igem update --system issue on Windows

[Andrew Badera]

Hi all,

Running into a problem I hit when I tried to get IronRuby and RoR up on one of my Win7 machines back in March.

C:\Program Files (x86)\IronRuby 1.0v4\bin>igem update --system

Updating RubyGems

Updating rubygems-update

Successfully installed rubygems-update-1.3.7

ERROR:  While executing gem ... (Gem::Exception)

    [BUG] invalid exec_format "ir", no %s

Apparently RubyGems expects "ruby" not "ir" as the runtime executable. There's a fix:

http://rubyforge.org/tracker/index.php?func=detail&aid=27995&group_id=126&atid=575

http://gist.github.com/379763

But it doesn't seem to work for me despite putting it everyplace that the above links seem to mention:

http://www.ruby-forum.com/topic/212151#new

Anyone have any thoughts or insight for a poor ol' Windows guy?

Thx-

Is igem really a .bat file of some kind? If it inherits the cmd
prompts environment, or if you can edit it, you can create something
similar to a bash alias.

e.g.

doskey ls=dir

... the above is really handy when you are forced to used Windows cmd,
but spend most of your time in BASH.

... and to complete that thought:

doskey ruby=ir

Thanks, good idea, but no love apparently:

C:\Program Files (x86)\IronRuby 1.0v4\bin>c:\windows\system32\doskey.exe ruby=ir

C:\Program Files (x86)\IronRuby 1.0v4\bin>igem update --system

Also, I kind of wonder, since IronRuby ships with .NET 4.0 now I believe, if I'm not using igem from my explicit install and 'accidentally' getting ir from the framework built-in ... "where ir" however does give me the explicit-install ...

Oh ... not sure of the syntax but try something like this and give it
another go:

doskey ruby="ir $*"

It's probably the parameters getting chopped off ....

[Andrew Badera]

Nope :( (cleared macros first)

c:\Program Files (x86)\IronRuby 1.0v4\Lib\ironruby\gems\1.8\gems\rubygems-update-1.3.7>c:\windows\system32\doskey ruby="ir $"

c:\Program Files (x86)\IronRuby 1.0v4\Lib\ironruby\gems\1.8\gems\rubygems-update-1.3.7>ir setup.rb

It's $* -- dollar-sign + star.

Good catch, thanks, but same result.

For the time being I manually copied the contents of the Lib folder ... what a pain ... will that even work ok? I don't know enough about how Ruby works ...
