Subject UNO libraries for x86_64 on MacOSX Mountain Lion
Date Fri, 14 Sep 2012 18:56:46 GMT
I apologize if this is the wrong place for this message.

I am trying to compile a Ruby gem that connects to OpenOffice through UNO. I have it working
perfectly under linux 64bit (by compiling the x86_64 DEBs for OpenOffice and its SDK), however,
I am now trying to get it set up under MacOSX 10.8 (Mountain Lion) and am hitting a wall.

I have GCC 4.2 (via xcode) and 4.7.1 (via homebrew) installed on my system, and the ruby 1.9.3
libraries (installed for x86_64). I am actually able to get my gem to install (which compiles
for the native environment) under GCC 4.7 and x86_64, however when I try to actually use my
gem, I get the error message:

LoadError: dlopen(/Users/daniel/.rvm/gems/ruby-1.9.3-p194/gems/rubyuno-0.3.3/lib/rubyuno/rubyuno.bundle,
9): Symbol not found: __ZN4cppu11OWeakObject12queryAdapterEv
Referenced from: /Users/daniel/.rvm/gems/ruby-1.9.3-p194/gems/rubyuno-0.3.3/lib/rubyuno/rubyuno.bundle
Expected in: flat namespace

I've figured out that the bundle is not actually getting linked to the UNO libraries, as they
are built for i386. otool -L confirms:

otool -L rubyuno.bundle 
rubyuno.bundle:
	/Users/daniel/.rvm/rubies/ruby-1.9.3-p194/lib/libruby.1.9.1.dylib (compatibility version
1.9.1, current version 1.9.1)
	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 228.0.0)
	/usr/local/Cellar/gcc/4.7.1/gcc/lib/libstdc++.6.dylib (compatibility version 7.0.0, current
version 7.17.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)
	/usr/local/Cellar/gcc/4.7.1/gcc/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current
version 1.0.0)

I actually did end up getting my bundle compiled for i386 under gcc 4.2 by hardcoding the
-arch i386 flag, which gets the libraries linked into the bundle:

$ otool -L rubyuno.bundle 
rubyuno.bundle:
	@__________________________________________________URELIB/libuno_cppuhelpergcc3.dylib.3 (compatibility
version 0.0.0, current version 0.0.0)
	@__________________________________________________URELIB/libuno_cppu.dylib.3 (compatibility
version 0.0.0, current version 0.0.0)
	@__________________________________________________URELIB/libuno_salhelpergcc3.dylib.3 (compatibility
version 0.0.0, current version 0.0.0)
	@__________________________________________________URELIB/libuno_sal.dylib.3 (compatibility
version 0.0.0, current version 0.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)
	/Users/daniel/.rvm/rubies/ruby-1.9.3-p194/lib/libruby.1.9.1.dylib (compatibility version
1.9.1, current version 1.9.1)
	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 228.0.0)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 56.0.0)

However why I try to load the gem I get:

LoadError: dlopen(/Users/daniel/.rvm/gems/ruby-1.9.3-p194/gems/rubyuno-0.3.3/lib/rubyuno/rubyuno.bundle,
9): no suitable image found.  Did find:
	./rubyuno.bundle: mach-o, but wrong architecture
	/Users/daniel/.rvm/gems/ruby-1.9.3-p194/gems/rubyuno-0.3.3/lib/rubyuno/rubyuno.bundle: mach-o,
but wrong architecture - /Users/daniel/.rvm/gems/ruby-1.9.3-p194/gems/rubyuno-0.3.3/lib/rubyuno/rubyuno.bundle

This happens even if I compile ruby in "universal mode":

$ rvm list
=* ruby-1.9.3-p194 [ universal ]
$ lipo -detailed_info /Users/daniel/.rvm/rubies/ruby-1.9.3-p194/bin/ruby
Fat header in: /Users/daniel/.rvm/rubies/ruby-1.9.3-p194/bin/ruby

 cputype CPU_TYPE_I386
 cpusubtype CPU_SUBTYPE_I386_ALL
 offset 16384
 size 9348

I have been going in circles for a couple days now trying to figure out how to get this working.
I have even tried to figure out how to compile OpenOffice myself hoping that that way I'd
be able to get x86_64 libraries to work with, but that seems to be a whole other can of worms.
Does anyone have any suggestions and/or know of somewhere I can get OO compiled for Mac x86_64?

Thanks,
