[Chicken-users] csi works, but not csc

[Mark Carter]

I'm new to Scheme. I wrote a little program: cacc.scm.

When I type

    csi cacc.scm

the program runs successfully. However, when I try to compile it:

    csc cacc.scm

it prints out the following errors:

Error: during expansion of (dbind322 ...) - unbound variable:
macro-helpers#list-destruc

    Call history:

Error: shell command terminated with non-zero exit status 17920:
'/usr/bin/chicken' 'cacc.scm' -output-file 'cacc.c'

What's the problem?

Did you use any libraries from chicken that you didn't 'require'? IIRC csi imports a number of helper modules that csc doesn't. I'd check the documentation for csi or csc for exact behavior.

Can you show us the code you wrote?

I'm thinking the problem has something to do with low-level-macros.

I was really just looking for 'define-syntax-rule'. I managed to write
my own version:
(define-syntax define-syntax-rule
  (syntax-rules ()
    [(define-syntax-rule (id arg ...) body)
     (define-syntax id
       (syntax-rules ()
     [(id arg ...) body]))]))
which, to my surprise, actually works. Bear in mind that I'm a n00b to
Scheme.

So, by jettisoning the module low-level-macros and writing my own
define-syntax-rule, my program manages to compile and run as expected.

So, problem solved. Hmmm. It's a pity chicken wan't a tad more helpful
with its error messages.
