I installed the latest version of Ruby and WideStudio (Ruby 1.8.4 and WideStudio 3.94-1). I also installed the Ruby that came with WideStudio (Ruby 1.8.0). So now I have two versions of Ruby and only the one that came with WideStudio works with WideStudio. So my question is, what’s the difference? I would like to use WideStudio but I would hate to be tied into using a special version of Ruby. ---

Here’s the error (Ruby 1.8.4 precedes the widestudio version of Ruby in my path). C:\a\hello\>ruby hello.rb ./mwt.dll: [BUG] Segmentation fault ruby 1.8.4 (2005-12-24) [i386-cygwin] ``` 3 [sig] ruby 3576 open_stackdumpfile: Dumping stack trace to ``` ruby.exe.stac kdump If I run the widestudio version of ruby, it works: C:\a\hello\>\WideStudio\ruby\bin\ruby hello.rb A window appears as expected. Thanks, Sean. ---

I’m new to WideStudio, but i believe mwt.dll is the graphical library used by WideStudio/MWT. I’m not sure if it’s compatible with cygwin. I guess I should try to build a ruby-mingw32 version 1.8.4. ---

Ok, I think I figured it out. Building WideStudio/Ruby apps requires ruby-mingw32 (meaning ruby built with mingw/msys). Here’s the steps I took (instructed by Sean O’Halpin): I installed MinGW Current (MinGW-5.0.3) first, then MSYS-1.0.11-2004.04.30-1, downloaded and unpacked ruby stable snapshot (ftp://ftp.ruby-lang.org/pub/ruby/stable-snapshot.tar.gz), fired up MSYS, entered this: /configure --prefix=c:/ruby-mingw --enable-shared && make && make install ---

Congraturation. > /configure --prefix=c:/ruby-mingw --enable-shared && make && make > install On a side note, I don’t recommend to use prefix (especially, with a drive letter) on Windows, since it is meaningless but will be embedded in rbconfig.rb. Use DESTDIR=… at install, instead.
