编译生成静态库

• Build iOS(按照ijkplayer文档执行)

git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-ios
cd ijkplayer-ios
git checkout -B latest k0.8.0
./init-ios.sh
cd ios
./compile-ffmpeg.sh clean
./compile-ffmpeg.sh all

• 创建一个新项目,并将ijkplayer-ios/ios/IJKMediaPlayer目录下的IJKMediaPlayer.xcodeproj拉进项目中.

• 选择Target为IJKMediaFramework,然后点击Edit Scheme按钮

• 设置Run -> info -> Build Configuration 的值为Release

• 分别选择模拟器和真机,进行一次Bunild.在Products文件夹下就可以看到生成的.framework

• 右击IJKMediaFramework.framework,选择Show in Finder,可以找到适用于模拟器和真机的两个静态库

• lipo -info查看信息

cd Release-iphonesimulator/IJKMediaFramework.framework
lipo -info IJKMediaFramework
//输出Architectures in the fat file: IJKMediaFramework are: i386 x86_64
cd Release-iphoneos/IJKMediaFramework.framework
lipo -info IJKMediaFramework
//输出Architectures in the fat file: IJKMediaFramework are: armv7 arm64 

• 最后在Product目录下执行合并的命令,你就可以得到一个即支持模拟器又支持真机的静态库了

lipo -create Release-iphonesimulator/IJKMediaFramework.framework/IJKMediaFramework Release-iphoneos/IJKMediaFramework.framework/IJKMediaFramework -output IJKMediaFramework

• 将生成的IJKMediaFramework文件,复制到Release-iphoneos/IJKMediaFramework.framework目录下,替换掉原来的IJKMediaFramework.
• 至此完整的IJKMediaFramework.framework已经生成,可以直接放到项目中使用了.

我遇到的问题

Undefined symbols for architecture x86_64:

解决方法:添加 libstdc++.tbd
