      From the IRB it should work regardless.

      I know some plugins run from other folders quite happily, but for SU it can be a problem...

      Yes, all depending on how they locate their files. My plugin uses the path to the loading .rb as base to determine the subfolders. Works fine on PC.
      I set it up in an isolated folder for development, with the development folder added to the include path.

      But it is strange that you can't even load it from IRB...

        I'm not very familiar with IRB, so it probably my error.
        maybe you could give me more specific instruction...

        when I unzip d/l file I put "TT_Hamster.bundle" into my SU plugins folder

        in SU Ruby Console I run your .rb code and get

        > require 'mkmf'
        create_makefile("TT_Hamster")
        Error; #<LoadError; (eval);507;in `require'; no such file to load -- mkmf>
        (eval);507
        (eval);507
        

        so, what am I doing wrong??

          I'm confused - are you using the SU Ruby Console or the IRB to test it?

          > require 'mkmf'
          Ohhh - now I see. That bit is what I used to compile the extension.

          TT_Hamster.bundle is the compiled result of that.
          You should only need to
          require "TT_Hamster" - this assumes that TT_Hamster.bundle is in the current working directory.

            I checked and have a similar problem. I have only been testing my extension in SketchUp on Windows and IRB on Windows/Mac. I'm going to look into it too and will post anything I find here.

              You have to link as a flat namespace otherwise it won't work on OSX.

              LDSHARED = cc -dynamic -bundle -undefined suppress -flat_namespace

                I don't know at all what that line actually do, but I replaced what was generated by the extconf.rb file:
                LDSHARED = cc -arch ppc -arch i386 -pipe -bundle -undefined dynamic_lookup

                Using that line you posted and everything worked great!

                I need to work out what it is this does. And how this make system works. I could not even recompile without erasing an .o file that was also generated last time I ran make. ❓ 😳

                Thank you very much Adam! I owe you a cookie!

                  I notice the old line had something in it, -arch ppc - would that have made it compatible with PPC macs?
                  I have an old G4 Mac Mini as well as the Intel Mac. Can I compile on the Intel mac in a manner so that the extension will run on both systems?

                    You'll need to add:

                    "-arch i386 -arch ppc"

                    to CFLAGS and DLDFLAGS

                    This will make the Mac compiler build your code for both PowerPC and Intel CPUs.

                      How did you work out that flat namespace is needed for SU Ruby? Since it isn't needed for when you use the normal Ruby?

                        I guess it'd be worth compiling this info into a how-to article...
