At first glance, it may be a Fiddle problem.

  1. Can you call Fiddle?
require 'fiddle'
  1. If it does, what version of Fiddle do you have?
require 'fiddle'
p Fiddle::VERSION

The VERSION constant was added recently, so it may not exist. It means that it is prior to 1.0.0.

How did you install Ruby on Windows? RubyInstaller?

in msys2, pacman -Syu update system pacman -S mingw-w64-i686-libffi

then in cmd :gem install fiddle irb(main):001:0> require 'fiddle' => false irb(main):002:0> p Fiddle::VERSION "1.0.8" => "1.0.8"

Thanks.

Sorry, It doesn't seem to be a fiddle problem. It seems that libui.dll cannot be loaded. LibUI problem.

First, we need to find out if libui.dll exists.

/Ruby25/lib/ruby/gems/2.5.0/gems/libui-0.0.8/vendor/libui.dll

Check the file size and make sure the file is not corrupt. image

Only ofr 64 bit Ruby? 答复111

kojix2 commented 3 years ago

Only the 64bit version is packed in the Gem. (´-ω-`) Other versions are distributed on the libui site. If you replace it, it might work.

https://github.com/andlabs/libui/releases/tag/alpha4.1

kematy commented 3 years ago

Thank you

kojix2 commented 3 years ago

Now I can reproduce the issue.

Ruby libui.dll work?
Ruby+Devkit 2.5.9-1 (x86) libui-alpha4.1-windows-amd64-shared.zip Not work
Ruby+Devkit 2.5.9-1 (x86) libui-alpha4.1-windows-386-shared.zip OK

Thank you for your report. If there are no further problems, please close it.

kojix2 commented 3 years ago

Updates Added a task to the Rakefile to download the 32-bit libui shared library.

rake vendor:all_x64      # Download libui.so, libui.dylib, and libui.dll to...
rake vendor:linux_x64    # Download libui.so for Linux to vendor directory
rake vendor:linux_x86    # Download libui.so for Linux to vendor directory
rake vendor:mac_x64      # Download libui.dylib for Mac to vendor directory
rake vendor:windows_x64  # Download libui.dll for Windows to vendor directory
rake vendor:windows_x86  # Download libui.dll for Windows to vendor directory

So, you can install it as follows

rake vendor:windows_x86
rake install

Oddly enough I re-installed the Win10 laptop and I ran into the exact same issue.

The strange thing is that prior to the re-installation, that issue did not happen.

Right now I am a bit confused how this error shows up. I don't recall what I did different prior to the reinstall; always installed via "gem install libui".

Note that require 'fiddle' and Fiddle::VERSION works. But require 'libui' fails with a "No such file or directory" Fiddle::DLError.

Is there some path issue perhaps? I can start "irb" from cmd.exe just fine and "ruby -v" shows the most recent ruby version (which is ruby 3.0.3).

kojix2 commented 2 years ago

@rubyFeedback Please tell us a little more about your environment. Did you use RubyInstaller to install Ruby, and is Ruby really a 64-bit version? Obviously using a 32bit version of Ruby will cause problems, but other causes are less clear and need to be investigated.

kojix2 commented 2 years ago

One way to tell 64bit Ruby from 32bit Ruby is to use ruby -e "puts 1.size"

If it is 4, it is 32-bit, and if it is 8, it is 64-bit.
