ios - 使用XCode 5为iOS编译Opus 1.1-rc2

转载作者：行者123 更新时间：2023-12-01 16:45:30

我正在尝试使用适用于iOS的ARM NEON优化来编译Opus 1.1-rc2。

这是我正在使用的配置:

export CC="xcrun -sdk iphoneos clang -arch armv7"
export CCAS="xcrun -sdk iphoneos clang -arch armv7 -no-integrated-as"
./configure --enable-fixed-point \
            --disable-doc \
            --disable-extra-programs \
            --with-sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk \
            --host=arm-apple-darwin

如果我使用 --disable-asm，那么所有内容都会编译良好:)但是我确实想要ARM NEON优化，所以我不想放这个标志。麻烦来了:

没有 -no-integrated-as，我得到:
