Thanks, Matthew, it works!
I think that "ihash.scm" is being compiled twice: once when you use
`mzc' on "ihash.scm" and again when using `mzc' on
"config-enumerators.scm", assuming that you move the ".zo" files into
place only after compiling both of them. Unfortunately, due to the way
contracts expand, compiling a source file multiple times does not
necessarily produce the example same result.
It's simpler to use `raco make' (or `mzc --make' if you really want to
use `mzc' for some reason) on just your main program file. The `raco
make' command will automatically compile dependencies and leave ".zo"
files in the right place (i.e., in a "compiled" subdirectory).

Hi!
I'm having a problem with byte-compiled modules and contracts. There are
2 files, ihash.scm and config-enumerators.scm, both are compiled with
PLTCOLLECTS=/opt/dozor/racket/lib/racket/collects:/home/timur/develop/projects/d
ozor/build
LD_LIBRARY_PATH=/opt/dozor/racket/lib:$$LD_LIBRARY_PATH
/opt/dozor/racket/bin/mzc -z -d . $<
(working string from Makefile).
Small piece of ihash.scm:
#lang racket
(define (ihash? ht)
(and (hash? ht) (let ((index (hash-ref ht #f #f)))
(number? index))))
(provide/contract (ihash-get (-> ihash? any/c any/c any/c)))
(define (ihash-get ihash key default)
(let ((value (hash-ref ihash key #f)))
(if value (cdr value) default)))
Small piece of config-enumerators.scm:
#lang racket
(require (lib "ihash.scm" "lib"))
(define (section-replicable? section)
(car (ihash-get section 'replicable? '(#f))))
Before compilation both scm-s are put to
/home/timur/develop/projects/dozor/build/lib, compiled and then put to
/opt/dozor/smap/lib/lib/compiled. $HOME/.racketrc has the next command:
(current-library-collection-paths (list* "/opt/dozor/smap/lib"
(current-library-collection-paths)))
Then i run /opt/dozor/racket/bin/mzscheme,
type (require (lib "config-enumerators.scm" "lib")) and get the
following error:
link: module mismatch, probably from old bytecode whose dependencies
have changed: variable not provided (directly or indirectly and at the
expected position) from module: "/opt/dozor/smap/lib/lib/ihash.scm"
accessed from module: "/opt/dozor/smap/lib/lib/config-enumerators.scm"
at source phase level: 0 in: provide/contract-contract-id-ihash-get.14
Any ideas?
