如何构建一个包含构建 Mac Catalyst 应用程序所需架构的胖框架?
苹果引入了一个(未记录的?)新目标:x86_64-apple-ios13.0-macabi
如何构建此目标取决于您的框架构建环境。
1)XC框架
如果您的框架是 Xcode 项目:
- 在 Xcode 中选择目标
- 选择“常规”选项卡
- Under "Deployment Info", tick the "Mac" checkbox:
- build
2) 外部构建
如果您在 Xcode 之外构建框架,例如一个 C lib,而不是为 x86_64 和 iphonesimulator 构建,而是为新目标 x86_64-apple-ios13.0-macabi 和 macosx 构建。
使用 make 的 C 库示例:
MIN_IOS_VERSION="10.0"
LIB_NAME= "theNameOfYourLib"
# The build function
build()
{
ARCH=$1
TARGET=$2
HOST=$3
SDK=$4
SDK_PATH=`xcrun -sdk ${SDK} --show-sdk-path`
export PREFIX=build/${ARCH}
export CFLAGS="-arch ${ARCH} -isysroot ${SDK_PATH} -miphoneos-version-min=${MIN_IOS_VERSION} -std=c99 -target ${TARGET}"
export LDFLAGS="-arch ${ARCH}"
export CC="$(xcrun --sdk ${SDK} -f clang) -arch ${ARCH} -isysroot ${SDK_PATH}"
PKG_CONFIG_ALLOW_CROSS=1 PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig ./configure --host=${HOST} --prefix=$PREFIX
make
make install
}
# Build for all required architectures
build "armv7" "armv7-apple-ios" "arm-apple-darwin" "iphoneos" # MIN_IOS_VERSION must be one of arm7 supported ones to. Else remove this line.
build "arm64" "aarch64-apple-ios" "arm-apple-darwin" "iphoneos"
# build "x86_64" "x86_64-apple-ios" "x86_64-apple-darwin" "iphonesimulator" #obsolete due to x86_64-apple-ios13.0-macabi
build "x86_64" "x86_64-apple-ios13.0-macabi" "x86_64-apple-darwin" "macosx"
build "i386" "i386-apple-ios" "i386-apple-darwin" "iphonesimulator" # same as arm7: MIN_IOS_VERSION must be one of arm7 supported ones.
# Now find all the artefacts created above (e.g. build/arm64/lib/${LIB_NAME}.a, build/x86_64/lib/${LIB_NAME}.a ...) and merge them together to a fat lib using lipo
OUTPUT_DIR="fatLib"
lipo -create -output $OUTPUT_DIR/lib/${LIB_NAME}.a build/x86_64/lib/${LIB_NAME}.a build/arm64/lib/${LIB_NAME}.a build/armv7/lib/${LIB_NAME}.a build/i386/lib/${LIB_NAME}.a
# You may also need the header files
cp -R build/armv7/include/* $OUTPUT_DIR/include/
Note:您必须/不能添加切片x86_64-apple-ios
and x86_64-apple-ios13.0-macabi
到胖库。两者都是 x86_64。仅使用其中一个x86_64-apple-ios13.0-macabi
