HowTo Compile Ruby under Windows

Feb 12, 2015

For many of us ruby running on windows is a pain, but there might be cases when you have to overcome this pain and install ruby on windows.

Here is my steps which solved following issues I faced. It was tested on Windows XP and Windows 2003(x86):

  • securerandom.rb:156 segmentation fault

  • The procedure entry point _gmtime64_s could not be located in the dynamic link library msvcrt.dll.

  • SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

Before start

You have to install any working ruby version, becausue following RubyInstaller script is worked via rake.

Here is link for working installer which doesn’t have “entry point” bug.

Ruby 2.0.0

RubyInstaller Dev Kit

First of all, git clone the Rubyinstaller Dev kit.

git clone git://github.com/oneclick/rubyinstaller.git
cd rubyinstaller

It’s rake-based app. You can check its command by rake -T.

Dev Kit

Now we need to install dev kit

rake devkit sfx=1 dkver=mingw-32-4.6.2

Using mingw-32-4.6.2 allowed me to solve “segmentation fault”. After compilation you will have something like pkg\DevKit-mingw-32-4.6.2-20150211-0706.7z Unpack it to C:\DevKit. Make sure C:\DevKit\bin and C:\DevKit\mingw\bin are in PATH.

Ruby

Now compile ruby

rake clean
rake ruby21

If it’s successfully compiled the sandbox\ruby21_mingw folder will have ruby. Copy them to C:\Ruby21.

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

  • Download pem file

  • Copy this pem file to C:\Ruby21\lib\ruby\2.1.0\ssl_certs
