Issue #1092 has been updated by Heesob Park.


This is not a bug.
You tried to build 64bit ruby with 32bit compiler. If you didn't specify the target, you will succeed to build 32bit ruby.

There are several command prompts in Visual Studio 2008 Tools.
You should not run Visual Studio 2008 Command Prompt but run Visual Studio 2008 x64 Win64 Command Prompt to run 64bit compiler.
