I have 1.9.1, win32-service gem looking for 1.8

Grant Birchmeier

5/7/2009 7:16:00 PM

I have 1.9.1 installed (from zip). My scripts use the win32-service
gem, so installed it with:

> gem install win32-service

This installed the following gems without error:
win32-api (1.4.0)
win32-service (0.6.1)
windows-api (0.3.0)
windows-pr (1.0.3)

When I run the script, I get this in a pop-up dialog:
"This application has failed to start because msvcrt-ruby18.dll was not
found."

And the first line of console error is:
C:/ruby/lib/ruby/gems/1.9.1/gems/windows-api-0.3.0/lib/windows/api.rb:1:in
`require': 126: The specified module could not be found. -
C:/ruby/lib/ruby/gems/1.9.1/gems/win32-api-1.4.0-x86-mswin32-60/lib/win32/api.so
(LoadError)

I *think* that means that one or more of those gems are compiled against
the older Ruby.

I'm a gems n00b. Does gems not check for this mismatch of ruby
versions?

How can I get these gems for Ruby 1.9.1?

Thanks for any help.

You hit one of the problem with binary gems and the co-existence of
Ruby 1.8 and 1.9. I've exposed the same concern here:

http://rubyforge.org/pipermail/rubygems-developers/2009-April/0...

Cleverly enough, Aaron Patterson just blogged on how to overcome this
issue, at least form the gem developer perspective:

http://tenderlovemaking.com/2009/05/07/fat-binary-gems-make-the-rockin-world...

I'm going to work with him on improve this mechanism so gem developers
can distribute binary gems painlessly at RubyForge.

If someone works on a series of patches for RubyGems, that can help
too ;-)

Thanks, that was informative.

For my immediate needs, does that mean I'm should give up and go back to
1.8 for now?

I don't expect every gem to be rebuilt, but I'm guessing that
mswin32-api and windows-api are pretty crucial to any ruby/Windows work.
I guess I'd expect that someone would have built 1.9.1 versions of these
by now, but Google is not finding any for me.

so you installed them using exactly that command?

What exactly needs to be done?

Looks like you'll either have to try and compile them from source
(conceivably possible, if you've installed the devkit [1]) or downgrade.

Yep. I ran "gem --remote list" and I didn't see a 1.9.1 version of the
gems, so I assume there isn't one.

I ended up just downgrading to the newest 1.8 release. Seems to be
working fine.
