Folks, It appears from some bugs posted on bugzilla (e.g. 5086) that WebKit is supposed to be able to build for i386 architecture, but I am not having any luck doing so. I'm trying to build WebKit as 'fat binary' -- having both i386 and Intel architectures. But I am having no luck. For instance, It's not building dftables, which is needed right off the bat: /usr/bin/gcc-4.0 -o /Volumes/BigData/build/JavaScriptCore.build/ Deployment/dftables.build/Objects-normal/i386/dftables -L/Volumes/ BigData/build/Deployment -F/Volumes/BigData/build/Deployment - filelist /Volumes/BigData/build/JavaScriptCore.build/Deployment/ dftables.build/Objects-normal/i386/dftables.LinkFileList -arch i386 - mmacosx-version-min=10.3 /usr/bin/ld: warning fat file: /usr/lib/gcc/i686-apple- darwin8/4.0.1/../../../libSystem.dylib does not contain an architecture that matches the specified -arch flag: i386 (file ignored) Am I missing something here? Is this a bug in TOT? One would think that intel compatibility would be a no-brainer at this stage in the game.... Dan Wood
