Win32/Process at win32utils

[Ze Maria]

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,

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
