[Jscheme-user] I must be doing something wrong...

[Glyn T. G. <qu...@ma...>]

Hello everyone,

I just bought a new laptop and I am having problems getting JLIB to work
properly.
I downloaded and installed the newest version of jscheme from
sourceforge this
evening.  After adding it to my classpath it works just fine as long as
I do not
use any of the JLIB macros.

No matter what I have tried, I cannot get JLIB to work.

I am running Linux Mandrake 8.2 (kernel 2.4.18) and java 1.4.0.

Below is the source code for the sample programme (directly from the web
site)
with a few extra includes that I needed to get it to compile.

(import "java.lang.*")
(import "java.awt.*")
(import "java.awt.event.*")
(import "jlib.*")
(import "jlib.JLIB")
(import "jsint.*")
(import "java.lang.Math")

(define win (window "Hello")
     (border
         (north (label "Hello"))
         (center (button "Goodbye" (action (lambda (e) (.hide win)
(System.exit 0)))))
         (south (label (string-append "sin(PI) = " (Math.sin Math.PI$))))))
(.pack win)
(.show win)

The runtime complains as follows:

$java Hello2
Exception in thread "main" SchemeException:[[ERROR: undefined variable
"window",#null]]
         at jsint.E.error(E.java:14)
         at jsint.E.error(E.java:19)
         at jsint.Symbol.getGlobalValue(Symbol.java:74)
         at Hello2.init(Hello2.java:114)
         at Hello2.load(Hello2.java:60)
         at Hello2.load(Hello2.java:65)
         at Hello2.main(Hello2.java:70)

Any assistance will be greatly appreciated.

Thanks,
