Fail to load the win32-api gem when running OCRA

Ruby
1

Hi,

I’m trying to run ocra but I seem to have a problem with win32-api. I’m
running this on cygwin and have also tried in an Ubuntu server. Running
ocra outputs an error that tells me to install win32-api, which I do,
but after that I still get the same error.

I’ve also tried running ocra with --no-autodll option but then the
resulting exe file won’t run.

I don’t know what I’m missing. I hope somebody can help. Thanks a lot!

Cheers, Manuel

PS: Is this the right way to send my commands? Or should I send an
attached text file?

OCRA tries to load win32-api using “require ‘win32/api’”. It looks
like Ruby is trying to load the api.so library, but gets a permission
error. This could be because the library is already open. How do you
load it from your script? (Can you post a simple example script that
reproduces the error?)

What error do you get when using --no-autodll?

Here is my sample script which works with ocra-1.1.2:

require ‘win32/api’
exit if defined?(Ocra)
Win32::API.new(‘MessageBox’, ‘LPPI’, ‘I’, ‘user32’).call(0, “Hello,
World!”, “Greeting”, 0)

Does ocra work with Linux or another unix-like environment? I thought,
it’s only runnable on Windows, because of win32-api. However, with
–no-autodll I get this on Ubuntu 9.04:

ocra t.rb --no-autodll

I would suggest trying it on a real Windows, not cygwin.
