如何构建Cocoa Touch Framework for i386和x86_64架构？ [英] How to build Cocoa Touch Framework for i386 and x86_64 architecture?

问题描述

在构建Cocoa Touch框架（Swift或Object-C）并将其添加到另一个项目作为嵌入二进制文件后，我得到以下错误消息，当我尝试生成

After building a Cocoa Touch framework (Swift or Object-C) and adding it to another project as "Embedded Binaries" I get the following error message when I try to build

missing required architecture i386
...
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

i386 更改为架构构建设置...

Following various existing answers and extended research I already added i386 to the Architectures build settings …

但这似乎没有效果。当我检查使用

However this doesn't seem to have an effect. When I check using

lipo -info TesterFrameworkObjC

我只能得到

Architectures in the fat file: TesterFrameworkObjC are: armv7 arm64

... i386（和x86_64）不应该出现在这里吗？我缺少什么？

… shouldn't i386 (and x86_64) appear here as well? What am I missing?

（我为iOS 8.2使用Xcode 6.2 +版本）

(I am using Xcode 6.2 + building for iOS 8.2)

使用此版本 build script 我可以为Swift版本的框架构建缺少的体系结构。

Using a version of this build script I am able to build the missing architectures for the Swift version of the framework.

但是当我添加这个框架到我的应用程序，我仍然得到错误

However when I add this framework to my app and build I still get errors

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$__TtC20TesterFrameworkSwift18TestFrameworkSwift", referenced from:
  objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture x86_64

查找在模拟器的最终构建文件夹构建

Looking at the final build folder building for the simulator

Build/Products/Debug-iphoneos/TesterFrameworkSwift.framework/

我可以看到架构仍然缺失，虽然他们是框架的一部分（如图所示）。在构建应用程序时，如何确保我的框架的所有正确的架构构建都包含在内？

I can see that the architectures are still missing although they were part of the framework (as shown). How can I ensure all the right architecture builds of my framework are included when building the app?

查看所有的错误消息给我，它看起来像不是实际上有错误的产品/ archictures构建，但一步之后，有链接器没有使用正确的路径。不确定如何正确。

Looking at all the error messages to me it looks like the issue isn't actually to have the wrong products/archictures being built but one step later there the Linker isn't using the correct paths to them. Not sure how correct this.

推荐答案

这是相同的

This is the same problem that I had.

看起来这是一个Xcode，它是一个Xcode bug，我解决它通过添加一个构建脚本。
这将只是编译您的库与所有的架构，并 lipo 它到胖二进制映像。

Seems this is a Xcode bug, I workaround it by adding a build script. It will just compile your library with all architectures, and lipo it to fat binary image.

另请注意

查看构建模拟器的最终构建文件夹

Looking at the final build folder building for the simulator

/Products/Debug-iphoneos/TesterFrameworkSwift.framework /

Build/Products/Debug-iphoneos/TesterFrameworkSwift.framework/

您在iphone build文件夹中查找x86_64和i386映像， Debug-iphonesimulator / TesterFrameworkSwift.framework /

you are looking x86_64 and i386 images in iphone build folder, they should be in Debug-iphonesimulator/TesterFrameworkSwift.framework/

在脚本中还有一个递归问题，

Also there is a recursion issue in your script, I've corrected it.

UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal

if [ "true" == ${ALREADYINVOKED:-false} ]
then
echo "RECURSION: Detected, stopping"
else
export ALREADYINVOKED="true"

# Step 1. Build Device and Simulator versions
xcodebuild -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos  BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
xcodebuild -target "${PROJECT_NAME}" -configuration ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build

# Step 2. Copy the framework structure (from iphoneos build) to the universal folder
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework" "${UNIVERSAL_OUTPUTFOLDER}/"

# Step 3. Copy Swift modules (from iphonesimulator build) to the copied framework directory
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule/." "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule"

# Step 4. Create universal binary file using lipo and place the combined executable in the copied framework directory
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework/${PROJECT_NAME}"

# Step 5. Convenience step to copy the framework to the project's directory
cp -R "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework" "${PROJECT_DIR}"

# Step 6. Convenience step to open the project's directory in Finder
open "${PROJECT_DIR}"

6）点击cmd + B（Build Project）

6) Hit "cmd + B" (Build Project)

7）在 Finder中打开产品

>

8）向上导航1个目录（cmd +↑），您将看到Release-universal目录。

8) Navigate 1 directory up ("cmd + ↑"), and you will see "Release-universal" directory.

将会是您的fat / universal图书馆，您已准备好了！

There will be your "fat/universal" library, You are ready to go!
