Facing issue to install ruby gem iconv

[javeds...@gmail.com]

I am running with issue while installing iconv ruby gem 

Ruby version:

1.ruby 2.0.0p643 (2015-02-25) [i386-mingw32]

2. Environment 64 bit window machine.

I tried below commands:

1. gem install iconv 

2. Download iconv lib and run command:  gem install iconv -- --with-curl-lib=C:\Users\Admin\Downloads\mingw64\lib --with-curl-include=C:\Users\Admin\Downloads\mingw64\include

Please help me on how to setup.

I don't use the iconv gems. But I managed to install it.

The RubyInstaller 2.0.0 package still has  its own libiconv-2.dll.
Using the same toolchain which built the binary is the first, and maybe the only, option.
The converse is also true.

Download the libiconv-1.14-x86-windows.tar.lzma from following URL
and unpack it using 7-Zip.

http://dl.bintray.com/oneclick/OpenKnapsack/x86/:libiconv-1.14-x86-windows.tar.lzma

I unpacked it and renamed the root directory to C:/DevKit-mingw64-32/home/tsuyoshi/libiconv-1.14.

C:\DevKit-mingw64-32\home\tsuyoshi>gem i iconv -- --with-opt-dir=C:/DevKit-mingw64-32/home/tsuyoshi/libiconv-1.14

Thanks for quick response.

Provided links is not working, could you please share correct link.

I downloaded but still getting same error:

[Tsuyoshi Morita]

I used only 3 archive files.

  ruby-2.0.0-p648-i386-mingw32.7z,
  DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe
and
  libiconv-1.14-x86-windows.tar.lzma

All I can advice you is,
in order to isolate the problem,
it is better to start from the installation of these files.
