hi all: i have some functions already in c, and want to provide ruby interfaces that can be used in sketchup 2014’s ruby console. os is win7 what i am done: - download ruby source code : ruby-2.0.0-p247.tar.bz2 - compile it use vs 2008 x86, - wrap my c functions, and write a extconf.rb - use ruby-2.0.0-p247/build/bin/ruby.exe extconf.rb to generate a dll ( ext\_ruby.so ) - > ruby-2.0.0-p247/build/bin/irb > require ‘somepath/ext\_ruby’ work but when load ext\_ruby.so in sketchup’s console. it compains error 126. and copy msvcr90-ruby200.dll to c:/program files(x86)/sketchup/sketchup2014 folder it complains incompatible library version so, some one give me a direction ? or there have a tutorial do the same thing ? many thanks ---

Hi! I’ve written a C program which runs good as an exe, and would like to create a Sketchup Extension from it… I’ve tried to start with the github HelloWorld project, but did not manage to create the appropriate rb file to get it work… I recieve an error message: Error: 193: %1 ist keine zulässige Win32-Anwendung. - path of .so file which means “is no valid” Win-32 application… what did I do wrong? see also: > > > Hi, > I'm trying to get this HelloWorld project for SketchUp running with win7 wi…th VS 2015 and SU2016 - I t I do it would try it without "SWING" > without success... > I'm missing the ruby code or extension; that would run .so file, and did not manage to make it based on the SketchUp extension su\_create\_layout\_file... > > the same problem the other way around: > \*\*I've written a C program which runs good as an exe, and would like to create a Sketchup Extension from it...

Make sure you are compiling the appropriate target for your machine - Win32 or 64 bit. ---

Thanks Jim, In fact I’m able to run the exe file even from ruby console in SU with “system”, but I’d like to go a step further… … to be able to “require” the compiled executable and to run a specific command in it. (and passing arguments like in the su\_create\_layout\_file extension…) I’m not a “real software engineer”, so it might still be that your hint to win32 and win64 is correct… ---

> [@molnar.a.hu](#): > > to be able to “require” the compiled executable This may be the base of your problem. You can “require” a Ruby or a compiled Ruby extension dll, you can’t “require” an .exe. ---

I’m on a Mac, so I’ll have to defer to a Windows expert regarding Visual Studio setup to compile a Ruby extension dll vs an executable .exe. ---

I am having issues with incompatible library version within Sketchup 2017 too: ``` Error Loading File /Users/***/Library/Application Support/SketchUp 2017/SketchUp/Plugins/MyPlugin/core.rb Error: # /Applications/SketchUp 2017/SketchUp.app/Contents/Frameworks/Ruby.framework/Versions/2.2/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require' /Applications/SketchUp 2017/SketchUp.app/Contents/Frameworks/Ruby.framework/Versions/2.2/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require' ``` I can run my plugin for SU2016 with Ruby 2.0, but I can’t get past the error above with SU2017. I am using Ruby 2.0 Framework for SU2016, and Ruby 2.2 for SU2017. I have tried as much as possible to emulate the settings and use files from this project: [GitHub - SketchUp/ruby-c-extension-examples: Ruby C extension examples](https://github.com/SketchUp/ruby-c-extension-examples) … but no luck. I think I really need help!
