Chipmunk extension is outdated

[IanTrudel]

The current version of Chipmunk integrated to Shoes is 4.1.0 . The latest Ruby bindings available is 6.1.3. Good news! It's available in a RubyGems. May hopefully work out of the box.

You've tagged this issue low - correctly. Although I'm fond of the sample I'm not aware of anybody using chipmunk in Shoes (how would I know?) If the gem was working with Ruby 2.3, I'd feel better about using the gem instead. I could easily be convinced to not ship the ext & sample and not include the gem either. They appear to provide a mingw binary gem so thats 80% of the audience w/o and the 20% can install xcode or use the linux package manager to install gcc.

[IanTrudel]

The latest bindings did successfully build on my machine when installing it as a RubyGems. Chipmunk is lightweight and stable. It should build right out of the box on your build environment for all Shoes targets. How about doing that, copy the gem in Shoes, like Nokogiri, Picky, etc?

[ccoupe]

did the samples/simple-chipmunk work with the gem?

[IanTrudel]

Latest version requires a DevKit. No DevKit to build Shoes here, no DevKit to build gems for Shoes. I did try chipmunk-5.3.4.5-x86-mingw32 without success. It complains about not valid UTF-8 string. There a similar issue on shoes/shoes-deprecated#265. Most likely compiling parameters are not right for Shoes. Really need to build on a Shoes DevKit to test.

The following happened when I clicked copy in the Shoes Console: (cshoes.exe:15524): Gdk-WARNING **: Failed to convert utf8: Invalid byte sequence in conversion input

Copied chipmunk.so from 6.1.3.4 compiled with Ruby 2.1.5 DevKit but got the following error. Obviously, Shoes has a newer version of Ruby.

Very good news! I installed Ruby 2.2.4 to match Shoes, compiled Chipmunk with the DevKit, moved chipmunk.so in Shoes\lib\ruby\2.2.0\i386-mingw32 and voilà! It's working right of the box, just as I said it would.

[IanTrudel]

Chipmunk integrates well with the new MSYS2 target. It actually seems faster than the older version. Replacement with the newest version highly advisable.

Fails the linux loose shoes test - gem is installed - not copied into Shoes because it shouldn't need to be - samples/simpile/simple-chipmunk fails to load the gem with require 'chipmunk'. Irb (same ruby will)

[IanTrudel]

Well, I had success with copying chipmunk.so. Notice the samples/simple/simple-chipmunk.rb is loading the wrapper shoes/chipmunk.rb which is requiring chipmunk**.so**.

It may work as a gem but shoes/chipmunk.rb may need some help.

[ccoupe]

Yes. In lib/shoes/chipmunk.rb

#require 'chipmunk.so'  #ext
require 'chipmunk/chipmunk.so' #gem

[ccoupe]

Just in case any one cares, I want to use the gem so it's no longer an ext (can delete ftsearch and chipmunk as exts) If you think this is simple here's the private task list.

done: loose: can load chipmunk.so from the gem instead of an ext.

You don't want to know about the effort on OSX and potential pilot errors with and OSX virtual machine just to install and copy.
