编译speex(i386、armv6、armv7、armv7s)方法
编译speex(i386、armv6、armv7、armv7s)方法
本文借鉴：http://www.cocoachina.com/bbs/read.php?tid=114755&keyword=speex
桌面上建立speexLibrary文件夹，将下载的libogg-1.3.0、speex-1.2rc1放入；
一、编译ogg:
1.ogg-i386的库
通过如下命令进入/Users/wangping/Desktop/speexLibrary/libogg-1.3.0目录，因为configure在此目录下：
1)cd Desktop/
2)ls
3)cd speexLibrary/
4)ls
5)cd libogg-1.3.0/
直接用：cd Desktop/speexLibrary/libogg-1.3.0/
编译ogg-i386库：
6）./configure -prefix=/Users/wangping/Desktop/speexLibrary/libogg-1.3.0/i386 -host=i386-apple-darwin -build=x86_64-apple-darwin11.3.0 CC="/Applications/Xcode.app/Contents/Developer/usr/llvm-gcc-4.2/bin/llvm-gcc-4.2 -std=c99 -arch i386 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk/"
7）make (如提示make命令无效，则xcode -> preferences ->downloads -> command line tools安装)
make install
make clean (一定要clean，不然后面编译的都是第一次的编译的内容)
2、ogg-armv6的库 －－不使用（无必要）
xcode4.6默认不能编译armv6(可以编译方法：http://blog.csdn.net/lmxxf/article/details/8770286)
./configure -prefix=/Users/wangping/Desktop/speexLibrary/libogg-1.3.0/armv6 -host=armv6-apple-darwin -build=x86_64-apple-darwin11.3.0 CC="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/llvm-gcc-4.2 -std=c99 -arch armv6 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/"
make
make install
make clean
3、ogg-armv7的库
./configure -prefix=/Users/wangping/Desktop/speexLibrary/libogg-1.3.0/armv7 -host=armv7-apple-darwin -build=x86_64-apple-darwin11.3.0 CC="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/llvm-gcc-4.2 -std=c99 -arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/"
4、ogg－armv7s的库
4、./configure -prefix=/Users/wangping/Desktop/speexLibrary/libogg-1.3.0/armv7s -host=armv7s-apple-darwin -build=x86_64-apple-darwin11.3.0 CC="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/llvm-gcc-4.2 -std=c99 -arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/"
make
make install
make clean
二、接着编译speex库：
关掉终端，重新打开
首先进入文件夹：cd Desktop/speexLibrary/speex-1.2rc1/
1.speex-i386的库
./configure -prefix=/Users/wangping/Desktop/speexLibrary/speex-1.2rc1/i386 -host=i386-apple-darwin -disable-shared -enable-static -disable-oggtest -disable-fixed-point -enable-float-api -build=x86_64-apple-darwin11.3.0 -with-ogg=/Users/wangping/Desktop/speexLibrary/libogg-1.3.0/i386 CC="/Applications/Xcode.app/Contents/Developer/usr/llvm-gcc-4.2/bin/llvm-gcc-4.2 -std=c99 -arch i386 -isysroot/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk/"
make
make install
make clean
2.speex-armv6的库 －－不使用（无必要）
./configure -prefix=/Users/wangping/Desktop/speexLibrary/speex-1.2rc1/armv6 -host=armv6-apple-darwin -disable-shared -enable-static -disable-oggtest -enable-fixed-point -disable-float-api -build=x86_64-apple-darwin11.3.0 -with-ogg=/Users/wangping/Desktop/speexLibrary/libogg-1.3.0/armv6 CC="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/llvm-gcc-4.2 -std=c99 -arch armv6 -isysroot/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/"
make
make install
make clean
3.speex-armv7的库
./configure -prefix=/Users/wangping/Desktop/speexLibrary/speex-1.2rc1/armv7 -host=armv7-apple-darwin -disable-shared -enable-static -disable-oggtest -enable-fixed-point -disable-float-api -build=x86_64-apple-darwin11.3.0 -with-ogg=/Users/wangping/Desktop/speexLibrary/libogg-1.3.0/armv7 CC="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/llvm-gcc-4.2 -std=c99 -arch armv7 -isysroot/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/"
4、speex-armv7s的库
./configure -prefix=/Users/wangping/Desktop/speexLibrary/speex-1.2rc1/armv7s -host=armv7s-apple-darwin -disable-shared -enable-static -disable-oggtest -enable-fixed-point -disable-float-api -build=x86_64-apple-darwin11.3.0 -with-ogg=/Users/wangping/Desktop/speexLibrary/libogg-1.3.0/armv7s CC="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/llvm-gcc-4.2 -std=c99 -arch armv7s -isysroot/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/"
make
make install
make clean
最后合并静态库，进入相应文件夹:，终端键入：
1）合并libogg
在libogg-1.3.0下建立OutPut_A文件夹：
cd Desktop/speexLibrary/libogg-1.3.0/
不带arm6:
lipo -create i386/lib/libogg.a armv7/lib/libogg.a armv7s/lib/libogg.a -output libogg.a
2）合并speex的2个库
在speex-1.2rc1下建立OutPut_A文件夹：
cd Desktop/speexLibrary/speex-1.2rc1/
不带arm6:
lipo -create i386/lib/libspeex.a armv7/lib/libspeex.a armv7s/lib/libspeex.a -output OutPut_A/libspeex.a
lipo -create i386/lib/libspeexdsp.a armv7/lib/libspeexdsp.a armv7s/lib/libspeexdsp.a -output OutPut_A/libspeexdsp.a
好了，这里应该已经编译完成了。如果合并静态库不成功，那么请检查上述步骤（我当时就是忘了make clean，导致编译的都是i386的.a文件）.你可以lipo -info xxx.a文件，后面会显示库内文件使用的平台信息，正常显示为i386,armv6,armv7那么就成功了。当然打包好的库我也一并上传了，方便大家下载。
cd Desktop/speexLibrary/libogg-1.3.0/OutPut_A
查看编译好的.a的架构：
都拷贝到桌面上来，然后
cd Desktop
lipo -info libogg.a
lipo -info libspeex.a
lipo -info libspeexdsp.a
为：i386 armv7 (cputype (12) cpusubtype (11))
另：在本身的文件夹里看：
bogon:speex-1.2rc1 wangping$ cd OutPut_A
bogon:OutPut_A wangping$ lipo -info libspeex.a
Architectures in the fat file: libspeex.a are: i386 armv6 armv7
bogon:OutPut_A wangping$ lipo -info libspeexdsp.a
Architectures in the fat file: libspeexdsp.a are: i386 armv6 armv7
