Re: Building "universal" binaries for MacOS

Hi Robert,

I'm curious... will your changes be rolled into the main OCIO repository?  (If not, I should probably make a patch to apply to the main one for the next time we need to update our OCIO libraries.)

Thanks again for all your help!

Cheers,
Andrea

If you do another pull the cmake file should use the internal lcms by default.

Yeah, I'm working at getting a universal version compiled now.  Thanks!

Your liblcms2 is not a universal library.  I guess it came from homebrew.  It would be very hard to detect if the system liblcms2 contains all the right architectures for the current build.  I guess some of flag could be added to the cmake file to force it to use its internal liblcms2.

Curses... google ate my reply!  A summary of what I wrote:

1.  Doing some more testing with yesterday's version, I noticed that changing the order of x86_64 and i386 changed the architecture that the two libraries are built in (it builds whichever comes first).
2.  Today's version is progress!  (Yay!  Thanks!)  tinyxml and yaml-cpp are being built as x86_64 & i386 fat binaries!  However, now it's erroring out in ociobakelut, due to the following:

ld: warning: in /opt/local/lib/liblcms2.dylib, file was built for unsupported file format which is not the architecture being linked (i386)

I'm looking into this now...

Thanks!
Andrea

It is fun to getting quoting rules right in cmake.  Please pull the git repo again and test again.

I have created a new CMakeLists.txt file but I currently do not have a way to test it.  If someone could please test the CMakeOSXArch branch on the rminsk/OpenColorIO repository (git clone -b CMakeOSXArch https://github.com/rminsk/OpenColorIO.git).

Thanks

I would like to build fat binaries with x86_64 and i386 architecture support.  I've tried passing the flag
    -DCMAKE_OSX_ARCHITECTURES=x86_64;i386
to cmake, but it appears that flag isn't being carried down to the building of libtinyxml.a and libyaml-cpp.a:

    ld: warning: in ../../ext/dist/lib/libtinyxml.a, file was built for unsupported file format which is not the architecture being linked (i386)
    ld: warning: in ../../ext/dist/lib/libyaml-cpp.a, file was built for unsupported file format which is not the architecture being linked (i386)

(Note:  I get the same errors if I try to build for just i386.)

Does anyone have any suggestions for what I can try?  Thanks!
