Build cocos2d-x fat static library

from: http://www.nicnocquee.com/2016/01/20/build-cocos2d-x-fat-static-library.html

  1. Create a new empty project with targeting cocos2d-x version.
  2. Open project with Xcode to set build settings
  3. Go to <cocos2d-x_directory>/build
  4. Create a shell script file named buildstaticlib.sh as following: 
    #!/bin/bash

# This script is based on https://gist.github.com/rehos/7856163

if [ -z "$1" ]; then
  echo
  echo "usage: $0 <project.xcodeproj> [<scheme>]"
  echo
  exit
fi

if [ ! -d "$1" ]; then
  echo
  echo "Error: $1 does not exist"
  echo
  exit
fi

MY_PROJECT="$1"
MY_PROJECT_NAME=$(basename "$1")

if [ -z "$2" ]; then
	MY_SCHEME=${MY_PROJECT_NAME%.*}
else
	MY_SCHEME="$2"
fi

MY_STATIC_LIB="${MY_SCHEME}.a"
MY_BUILD_PATH=`mktemp -d -t "build"`
MY_SDK_VERSION=`xcrun --sdk iphoneos --show-sdk-version`

# armv7, armv7s
MY_ARM_BUILD_PATH="${MY_BUILD_PATH}/build-arm"
MY_CURRENT_BUILD_PATH="${MY_ARM_BUILD_PATH}"
xcodebuild -project "${MY_PROJECT}" -scheme "${MY_SCHEME}" -configuration 'Release' -sdk "iphoneos${MY_SDK_VERSION}" clean build ARCHS='armv7 armv7s' VALID_ARCHS='armv7 armv7s' IPHONEOS_DEPLOYMENT_TARGET='5.0' TARGET_BUILD_DIR="${MY_CURRENT_BUILD_PATH}" BUILT_PRODUCTS_DIR="${MY_CURRENT_BUILD_PATH}" OBJROOT="${MY_CURRENT_BUILD_PATH}" SYMROOT="${MY_CURRENT_BUILD_PATH}"

# arm64
MY_ARM64_BUILD_PATH="${MY_BUILD_PATH}/build-arm64"
MY_CURRENT_BUILD_PATH="${MY_ARM64_BUILD_PATH}"
xcodebuild -project "${MY_PROJECT}" -scheme "${MY_SCHEME}" -configuration 'Release' -sdk "iphoneos${MY_SDK_VERSION}" clean build ARCHS='arm64' VALID_ARCHS='arm64' IPHONEOS_DEPLOYMENT_TARGET='7.0' TARGET_BUILD_DIR="${MY_CURRENT_BUILD_PATH}" BUILT_PRODUCTS_DIR="${MY_CURRENT_BUILD_PATH}" OBJROOT="${MY_CURRENT_BUILD_PATH}" SYMROOT="${MY_CURRENT_BUILD_PATH}"

# i386
MY_I386_BUILD_PATH="${MY_BUILD_PATH}/build-i386"
MY_CURRENT_BUILD_PATH="${MY_I386_BUILD_PATH}"
xcodebuild -project "${MY_PROJECT}" -scheme "${MY_SCHEME}" -configuration 'Release' -sdk "iphonesimulator${MY_SDK_VERSION}" clean build ARCHS='i386' VALID_ARCHS='i386' IPHONEOS_DEPLOYMENT_TARGET='5.0' TARGET_BUILD_DIR="${MY_CURRENT_BUILD_PATH}" BUILT_PRODUCTS_DIR="${MY_CURRENT_BUILD_PATH}" OBJROOT="${MY_CURRENT_BUILD_PATH}" SYMROOT="${MY_CURRENT_BUILD_PATH}"

# x86_64
MY_X86_64_BUILD_PATH="${MY_BUILD_PATH}/build-x86_64"
MY_CURRENT_BUILD_PATH="${MY_X86_64_BUILD_PATH}"
xcodebuild -project "${MY_PROJECT}" -scheme "${MY_SCHEME}" -configuration 'Release' -sdk "iphonesimulator${MY_SDK_VERSION}" clean build ARCHS='x86_64' VALID_ARCHS='x86_64' IPHONEOS_DEPLOYMENT_TARGET='7.0' TARGET_BUILD_DIR="${MY_CURRENT_BUILD_PATH}" BUILT_PRODUCTS_DIR="${MY_CURRENT_BUILD_PATH}" OBJROOT="${MY_CURRENT_BUILD_PATH}" SYMROOT="${MY_CURRENT_BUILD_PATH}"

lipo -create "${MY_ARM_BUILD_PATH}/${MY_STATIC_LIB}" "${MY_ARM64_BUILD_PATH}/${MY_STATIC_LIB}" "${MY_I386_BUILD_PATH}/${MY_STATIC_LIB}" "${MY_X86_64_BUILD_PATH}/${MY_STATIC_LIB}" -output "${MY_STATIC_LIB}"

rm -rf "${MY_BUILD_PATH}"
  5. Run the script: ./buildstaticlib.sh cocos2d_libs.xcodeproj “libcocos2d iOS”

Now the fat static library is prepared. From now on, when creating a new project, follow below instructions:

  1. Remove “cocos2d” directory under the project and make a symbolic link to the “cocos2d” directory created for the fat static library.
  2. Remove dependency of “libcocos2d iOS” from “Build Phases” > “Target Dependencies”
  3. Remove “libcocos2d iOS.a” in “Build Phases” > “Link Binary With Libraries” and add newly built “libcocos2d iOS.a” using “Add Other…” button.
  4. Add “libcocos2d iOS.a” containing directory to “Build Settings” > “Library Search Path” to locate static library.
  5. Within Scheme of the main project, uncheck “Find Implicit Dependencies” of the Build tab.
  6. clean library targets such as “libcocos2d iOS” to make sure the fat static library is used in build phase.
