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

[Edward Sutton]

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_CLANG_WARN_BOOL_CONVERSION = YES

    QMAKE_IOS_CLANG_WARN_CONSTANT_CONVERSION = YES

    QMAKE_IOS_CLANG_WARN_EMPTY_BODY = YES

    QMAKE_IOS_CLANG_WARN_ENUM_CONVERSION = YES

    QMAKE_IOS_CLANG_WARN_INT_CONVERSION = YES

    QMAKE_IOS_CLANG_WARN_UNREACHABLE_CODE = YES

    QMAKE_IOS_CLANG_WARN__DUPLICATE_METHOD_MATCH = YES


    QMAKE_IOS_GCC_WARN_64_TO_32_BIT_CONVERSION = YES

    QMAKE_IOS_GCC_WARN_ABOUT_RETURN_TYPE = YES

    QMAKE_IOS_GCC_WARN_UNDECLARED_SELECTOR = YES

    QMAKE_IOS_GCC_WARN_UNINITIALIZED_AUTOS = YES

    QMAKE_IOS_GCC_WARN_UNUSED_FUNCTION = YES

    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?
