    <p>I've been scouring SO and Google but haven't found anything helpful yet.</p> <p>We're updating our existing iOS project to build against iOS 5.</p> <p>Our project has two targets, the first is our static library and the second is a Unit Test application (GHUnit).</p> <p>When building the unit test target it successfully compiles the static library, but then fails to link against it with the following output:</p> <pre><code>Ld /Users/XXXXXX/Library/Developer/Xcode/DerivedData/XXXXXXLibrary-egoqfplddstqvwaigwuiqfqplcax/Build/Products/Debug-iphonesimulator/UnitTests.app/UnitTests normal i386 cd /Users/XXXXXX/Documents/iOS/trunk setenv MACOSX_DEPLOYMENT_TARGET 10.6 setenv PATH "/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/clang -arch i386 -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk -L/Users/XXXXXX/Library/Developer/Xcode/DerivedData/XXXXXXLibrary-egoqfplddstqvwaigwuiqfqplcax/Build/Products/Debug-iphonesimulator -F/Users/XXXXXX/Library/Developer/Xcode/DerivedData/XXXXXXLibrary-egoqfplddstqvwaigwuiqfqplcax/Build/Products/Debug-iphonesimulator -F/Users/XXXXXX/Documents/iOS/trunk -F/Users/XXXXXX/Documents/iOS/trunk/UnitTests -filelist /Users/XXXXXX/Library/Developer/Xcode/DerivedData/XXXXXXLibrary-egoqfplddstqvwaigwuiqfqplcax/Build/Intermediates/XXXXXXLibrary.build/Debug-iphonesimulator/UnitTests.build/Objects-normal/i386/UnitTests.LinkFileList -mmacosx-version-min=10.6 -Xlinker -objc_abi_version -Xlinker 2 -ObjC -all_load -Wl -Xlinker -no_implicit_dylibs -D__IPHONE_OS_VERSION_MIN_REQUIRED=50000 -framework SystemConfiguration -framework CoreLocation -framework CoreData /Users/XXXXXX/Library/Developer/Xcode/DerivedData/XXXXXXLibrary-egoqfplddstqvwaigwuiqfqplcax/Build/Products/Debug-iphonesimulator/XXXXXX.a -framework GHUnitIOS -framework CoreGraphics -framework Foundation -framework UIKit -o /Users/XXXXXX/Library/Developer/Xcode/DerivedData/XXXXXXLibrary-egoqfplddstqvwaigwuiqfqplcax/Build/Products/Debug-iphonesimulator/UnitTests.app/UnitTests Undefined symbols for architecture i386: "_llvm_gcda_start_file", referenced from: ___llvm_gcov_writeout in XXXXXX.a(NSObject+SBJSON.o) ___llvm_gcov_writeout in XXXXXX.a(NSString+SBJSON.o) ___llvm_gcov_writeout in XXXXXX.a(SBJsonBase.o) ___llvm_gcov_writeout in XXXXXX.a(SBJsonParser.o) ___llvm_gcov_writeout in XXXXXX.a(SBJsonWriter.o) ___llvm_gcov_writeout in XXXXXX.a(XXXXXXReachability.o) ___llvm_gcov_writeout in XXXXXX.a(XXXXXX.o) ...

    1. COThis error generally comes when a framework isn't available. Here I'm not sure which framework is missing, but maybe you can try figuring out missing frameworks.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
