Building "universal" binaries for MacOS

Andrea Mantler <man...@...> #1314 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!

rmi...@... #1316 I am working on a patch right now but it looks like you may be able to use CMAKE_TOOLCHAIN_FILE in the meantime. You would make a file Toolchain-osx-fat.cmake with: SET(CMAKE_OSX_ARCHITECTURES x86_64 i386) Then use the flag -DCMAKE_TOOLCHAIN_FILE=<path to file>/Toolchain-osx-fat.cmake where <path to file> is the full path to Toolchain-osx-fat.cmake I am currently not in a position to test this. Please tell me if it works. toggle quoted message Show quoted text On Monday, May 26, 2014 2:12:58 PM UTC-7, Andrea Mantler wrote: I would like to build fat binaries with x86_64 and i386 architecture support.

Andrea Mantler <man...@...> #1322 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...

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!
