Hi guys, I’ve made a simple program to test the Process.create:
require ‘rubygems’
require ‘win32/process’
pgname = “C:\Program Files\VideoLAN\VLC\vlc.exe”
x = Process.create :app_name => pgname.to_s
sleep 5
Process.kill(1,x)
This works fine, but if a add at the begining
require_gem ‘activerecord’
I get a
testBug.rb:8: [BUG] Segmentation fault
ruby 1.8.4 (2006-04-14) [i386-mswin32]
(i get the segfault at the “Process.kill” line…) any ideas ?
I’m on a Windows XP Pro Edition , Service Pack 2 using ruby 1.8.4
Tks in advance,
Ze Maria

What version of win32-process are you using? As of 0.5.0 the
Process.create method returns a ProcessInfo struct. So, your code
should look like this:
Process.kill(1, x.process_id)
That may not be the issue, though, since you say it works fine until
you add the active_record gem. Can you provide the full backtrace?

Hi Daniel,
I’ve updated to win32-process 0.5.2:
"
D:\gem search win32-process
win32-process (0.5.2, 0.4.2)
Adds fork, wait, wait2, waitpid, waitpid2 and a special kill method
"
I still ve the same problem… I triedwhat you said and i get:
testBug.rb:10: undefined method `process_id’ for 1808:Fixnum
(NoMethodError)
btw I’m using ruby 1.8.4 should I upgrade to 1.8.5 ?
Tks in advance,
Ze Maria

That’s odd. It looks like you’re still using the 0.4.2 gem. Do a “gem
clean win32-process” and try again. Also, make sure you don’t have it
installed manually somewhere else. You can validate by printing out
the Process::WIN32_PROCESS_VERSION constant.
btw I’m using ruby 1.8.4 should I upgrade to 1.8.5 ?
If it still doesn’t work go ahead and try upgrading to 1.8.5.

Hi Dan,
I did a
“gem clean win32-process”
which gave me:
"
D:\Work\workspace\VlmReconhecimento>gem clean win32-process
Cleaning up installed gems…
Attempting uninstall on win32-process-0.4.2-mswin32
Successfully uninstalled win32-process version 0.4.2
Clean Up Complete
"
now when I execute a
gem search win32-process
I get:
D:\Work\workspace\VlmReconhecimento>gem search win32-process
*** LOCAL GEMS ***
win32-process (0.5.2)
Adds fork, wait, wait2, waitpid, waitpid2 and a special kill method
Which I think, it’s good, now the only version I 've is the latest
version
But I still 've the same problem…
btw the command “puts Process::WIN32_PROCESS_VERSION” doesn’t works,
I get an “uninitialized constant Process::WIN32_PROCESS_VERSION” error
Tks in advance
