Hi

I am trying to install libxml using the command libxml-ruby and I am
seeing the following errors.

Building native extensions. This could take a while…
ERROR: Error installing libxml-ruby:

Please provide information of the Ruby version you’re using (‘gem env’
will be enough)

Appears that you’re using the VC6 build of ruby (i386-mswin32) which
requires you have Visual C 6.0 installed (no longer available)

Please confirm this, and if so, then I would recommend usage of
RubyInstaller[1] packages with the DevKit[2] to get a stable Ruby
environment with compiler.

Hi!

I can access the same environment Sirisha used.

I also made some “upgrades” there, without success. The output of ‘gem
env’:

====================

The interesting thing is, that rake complains about missing Rakefile…
and indeed, the Rakefile is not under …/lib but under
…/libxml-ruby-1.1.3-x86-mswin32-60 - I’m getting clueless… :frowning:

Ok, seems that my previous comment wasn’t clear

libxml-ruby 1.1.3 gem, compiled binary available for download here:

http://rubygems.org/gems/libxml-ruby/versions/1.1.3-x86-mswin32-60

Clearly defines Rakefile as an extension:

C:\Users\Luis\Desktop>gem spec libxml-ruby-1.1.3-x86-mswin32-60.gem
extensions

  • ext/mingw/Rakefile

Which means the Rakefile is going to be invoked when installed.

Taking a look inside the gem:

C:\Users\Luis\Desktop>gem unpack libxml-ruby-1.1.3-x86-mswin32-60.gem
Unpacked gem: ‘C:/Users/Luis/Desktop/libxml-ruby-1.1.3-x86-mswin32-60’

And looked into ext/mingw/Rakefile, which has this note on top:

We can’t use Ruby’s standard build procedures

on Windows because the Ruby executable is

built with VC++ while here we want to build

with MingW. So just roll our own…

Looking at it seems that the gem is copying files at installation
time.

So the Rakefile failure you’re receiving is either from RubyGems not
able to find it or from libxml gem itself.

I cannot comment further because I’m not either author or user of
libxml-ruby library.

Please contact the author or report a bug to their tracking system.
