[CMake] iOS Archiving (Xcode 4.2, Lion, CMake2.8-6)

[Daniel Dekkers]

Hi,

Has anyone managed to perform a successful iOS Archiving pass yet?

Our apps run on the simulator (both iPhone (5.0) and iPad (5.0)) and on the actual devices iPhone 3GS (5.0.1) and iPad2 (5.0.1), but archiving always gives a link error:

Ld /Users/danieldekkers/Library/Developer/Xcode/DerivedData/All-fgyaqwkvsryjkhbiepprnmdcager/ArchiveIntermediates/Discs/InstallationBuildProductsLocation/Application/Discs.app/Discs normal armv7

This is a problem, because you have to archive an ipa file, AdHoc or AppStore to ship your application.

These are our IOS specific settings at the moment, lots of trial-and-error, but at least they work on the simulator and attached devices:

IF( RT_IOS )
	# "Toolchain" settings can (for the time being) just be included...
	SET (CMAKE_SYSTEM_NAME Generic)
	SET (CMAKE_SYSTEM_VERSION 1)
	SET (CMAKE_SYSTEM_PROCESSOR arm)

	SET (RT_SDKVER "5.0" CACHE PATH "iOS SDK version" )
	SET (DEVROOT "/Developer/Platforms/iPhoneOS.platform/Developer")
	SET (SDKROOT "${DEVROOT}/SDKs/iPhoneOS${RT_SDKVER}.sdk")
	IF( EXISTS ${SDKROOT} )
		SET (CMAKE_OSX_SYSROOT "${SDKROOT}")
	ELSE()
		MESSAGE( "Warning, iOS SDK path not found: " ${SDKROOT})
	ENDIF()
	SET (CMAKE_OSX_ARCHITECTURES "$(ARCHS_UNIVERSAL_IPHONE_OS)") # Either "$(ARCHS_UNIVERSAL_IPHONE_OS)" or "arm6" "arm7"

	# SET (CMAKE_C_COMPILER "${DEVROOT}/usr/bin/gcc")      # Can be removed, just let Xcode choose the default.
	# SET (CMAKE_CXX_COMPILER "${DEVROOT}/usr/bin/g++")    # Can be removed, just let Xcode choose the default.

	SET (CMAKE_FIND_ROOT_PATH "${DEVELOPMENT_ROOT}" "${SDKROOT}" "${DEVROOT}")
	SET (CMAKE_FIND_ROOT_PATH_MODE_PROGRAM BOTH)
	SET (CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
	SET (CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

	SET( RT_DEPLOYMENT_TARGET "4.3" CACHE STRING "minimum required SDK" )

	SET( GCC_INPUT_FILETYPE "Objective-C++" )
	SET( CMAKE_CXX_FLAGS "-x objective-c++ -mno-thumb" )

	# For iOS builds this is needed for the app to initiate the UIApplication delegate instance...
	SET( CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -ObjC" )

	# Look in the correct build directories when linking the app to the RenderTools library...
	SET( CMAKE_XCODE_EFFECTIVE_PLATFORMS "-iphoneos;-iphonesimulator" )
ENDIF()

Just wondering if someone is following the same path.

Thanks,

Daniel
