Thanks Marc,

Unfortunately compiling that srf-1.scm contained therein resulted in the exact same errors. I used

gsc -dynamic srfi-1.scm

as specificied by the compile script.

I have also tried BlackHole, Snow, and Slib, and could get nothing working with either of them. If you all recommend BlackHole though then perhaps I'd better try again and direct my questions there.

Please check the Gambit dumping grounds (http://dynamo.iro.umontreal.ca/~gambit/wiki/index.php/Dumping_Grounds). I've just put Guillaume Germain's SRFI-pack which contains several SRFIs for Gambit, including SRFI-1.

Greetings all,

I downloaded and compiled the reference SRFI-1 implementation, http://srfi.schemers.org/srfi-1/srfi-1-reference.scm. I load the compiled version into gambit (after loading syntax case), but everytime it starts up I recieve these errors:

lewis@1710:~$ gsc *** WARNING -- Variable ":optional" used in module "1-list-library.o1" is undefined *** WARNING -- Variable "let-optionals" used in module "1-list-library.o1" is undefined *** WARNING -- Variable "start" used in module "1-list-library.o1" is undefined.

The only reference in the SRFI itself I can find is this

;;; The code has only these non-R4RS dependencies: ;;; A few calls to an ERROR procedure; ;;; Uses of the R5RS multiple-value procedure VALUES and the m-v binding ;;; RECEIVE macro (which isn't R5RS, but is a trivial macro). ;;; Many calls to a parameter-checking procedure check-arg: ;;; (define (check-arg pred val caller) ;;; (let lp ((val val)) ;;; (if (pred val) val (lp (error "Bad argument" val pred caller))))) ;;; A few uses of the LET-OPTIONAL and :OPTIONAL macros for parsing ;;; optional arguments.

Does anyone know how I can get these macros in gambit? (all the list procedures i want appear to work, but the error messages are annoying.)

Adrien,

No I did not try and define them myself. I am obviously a scheme novice.

Googling revealed to me that these are two very well known macros. It failed to bring up an implementation or a SRFI-number.

If you know where one should look, perhaps you could share a link.

The readme says it only works well with the interpreter.

They are indeed undefined. Did you try to define them yourself? If you don't understand the code, a little googling should tell you what they do…

It's just two very simple macros. Here's the first (not tried, not guaranteed):

(define-macro (:optional foo bar) `(let ((x ,foo)) (if (pair? x) (car x) bar)))

For what the second is and does, google is your friend. I think found it immediately.

Thankyou Bradley, works great :) And even includes iota.

I might put this on the wiki, if that's fine with you.

Try

http://www.math.purdue.edu/~lucier/gambit-srfis/srfi1.scm

It compiled and loaded without complaint, but I can't say I've tested it at all.
