Issues with Windows Server

[mileszs]

I'm sorry; I have neither tried it on Windows, nor do I have access to Vista.

I have a virtual Windows XP, Windows Server 2003 64-bit & Windows 7 Ultimate 64-bit - all running wkhtmltopdf just - fine - but I would go to wkhtmltopdf google group to ask more info about your problem - you will probably get more help there.

I just posted my solution to a similar problem here:
http://code.google.com/p/wkhtmltopdf/issues/detail?id=162#c5

It seems to be an issue related to some wicked_pdf code after all. Maybe the suggested adjustment can be made within the main code accordingly.

Actually I discovered an additional bug related to this. Standard Open3 gem doesn't implement fork(), and that error kept coming up. Fixed it by changing require from 'open3' to 'popen4' ( a wrapper from codeforpeople). Also as suggested above by adding "b" option in line 21 of wicked_pdf.rb. Hope that helps

fixed same problem with windows 7 64bit by installing:
gem install win32-open3
and changing the require 'open3' to require 'win32/open3' (wicked_pdf.rb in plugin-dir/lib)

I am developing on windows, but running the production server at linux. how to make this require-line for both plattform individual?

[konung]

Stueck you can check against a global called RUBY_PLATFORM - windows system will spit out something like win32 or mingw32 - depending on how it was compiled .
Check out this little helper I wrote: http://github.com/konung/santas_little_helper/blob/master/lib/santas_little_helper.rb

Great, thank you very much.

Hi I am developing in windows, but my server is linux.
I did try generating a pdf with image for windows but without any lucky, however it is working fine for linux... (it doesn't matter if you are using relative path or full path)
I'd like to give my contribution to this plugin and to this thread.
I'm not quite sure how to do it, so I will just put it here, hopefull somebody can get this and add to the main branch.

First, Use konung and create a file in the lib directory, mine is platform.rb
Secondly, it is necessary to install the gem win32-open for windows
Thirdly, Change the file wicked_pdf, in the plugins lib directory
do the following:
a) Add the lines in the beging of the file, remember to remove require 'open3', it just works for linux ...
require 'platform'
if linux? || mac?
require 'open3'
else
require 'win32/open3'
end

b) add a new method for the class WickedPdf
def popen3(command_for_stdin_stdout,type, &block)
if linux? || mac?
Open3.popen3(command_for_stdin_stdout, &block)
else
Open3.popen3(command_for_stdin_stdout, type, &block)
end
end

c) Change the Open3.popen3 to use the new method created, so the pdf_to_string will be as:
def pdf_from_string(string, options=nil)
command_for_stdin_stdout = "#{@exe_path} #{options} --ignore-load-errors - - -q"
p "_"15 + command_for_stdin_stdout + ""_15 if RAILS_ENV == 'development'

popen3(command_for_stdin_stdout, 'b') do |stdin, stdout, stderr|
  stdin.write(string)
  stdin.close
  pdf = stdout.read
  raise "PDF could not be generated!\n#{stderr.read}" if pdf.length == 0
  pdf
end

end

If you've used the one-click installer to install ruby on windows, you may need to read this to get win32/open3 to work:

Could you try https://github.com/soorajb/wicked_pdf
It worked on my windows xp.

The latest versions use branching logic to figure out whether to load open3 or win32/open3 when on windows.
