Hello,

I have been trying to load Screamer (http://www.cl-user.net/asp/ys9U/sdataQI ... 3F$sSHnB==)
in order to work with constraints in CL.

However I am having trouble loading the package.

I am using the free edition of allegro cl 8.2

When I first tried to compile and load it I received an error message as the file was attempting "DEFTYPE BOOLEAN.."
where BOOLEAN was already defined. So I commented out the DEFTYPE.

It then loaded without errors but with numerous warnings that various named functions were not defined.

However none of the functions I had loaded were recognized.

I have tried recompiling and reloading but now it just sits on a "Fast loading.." line and does nothing.
(When I then press enter it returns to the REPL prompt.)

I am wondering whether anyone has had this or a similar experience, whether with Screamer or with another extension.

I have no prior experience loading extensions etc and may well have missed something vital. If so, any advice would be very much appreciated.

Thank you in advance!

What version of Screamer did you download? I believe the original version is not fully compatible with standardized Common Lisp. There is a modernized version available at repo.or.cz/w/screamer.git. This loads for me on current SBCL with no problems.

Hi Ramarren,

I tried the version you linked also.

No luck with it, so I think I'll try to run it on SBCL for windows and see how I get on.

Cheers

Did you type
at the REPL?
