I'm working on a macro, |enum|, that accepts a prefix and a set of
values, that expand in to a basic symbolic enumeration:
(enum my foo bar)
=>
(define my '(foo bar))
(define my-foo 'foo)
(define my-bar 'bar)
The reason for the above is immaterial, I really need help with the
error I'm

I believe the typical way to do this is to include the file after
you load csi:
$ cat my-input-file.scm
(define (doit)
(display "hello world")
(newline))
$ csi

Are there more appropriate mailing lists you could have this

I'm getting an error message when I use |(declare (block))|.
Using the same code in my previous email about invalid forwarded
object (repeated here), I declare it as an egg like so (the only
change is wrapping it around a module):
<++> csc -s -j pwent pwent.so pwent-egg.scm
(module pwent
(getpw
I have the following C function:
extern void svec_free(char **v);
And I want to call it from Scheme, so I say:
(define svec-free
(foreign-lambda void "svec_free" (c-pointer c-pointer)))
But the above (c-pointer c-pointer) declaration is a void**, not a
char**, so I get the following war
struct a record from C and want to pass it to Scheme, not just
reading the /etc/passwd file. I could rewrite this to read records
from an arbitrary file and suspect I'd still be getting this error.
Thank you,

Greetings,
I'm encountering the following error message inside a callback using
Chicken's FFI interface:
Error: (cdr) bad argument type: #

I'll throw in my two bits here.
I'm not personally decided whether utf-8 in core would be an
improvement. I don't have enough background or knowledge of
the internals to contribute to that decision.
I can offer this, however:
I have found that I have to use utf-8 support in every project

I'm running Mac OS X 10.8.2 and have just installed the latest
XCode+XCode command-line tools. I've built chicken 4.8.0, and
am trying to install the setup-helper egg. I get the following
error. I'm not familiar with install_name_tool, though I gather
it's a piece of XCode and/or some Mac OS X-s

Tony,
The mw and mw-core eggs' tests don't pass when run by salmonella:
http://tests.call-cc.org/current/salmonella-report/tests/mw.html
http://tests.call-cc.org/current/salmonella-report/tests/mw-core.html
The problem in both cases is that the *.meta file for each egg needs

Kon,
Would you update srfi-19 and srfi-29 to compile against the
experimental branch in chicken?:
http://bugs.call-cc.org/ticket/481
http://bugs.call-cc.org/ticket/482
The patch is very simple, getenv has been deprecated in favor of
get-environment-variable.
These are the only two srfi-* eg
Thomas,
The sqlite3 is still failing to compile in the experimental branch:
http://pestilenz.org/~ckeen/salmonella-report/2011-01-14/sqlite3.html
Will you apply the patches I sent you to the sqlite3 egg? Since
sqlite3 won't compile, I can't test my own packages against the
experimental branch.
I have two open tickets against the utf8 egg:
https://bugs.call-cc.org/ticket/423
https://bugs.call-cc.org/ticket/480
Both of them are simple fixes, one of them is causing several
packages not to compile against the experimental branch, which
Christian has just begun nightly builds for:
