It looks like a frequent error, but after 2 days, I still did not find the definite solution to this issue.
I installed Ruby 2.0.0-p451 (x64) and DevKit (DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe) from RubyInstaller for Windows. Ruby -v returns:
ruby 2.0.0p451 (2014-02-24) [x64-mingw32]
Now, I run gem install tiny_tds, which returns:
E:\>gem install tiny_tds
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing tiny_tds:
ERROR: Failed to build gem native extension.
E:/Ruby200/bin/ruby.exe extconf.rb
checking for iconv_open() in iconv.h... no
checking for iconv_open() in -liconv... no

libiconv is missing.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
Actually, the only libiconv I have on my system is E:\Ruby200\bin\libiconv-2.dll
I tried all I could find around without success, but I'm sure there is a smart answer to this. Can you please help me find it ?
Thanks a lot,
Best regards,
Fred
