand-all)))

That commit should (hopefully) contain the rest of the patching needed,
but it's mostly just applying the wrapper function instead of
cl-macroexpand-all directly.

Any chance of getting a new 24.4 build built for the Windows-users with
this patch built in?

Can't you work around this with just

(require 'cl)

?

Following diff seems to make csharp-mode-0.8.5.el work fine for me.
(Without the `eval-and-compile', it was uncompilable in any Emacs 24.x.)

Since it uses eg `set-difference', IMO it should in any case explicitly
require cl and not rely on its other dependencies pulling it in.

While I can work aroud this bug by this patch or a similar, I think it's
worth noting that csharp-mode worked fine prior to Emacs 24.4.

This means that some changes in core emacs now breaks derived c-modes.

So yes, we can work around this in csharp-mode (for now), but are we
100% sure we haven't broken any other derived c-modes in the process?

Wouldn't it be better to have this fixed in the -official- Emacs version
being distrubuted from the GNU website? If building Emacs from source
(master-branch) right now, the issue is already fixed. We might just
need a new build and that's it.

We don't disagree it's a bug in Emacs-24.4.  We're just pointing out how
to work around it.

It's not just "a new build" but a new *release*.

As I noted, for me it fails to compile in any Emacs 24.x.

Experience shows that lots and lots of people don't compile
their packages.  Even the package's own authors often don't byte-compile
the package on which they work.

Maybe one way to improve this situation is to get flymake.el to be
enabled by default in Elisp buffers.

Fair enough. Since csharp-mode seemed utterly dead (no changes on Google
code since 2011, lots of abandoned issues), I've converted and forked
the repo and put it on Github:

https://github.com/josteink/csharp-mode/

I've applied the fix there, and will contact the relevant package-repo's
for change of package-ownership for csharp-mode and get a publishing
pipeline set up.

Which I guess settles the issue for me.

It would be good to get copyright paperwork for it and to move it into
GNU ELPA.
