如何构建包含Mac Catalyst的Fat Framework? [英] How to build a Fat Framework that includes Mac Catalyst?

问题描述

如何构建一个胖框架，其中包括构建Mac Catalyst应用所需的架构?

How does one build a fat framework that includes the architectures necessary to build to Mac Catalyst apps?

推荐答案

Apple引入了(未记录?)新目标:x86_64-apple-ios13.0-macabi

Apple has introduced a (undocumented?) new target: x86_64-apple-ios13.0-macabi

如何为此目标进行构建取决于您的框架构建环境.

How to build for this target depends on your frameworks build environment.

1)XCFramework

如果您的框架是Xcode项目:

In case your framework is an Xcode project:

• 在Xcode中选择目标
• 选择常规"标签
• 在部署信息"下，选中"Mac"复选框:
• 构建

• Select the target in Xcode
• Select the "General" tab
• Under "Deployment Info", tick the "Mac" checkbox:
• build

2)外部版本

如果您要在Xcode之外构建框架，例如C库，而不是针对x86_64& iphonesimulator，为新目标x86_64-apple-ios-13.0-macabi& macosx.

In case you are building your framework outside Xcode, e.g. a C lib, instead of building for x86_64 & iphonesimulator, build for the new target x86_64-apple-ios13.0-macabi & macosx.

使用make的C Lib示例:

Example for C Lib using make:

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/

注意:您必须/不能将x86_64-apple-ios和x86_64-apple-ios13.0-macabi的切片添加到fat lib中.两者都是x86_64. x86_64-apple-ios13.0-macabi仅使用一个.

---

Note: You must/can not add slices for x86_64-apple-ios and x86_64-apple-ios13.0-macabito the fat lib. Both are x86_64. Use only the one for x86_64-apple-ios13.0-macabi.
