Problem installing LibCurl + LibXML + FeedZirra on Windows XP.

Question

Hi,

I am rails newbie. I am working on Windows XP.

I have this version of ruby.

ruby 1.8.7 (2010-08-16 patchlevel 302) [i386-mingw32]

I have Rails 2.3.8 installed.

I am trying to install feedzirra trying every possible way after watching the Rails Cast 168.

First I tried to install using gem install pauldix-feedzirra. I got this error.

    C:\Ruby>gem install pauldix-feedzirra
    Building native extensions.  This could take a while...
    ERROR:  Error installing pauldix-feedzirra:
            ERROR: Failed to build gem native extension.

    Could not create Makefile due to some reason, probably lack of
    necessary libraries and/or headers.  Check the mkmf.log file for more

    Provided configuration options:

            --with-opt-lib
            --without-opt-lib=${opt-dir}/lib

            --ruby=C:/Ruby/bin/ruby
            --with-curl-dir
            --without-curl-dir
            --with-curl-include

            --with-curl-lib
            --without-curl-lib=${curl-dir}/lib
            --with-curllib
            --without-curllib
    extconf.rb:12:   Can't find libcurl or curl/curl.h (RuntimeError)

      Try passing --with-curl-dir or --with-curl-lib and --with-curl-include
      options to extconf.

Next I tried gem install curb. I found this on PaulDix FeedZirra page where he had suggested us that Todd Fisher is working on Ruby binding of libcurl which is called curb

Now, I am getting this error

C:\Ruby>gem install curb
Building native extensions.  This could take a while...
ERROR:  Error installing curb:

When the error said its because it cant find libcurl or curl/curl.h then I did some googling about it and I found link to Download Wizard. The best option for a rails newbie is to go with curl executable (as suggested ascross various forums and articles) I did that. Extracted the file. Installed the exe file. Now I thought the libcurl problem is solved. But??

Ok, now inorder to install feedzirra, i need to install libxml too. So with a little bit of googling i ended up here at Libxml ruby forge, downloaded the libxml-ruby-1.1.3 gem and placed it in C:\Ruby\bin folder.

Now, thinking that all set, I am ready to go to learn feed parsing, i enter gem install pauldix-feedzirra. I get the same error "Can't find libcurl or curl/curl.h" and the same old list what i got earlier.

For the past 3 days, I am just trying to install this. No luck!

Could someone help me fix this? Basic steps. Please think I dont know how to operate windows. Please go to that basic level when you talk problem fixing terminology and help me to fix this problem.

Looking forward for your help and support in a big way.

Thanks in advance.
