I have asked a question on SuperUser about updating Ruby version in Google SketchUp

  • 0

I have asked a question on SuperUser about updating Ruby version in Google SketchUp. It seems that there is something different between Ruby shipped with the standard OS X distribution, and Ruby installed by RVM or MacPorts. I get the following error message when I try to use RVM’s or MacPorts’ Ruby 1.9.1

Exception Type:  EXC_BREAKPOINT (SIGTRAP)

Dyld Error Message:
  Library not loaded: @executable_path/../Frameworks/Ruby.framework/Versions/A/Ruby
  Referenced from: /Applications/Google SketchUp 7/SketchUp.app/Contents/MacOS/SketchUp
  Reason: no suitable image found.  Did find:
    /Applications/Google SketchUp 7/SketchUp.app/Contents/MacOS/../Frameworks/Ruby.framework/Versions/A/Ruby: mach-o, but wrong architecture
    /Applications/Google SketchUp 7/SketchUp.app/Contents/MacOS/../Frameworks/Ruby.framework/Versions/A/Ruby: mach-o, but wrong architecture
    /usr/lib/Ruby: not a file

Model: MacBookPro7,1, BootROM MBP71.0039.B05, 2 processors, Intel Core 2 Duo, 2.4 GHz, 4 GB, SMC 1.62f5

But it works with Ruby 1.8.7 from /System/Library/Frameworks/Ruby.framework/

UPDATE1

As it was explained by Alex I need to compile Ruby with i386 architecture. One can do it for MacPorts and RVM, but none of the methods worked for me due to various errors.

  1. How to forece i386 build on snow leopard macports ?
  2. Internal config files
  3. Darwin OS

So I decided to compile Ruby 1.9.2-rc2 from sources 

$ ARCHFLAGS="-arch i386"  CFLAGS="-arch i386" LDFLAGS="-arch i386" ./configure  --with-arch=i386
$ make && sudo make install

and copy corresponding files to SketchUp

$ cd /Applications/Google\ SketchUp\ 7/SketchUp.app/Contents/Frameworks/Ruby.framework/Versions/A/
$ rm -r Headers Ruby
$ cp /usr/local/bin/ruby Ruby
$ mkdir Headers
$ cp /usr/local/include/ruby-1.9.1/i386-darwin10.4.0/ruby/config.h Headers/
$ cp /usr/local/include/ruby-1.9.1/ruby.h Headers/
$ cp -r /usr/local/include/ruby-1.9.1/ruby/* Headers/
$ ls Headers
backward/   defines.h   dl.h        intern.h    missing.h   re.h        ruby.h      util.h      vm.h
config.h    digest.h    encoding.h  io.h        oniguruma.h regex.h     st.h        version.h

This time I have got the following message

Dyld Error Message:
  Library not loaded: @executable_path/../Frameworks/Ruby.framework/Versions/A/Ruby

    Looks like you have versions of the Ruby library in the sketchup directories for two architectures (probably 32-bit intel, and PPC, I’d guess) and are trying to use a Ruby binary built of a third and different architecture (probably 64-bit intel, I’d guess). You can check with the arch command at a Terminal.App shell prompt.

    If this should indeed prove to be the problem, you could maybe try to build a 1.9 ruby from sources, targeting 32-bit intel CPUs…? (I don’t know of any prepackaged ruby 1.9 for mac built for 32-bit intel CPUs — of course, there might well be some I don’t know about!-).
