Parallel::ForkManager vs. Tk

b4e has asked for the wisdom of the Perl Monks concerning the following question:

hey.

i've just installed the Parallel-ForkManager-0.7.5 module on my (Win32) machine and it works fine.
that is, it only works fine in the DOS environment.

if i use Tk and call a subroutine from the MainLoop() (by Button(-command=>\&sub_routine_name); ), which forkes off children, i get the interesting error msg : 'Bizarre SvTYPE [128] at C:/Perl/site/lib/Paralell/ForkManager.pm line 289.'

does Paralell:ForkManager not work together with Tk ?
ie. is this simply a windows problem ?

thanks, b.

I love making WAGS( Wild As* Guesses :-) ). The first thing I would try is try using a different form of subroutine call. Like: `-command=> [sub_routine_name], #or -command=> sub { \&sub_routine_name }` [download] I have a feeling the way you are calling the -command, it is processed as the button is created, something you don't want. Like I said....a WAG. ;-) I'm not really a human, but I play one on earth. flash japh	[reply] [d/l]

I heard of many problems with Tk and fork() on Windows, probably depending on perl and Tk versions. So maybe you should first check if a normal fork() works on your system.	[reply]
