What to do and how to install when an error occurs in DXRuby 1.4.7

The 2D game library "DXRuby" for Ruby for Windows has been upgraded to 1.4.7, and now supports the latest Ruby 3.0.0, and finally the 64-bit version of Ruby. However, when using it on Windows 10, I got an error and was impatient, so make a note of the notes.

important point

・ DXRuby only works on Windows

Since it uses DirectX on Windows, it does not work on macOS and Linux. Other than the Windows environment, there are libraries such as "DXOpal" and "Nyle-canvas" that can be operated with almost the same code as DXRuby (however, they are not completely compatible).

"RubyInstaller for Windows" is convenient for installing Ruby. From DXRuby 1.4.7, it supports 64-bit version Ruby (version written as " x64 "). DXRuby doesn't have to be with Devkit (MSYS2).

-In the 64-bit version, an error occurs in Sound.new

-On Windows 10, it will not work unless d3dx9_40.dll is added.

Due to this, I installed DXRuby, but when I ran it, I got an error and was impatient.

DXRuby uses the Windows DirectX 9 library. (So ​​it doesn't work except on Windows.) From Window10, DirectX 9 is no longer included, so you need to add it yourself.

3. All you need is d3dx9_40.dll, so search the unzipped folder for the necessary files according to Ruby's 64bit/32bit. ・ 64bit version Ruby (x64); Nov2008_d3dx9_40_x64.cab ・ 32bit version Ruby (x86, i386); Nov2008_d3dx9_40_x86.cab

7. Copy the resulting d3dx9_40.dll to your Windows folder. There are two ways to do it.

a) Copy it to the bin folder in the installed Ruby folder. C: \ Ruby30-x64 \ bin etc.

b) Copy to the Windows program folder.
