[Interest] How make qmake set build settings for iOS to avoid manual Xcode "Update to recommended settings” ?

Solved, mostly….

Everything except an issue “Automatically Select Architecture” which I though ONLY_ACTIVE_ARCH would fix.

Maybe I do not want this fixed for Jenkins CI builds.


# Use QMAKE_MAC_XCODE_SETTINGS to set Xcode build settings in the quake project file:

ios {





    # Set "Target"

    QMAKE_IOS_DEPLOYMENT_TARGET = 6.0


    # Set "Devices" (2=iPad Only)

    # Note for devices: 1=iPhone, 2=iPad, 1,2=Universal.

    #

    # warning: User supplied UIDeviceFamily key in the Info.plist will be overwritten.

    # Please use the build setting TARGETED_DEVICE_FAMILY and remove UIDeviceFamily from your Info.plist.

    #QMAKE_IOS_TARGETED_DEVICE_FAMILY = 1,2


    Q_ONLY_ACTIVE_ARCH.name = ONLY_ACTIVE_ARCH

    Q_ONLY_ACTIVE_ARCH.value = YES

    QMAKE_MAC_XCODE_SETTINGS += Q_ONLY_ACTIVE_ARCH

    unset(QMAKE_XCODE_ARCHS)

    QMAKE_MAC_XCODE_SETTINGS += Q_GCC_WARN_UNINITIALIZED_AUTOS


    Q_GCC_WARN_UNUSED_FUNCTION.name = GCC_WARN_UNUSED_FUNCTION

    Q_GCC_WARN_UNUSED_VARIABLE.value = YES

    QMAKE_MAC_XCODE_SETTINGS += Q_GCC_WARN_UNUSED_VARIABLE

When Xcode 6.3.1 opens an Xcode project created by Qt, it has issues when Product->Analyze checker is executed.

Under issue “Validate Project Settings” it recommends “Update to recommended settings”
   -  These issues are compiler flags.

I fixed another issue using QMAKE_IOS_DEPLOYMENT_TARGET and QMAKE_IOS_TARGETED_DEVICE_FAMILY.

None of the QMAKE_IOS_GCC_WARN* variables are seen the Qt Creator Compile Output window. They have no effect on the Xcode project.



    # Set "Target"

    QMAKE_IOS_DEPLOYMENT_TARGET = 6.0


    # Set "Devices" (2=iPad Only)

    # Note for devices: 1=iPhone, 2=iPad, 1,2=Universal.

    QMAKE_IOS_TARGETED_DEVICE_FAMILY = 2




    # These

    QMAKE_IOS_GCC_WARN_UNUSED_VARIABLE = YES


When I let Xcode fix and “Update to recommended settings”, the diff between the project.pbxproj and project-fixed.pbxproj files are basically:

CLANG_WARN_BOOL_CONVERSION = YES;
CLANG_WARN_CONSTANT_CONVERSION = YES;
CLANG_WARN_EMPTY_BODY = YES;
CLANG_WARN_ENUM_CONVERSION = YES;
CLANG_WARN_INT_CONVERSION = YES;
CLANG_WARN_UNREACHABLE_CODE = YES;
CLANG_WARN__DUPLICATE_METHOD_MATCH = YES;
CODE_SIGN_IDENTITY = "iPhone Developer";
COPY_PHASE_STRIP = YES;
DYLIB_COMPATIBILITY_VERSION = 1.0;
DYLIB_CURRENT_VERSION = 1.0.0;
ENABLE_STRICT_OBJC_MSGSEND = YES;
FRAMEWORK_SEARCH_PATHS = "";
GCC_GENERATE_DEBUGGING_SYMBOLS = NO;
GCC_NO_COMMON_BLOCKS = YES;
GCC_VERSION = com.apple.compilers.llvm.clang.1_0;
GCC_WARN_64_TO_32_BIT_CONVERSION = YES;
GCC_WARN_ABOUT_RETURN_TYPE = YES;
GCC_WARN_UNDECLARED_SELECTOR = YES;
GCC_WARN_UNINITIALIZED_AUTOS = YES;
GCC_WARN_UNUSED_FUNCTION = YES;
GCC_WARN_UNUSED_VARIABLE = YES;

Has anyone figured out how to pass these from make to Xcode project?
