Unknown error when compiling

[shys...@gmail.com]

I get a strange error when Inform 7 attempts to create code in the
Inform 6 compiler. The picture of a crescent moon shows at the top of
the screen. Relevant information of the error message :
----
C:\Program Files\Inform 7\Compilers\inform-631 \
-wSDG +include_path=..\Source,.\ auto.inf output.ulx
Inform 6.31N for Win32 (6th January 2008)
auto.inf(38235): Error: Variable must be defined before use:
"rulechange_sp"
> Global rulechange_sp
Compiled with 1 error and 1605 suppressed warnings (no output)

Compiler finished with code 1

-----
What on Earth I have 'not defined' and how do I fix this?

I recognize that variable. It's defined in the Standard Rules,
regarding rulebooks. Have you been doing anything tricky with the
Standard Rules?

What was the last thing you put into your code before this started
cropping up?

That's the thing, I didn't. My program worked fine until I upgraded to
the newest version of Inform and updated the extensions. I have no
idea what it doesn't like now that it was hunky-dory with last time.
All I can think to do is update the extensions...again. (corrupted
download, maybe?) Would it be possible to manually define that
variable?

Well, that's the trick: it's throwing the error ON the definition.
Plus, that I6 code is almost definately correct. Maybe re-download
and re-install Inform 7, perhaps after removing it from your system.
But this error is probably the result of some code clash.

Do you have other projects to test? Try making a dummy one that uses
whatever extensions you're referring to. Or knock out the extensions
one by one in the real project, making stand-ins so it will compile,
and eventually you should find a culprit somewhere.

Did you write any of the extensions? If not, which ones are they?
I've heard a few people have been having issues with Conversation
Framework lately....

Are you maybe using the Conditional Backdrops extension? It uses this
variable, but no longer works under the current build of Inform.

That I am doing! I'll see about this ASAP.

Gee, I'm embarrassed I missed that (and I read the original post...).
Take a look at section 8.8 of the documentation, which gives a new way
of specifying locations of backdrops. You should be able to do
everything that Conditional Backdrops did using the "move the ..
backdrop to all..." phrase (so I don't plan to update the extension,
but if it's really integral to your project let me know and I can try
to patch it for you).
