Subject: 25.0.50; 'Invalid slot type: semanticdb-project-database-file,
 reference-directory, string, nil' with semantic-mode
Date: Tue, 7 Apr 2015 11:20:34 +0100

With the current head of the master branch, I get the error in the
subject line whenever I try to open a file with semantic mode enabled. I
can reproduce this with '-Q' as follows:

  new-emacs.sh -Q --eval '(semantic-mode t)' --eval '(find-file "test.c")'

(where new-emacs.sh is just a shell script that calls my locally
compiled Emacs).

Setting debug-on-error gives the following stack trace:

  Debugger entered--Lisp error: (invalid-slot-type semanticdb-project-database-file reference-directory string nil)

In case it's relevant, the /home/ruperts/.emacs.d/semanticdb directory
does not exist.

I last compiled myself a new Emacs a couple of weeks ago, so whatever
change has broken things seems to have appeared in the meantime.

Duh, indeed.  I installed the patch below which should fix this blunder,

	Should I expect it to fix bug#20259 just as well?  (I hope to
	check it myself later.)

I don't know.  I share Paul's impression that it might be
a bootstrap problem.  The .elc files are not placed in the build
directory but in the source directory (I know, it's weird), so I don't
think your script reproduces the behavior of "make bootstrap".

	The call to ./configure is obviously missing here:

	My point is that the error message is exactly the same for
	either report:

Invalid slot type: semanticdb-project-database-file, reference-directory, string, nil

	I know; it is.  And that’s the whole point of using lndir(1):
	to create a symlink-based “shadow” of the /source/ directory and
	use it as the build one.

 > so I don't think your script reproduces the behavior of "make

	Per emacs-2015-04-07-build/config.status, srcdir is ‘.’.
	If there’s no .elc in the directory $ make is invoked from
	(and the ‘grep’ line in my script above ensures that), where
	else would the build process find any .elc files to use?

Than I misunderstood your script.  Does the recent patch fix your problems?

	At the very least, I no longer observe the issue with
	85c3e1be2418 (2015-04-17 04:32:33 +00:00), so I close #20259.
	And also merge it with #20270, as it looks like the same bug.

	Thanks again for the fix.
