threads in guile-1.8

threads in guile-1.8

Hello,

I have tried to move my software from guile-1.6 to 1.8.
The part using threads did not want to run.
So I tried a small test:

guile> (use-modules (ice-9 threads))
guile> (make-thread (lambda () '()))

and become a following error message:

In standard input:
   3: 0* (make-thread (lambda () (quote ())))
   3: 1  [call-with-new-thread #<procedure #f ()> #<procedure
thread-handler #>]
standard input:3:1: In procedure call-with-new-thread in expression
(call-with-new-thread (lambda () #) %thread-handler):
standard input:3:1: Function not implemented

My question is, are the threads not implemented in version 1.8 ?

Best regards,
Roman Pach

That's not good.  Which 1.8 version are you using?  ("guile --version"
will tell you.)

Yes, they certainly are implemented.  With 1.8.x CVS, I get:

neil@arudy:~/Organized/SW/Guile/guile-cvs-1.8/guile/guile-core$ ./pre-inst-guile -q
guile> (use-modules (ice-9 threads))
guile> (make-thread (lambda () '()))
#<thread 3072936880 (807aca8)>

and I don't believe there have been big changes to the relevant code
since the start of the 1.8 series.

Did you configure --with-threads ?  If not, maybe that's the problem.
(Although I still can't work out where the "Function not implemented"
message comes from.)
