使用Xcode5.1错误为iOS编译libogg

Question

环境:MacOSX10.9.2，Xcode 5.1。构建shell脚本如下所示：

#!/bin/sh

set -xe

VERSION="1.3.1"
DESTDIR="libogg-built"

#ARCHS="i386 x86_64 armv7 armv7s arm64"

rm -rf $DESTDIR
mkdir $DESTDIR

if [ ! -e "libogg-$VERSION.zip" ]; then
    curl -LO http://downloads.xiph.org/releases/ogg/libogg-$VERSION.zip
fi

unzip -oq libogg-$VERSION.zip
cd libogg-$VERSION


./configure

for ARCH in $ARCHS;
do
    mkdir -p ../$DESTDIR/$ARCH

    IOSMV="-miphoneos-version-min=4.3"
    case $ARCH in
    arm*)
        if [ $ARCH == "arm64" ]; then
            IOSMV="-miphoneos-version-min=7.0"
        fi
        PATH=`xcodebuild -version -sdk iphoneos PlatformPath`"/Developer/usr/bin:$PATH" \
        SDK=`xcodebuild -version -sdk iphoneos Path` \
        CC="xcrun --sdk iphoneos clang -arch $ARCH $IOSMV --sysroot=$SDK -isystem $SDK/usr/include" \
        CXX="xcrun --sdk iphoneos clang++ -arch $ARCH $IOSMV --sysroot=$SDK -isystem $SDK/usr/include" \
        LDFLAGS="-Wl,-syslibroot,$SDK" \
        ./configure \
        #--host=arm-apple-darwin \
        --prefix=../$DESTDIR/$ARCH
        ;;
    *)
        PATH=`xcodebuild -version -sdk iphonesimulator PlatformPath`"/Developer/usr/bin:$PATH" \
        #SDK=`xcodebuild -version -sdk iphonesimulator Path` \
        CC="xcrun --sdk iphonesimulator clang -arch $ARCH $IOSMV" \
        CXX="xcrun --sdk iphonesimulator clang++ -arch $ARCH $IOSMV" \
        ./configure \
        #--host=x86_64-apple-darwin \
        --prefix=../$DESTDIR/$ARCH
        ;;
    esac

    make
    make install
    make clean
done

cd ..
mkdir -p ${DESTDIR}/universal/lib

INPUT=""
for ARCH in $ARCHS; 
do
    INPUT="$INPUT $DESTDIR/$ARCH/lib/libogg.a"
done
lipo -create $INPUT -output $DESTDIR/universal/lib/libogg.a

但终端记录显示：

+ VERSION=1.3.1
+ DESTDIR=libogg-built
+ ARCHS=i386
+ rm -rf libogg-built
+ mkdir libogg-built
+ '[' '!' -e libogg-1.3.1.zip ']'
+ unzip -oq libogg-1.3.1.zip
+ cd libogg-1.3.1
+ ./configure
+ for ARCH in '$ARCHS'
+ mkdir -p ../libogg-built/i386
+ IOSMV=-miphoneos-version-min=4.3
+ case $ARCH in
++ xcodebuild -version -sdk iphonesimulator PlatformPath
+ PATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin:/opt/local/bin:/opt/local/sbin:/Users/Smeegol/.rbenv/shims:/Users/Smeegol/.rbenv/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
+ CC='xcrun --sdk iphonesimulator clang -arch i386 -miphoneos-version-min=4.3'
+ CXX='xcrun --sdk iphonesimulator clang++ -arch i386 -miphoneos-version-min=4.3'
+ ./configure
+ --prefix=../libogg-built/i386
./build-libogg2.sh: line 55: --prefix=../libogg-built/i386: No such file or directory

为什么是"--prefix=../libogg-built/i386: No such file or directory"？它已经被创建了。

更新的：新的和正确的shell脚本如下所示：

#!/bin/sh

set -xe

VERSION="1.3.1"
DESTDIR="libogg-built"

ARCHS="i386 x86_64 armv7 armv7s arm64"

rm -rf $DESTDIR
mkdir $DESTDIR

if [ ! -e "libogg-$VERSION.zip" ]; then
    curl -LO http://downloads.xiph.org/releases/ogg/libogg-$VERSION.zip
fi

unzip -oq libogg-$VERSION.zip
cd libogg-$VERSION


./configure

for ARCH in $ARCHS;
do
    mkdir -p ../$DESTDIR/$ARCH

    IOSMV="-miphoneos-version-min=4.3"
    case $ARCH in
    arm*)
        if [ $ARCH == "arm64" ]; then
            IOSMV="-miphoneos-version-min=7.0"
        fi
        PATH=`xcodebuild -version -sdk iphoneos PlatformPath`"/Developer/usr/bin:$PATH" \

        CXX="xcrun --sdk iphoneos clang++ -arch $ARCH $IOSMV --sysroot=$SDK -isystem $SDK/usr/include" \
        LDFLAGS="-Wl,-syslibroot,$SDK" \
        ./configure \
        --host=arm-apple-darwin \
        --prefix=../$DESTDIR/$ARCH
        ;;
    *)
        PATH=`xcodebuild -version -sdk iphonesimulator PlatformPath`"/Developer/usr/bin:$PATH" \
        CC="xcrun --sdk iphonesimulator clang -arch $ARCH $IOSMV" \
        CXX="xcrun --sdk iphonesimulator clang++ -arch $ARCH $IOSMV" \
        ./configure \
        --prefix=../$DESTDIR/$ARCH
        ;;
    esac

    make
    make install
    make clean
done

cd ..
mkdir -p $DESTDIR/universal/lib

INPUT=""
for ARCH in $ARCHS; 
do
    INPUT="$INPUT $DESTDIR/$ARCH/lib/libogg.a"
done
lipo -create $INPUT -output $DESTDIR/universal/lib/libogg.a

Answer 1

--prefix=../$DESTDIR/$ARCH

您可能对相对路径有问题。通常使用安装根目录的完整路径(如果不是更简单的话)会更好。

你可以尝试的一件事，如果这是问题所在，就是扩大路径，然后再试一次.例如：

export INSTALL_ROOT=$(cd ../libogg-built/i386; pwd)
./configure ...
...
--prefix="${INSTALL_ROOT}"

如果这有帮助，请告诉我们！配置脚本可能非常挑剔。

Update：尽管如此，在第一次点击提交之后，我才意识到它要简单得多：

    CXX="xcrun --sdk iphonesimulator clang++ -arch $ARCH $IOSMV" \
    ./configure \
    #--host=x86_64-apple-darwin \
    --prefix=../$DESTDIR/$ARCH
    ;;

..。当您在多行上继续执行命令时，不能有一个从行到尾的注释.只要移除#--host=x86_64-apple-darwin \，您就应该被设置。

Answer 2

您可以参考https://github.com/firstfan/libspeex-iOS

它用最新的SDK和最新的speex代码编译OK。
