Hm…
But we still want to build for iOS. There isn't really a problem with that in
Xcode 4.2/Lion/iOS5.0/CMake2.8-6 in my experience.
We now have this as "toolchain" (but actually, just included):
...
IF ( RT_IOS)
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")
SET (CMAKE_OSX_SYSROOT "${SDKROOT}")
SET (CMAKE_OSX_ARCHITECTURES "$(ARCHS_UNIVERSAL_IPHONE_OS)") # Either
"$(ARCHS_UNIVERSAL_IPHONE_OS)" or "arm6" "arm7"
SET (CMAKE_C_COMPILER "${DEVROOT}/usr/bin/gcc")
SET (CMAKE_CXX_COMPILER "${DEVROOT}/usr/bin/g++")
# SET (CMAKE_FIND_ROOT_PATH "${DEVELOPMENT_ROOT}"
"/opt/iphone-${RT_SDKVER}/" "/usr/local/iphone-${RT_SDKVER}/")
SET (CMAKE_FIND_ROOT_PATH_MODE_PROGRAM BOTH)
SET (CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET (CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
ENDIF()
…
So you propose we skip specifying the compiler altogether? Remove:
SET (CMAKE_C_COMPILER "${DEVROOT}/usr/bin/gcc")
SET (CMAKE_CXX_COMPILER "${DEVROOT}/usr/bin/g++")
Wasn't sure if this worked anyway.
I see now Xcode is just using the default compiler (Apple LLVM Compiler (3.0))
instead of LLVM GCC 3.0.
Thanks,
Daniel
