Xcode5之后多了对arm64的支持，所以之前编译的库也要适时的更新下，而且gcc和g++在arm平台暂时还木有对arm64进行支持（这个是个人推断）所以编译采用clang和clang++，当然Mac平台采用这两个编译器编译c和c++是要比gcc和g++好的，因为前面两个是apple当初为了Mac平台专门开发的编译器。
下面进入正题，相较于之前的在终端模式下，逐行敲命令，我们可选择更为灵活和便利的shell脚本。
1.编译libamr
#!/bin/sh
# opencore_amr.sh
#
#
# Created by cxjwin on 13-10-17.
#
# 打开调试回响模式,并配置环境
set -xe
# /Applications/Xcode.app/Contents/Developer
DEVELOPER=`xcode-select -print-path`
# 我们编译到桌面的opencore_amr_ios文件夹
DEST=${HOME}/Desktop/opencore_amr_ios
# 我们需要编译的平台,一共是5个,arm64是64位amr处理器
ARCHS="i386 x86_64 armv7 armv7s arm64"
# 一共是两种类型的静态库
LIBS="libopencore-amrnb.a libopencore-amrwb.a"
# Note that AMR-NB is for narrow band http://en.wikipedia.org/wiki/Adaptive_Multi-Rate_audio_codec
# for AMR-WB encoding, refer to http://sourceforge.net/projects/opencore-amr/files/vo-amrwbenc/
# or AMR Codecs as Shared Libraries http://www.penguin.cz/~utx/amr
# 每一个平台对应一个文件夹
for arch in $ARCHS;
do
mkdir -p $DEST/$arch
done
./configure
# libamr是C++库所以只要设置CXX变量就可以了，采用clang++编译
for arch in $ARCHS;
do
make clean
# 现版Xcode支持SDK4.3以上
IOSMV="-miphoneos-version-min=4.3"
case $arch in
arm*)
echo "Building opencore-amr for iPhoneOS $arch ****************"
# amr64只支持iOS7
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` \
CXX="xcrun --sdk iphoneos clang++ -arch $arch $IOSMV --sysroot=$SDK -isystem $SDK/usr/include" \
LDFLAGS="-Wl,-syslibroot,$SDK" \
./configure \
--host=arm-apple-darwin \
--prefix=$DEST/$arch \
--disable-shared

*)

make install
done
make clean
# lipo打包合并静态库
echo "Merge into universal binary."
for i in $LIBS;
do
input=""
for arch in $ARCHS; do
input="$input $DEST/$arch/lib/$i"
done
lipo -create $input -output $DEST/$i
done
PS:完整的库文件在我的github里面clone后运行opencore_amr.sh即可
2.编译speex库
这个相对复杂些，因为speex还以来libogg库，所以这里我们先要编译libogg库。
2.1.编译libogg
shell脚本其实也是大同小异
#!/bin/sh
# build_ogg_ios.sh
#
#
# Created by cxjwin on 15-4-19.
#
set -xe
DEVELOPER=`xcode-select -print-path`
ROOTDIR=`pwd`
DEST=${ROOTDIR}/../speexLibrary/libogg-1.3.2
ARCHS="i386 x86_64 armv7 armv7s arm64"
LIBS="libogg.a"
for arch in $ARCHS;
do
mkdir -p $DEST/$arch
done
for arch in $ARCHS;
do
make clean
IOSMV="-miphoneos-version-min=5.0"
case $arch in
arm*)
echo "Building opencore-amr for iPhoneOS $arch ****************"
if [ $arch == "arm64" ]
then
IOSMV="-miphoneos-version-min=7.0"
fi

make clean

for i in $LIBS;
do

do

done
lipo -create $input -output $DEST/$i
done
PS:完整的库文件在我的github里面clone后,找到libogg-1.3.2文件夹运行里面build_ogg_ios.sh即可
2.2编译speexdsp

因为speex是依赖libogg库的所以一定要注意编译顺序。speex-1.2rc2以后speexdsp-1.2rc3从speex里面抽离了出来,所以需要单独编译.
当然这里编译的过程中，自己也学习了下shell脚本。Xcode本身就支持shell脚本，Xcode编译的时候我们就可以把工程的.a文件一并打包成一个，以便于模拟器和真机同时引用，当然这又是另外一个主题了。
