Hi Shantonu, Thanks for the quick reply! On Fri, Sep 21, 2012 at 10:06 PM, Shantonu Sen <ssen@apple.com> wrote:
Are you sure you are building with -mmacosx-version-min=10.7?
10.6 actually, though I've just tried with 10.7 and that doesn't help either. (Neither does switching between the 10.8 and 10.7 base SDKs, or between clang 4.1 and GCC-llvm) It's very reproducible: - create a new I/O Kit kext project - change deployment target to 10.7 or below - Architectures to 32/64-bit Intel - either set "Build Active Architecture Only" to "No" or just build the 32-bit version. Even this minimal kext will have the two rogue segments: LC_FUNCTION_STARTS is 8 bytes in this case, LC_DATA_IN_CODE zero, as in my case. Doesn't matter if XCode 4.5 is running on Lion or Mountain Lion.
What is your full link line for your i386 kext?
XCode tells me the linker command line is: "/Applications/Xcode 4.5.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++" -arch i386 -isysroot "/Applications/Xcode 4.5.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk" -L/Users/phillip/Library/Developer/Xcode/DerivedData/ssdcache-hcwibjofejcnjvgtslhyzwfqkkty/Build/Products/Debug -F/Users/phillip/Library/Developer/Xcode/DerivedData/ssdcache-hcwibjofejcnjvgtslhyzwfqkkty/Build/Products/Debug -filelist /Users/phillip/Library/Developer/Xcode/DerivedData/ssdcache-hcwibjofejcnjvgtslhyzwfqkkty/Build/Intermediates/ssdcache.build/Debug/ssdcache.build/Objects-normal/i386/ssdcache.LinkFileList -mmacosx-version-min=10.6 -Xlinker -no_function_starts -Xlinker -kext -nostdlib -lkmodc++ /Users/phillip/Library/Developer/Xcode/DerivedData/ssdcache-hcwibjofejcnjvgtslhyzwfqkkty/Build/Intermediates/ssdcache.build/Debug/ssdcache.build/Objects-normal/i386/ssdcache_info.o -lkmod -lcc_kext -o /Users/phillip/Library/Developer/Xcode/DerivedData/ssdcache-hcwibjofejcnjvgtslhyzwfqkkty/Build/Intermediates/ssdcache.build/Debug/ssdcache.build/Objects-normal/i386/ssdcache The "-Xlinker -no_function_starts" is not normally there, of course.
