編譯speex(i386、armv6、armv7、armv7s)方法
本文借鑑：http://www.cocoachina.com/bbs/read.php?tid=114755&keyword=speex
桌面上建立speexLibrary文件夾，將下載的libogg-1.3.0、speex-1.2rc1放入；
一、編譯ogg:
1.ogg-i386的庫
通過如下命令進入/Users/wangping/Desktop/speexLibrary/libogg-1.3.0目錄，因爲configure在此目錄下：
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/
編譯ogg-i386庫：
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命令無效，則xcode -> preferences ->downloads -> command line tools安裝)
make install
make clean (一定要clean，不然後面編譯的都是第一次的編譯的內容)
2、ogg-armv6的庫 －－不使用（無必要）
xcode4.6默認不能編譯armv6(可以編譯方法：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的庫
./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的庫
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、接着編譯speex庫：
關掉終端，重新打開
首先進入文件夾：cd Desktop/speexLibrary/speex-1.2rc1/
1.speex-i386的庫
./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的庫 －－不使用（無必要）
./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的庫
./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的庫
./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
最後合併靜態庫，進入相應文件夾:，終端鍵入：
1）合併libogg
在libogg-1.3.0下建立OutPut_A文件夾：
cd Desktop/speexLibrary/libogg-1.3.0/
不帶arm6:
lipo -create i386/lib/libogg.a armv7/lib/libogg.a armv7s/lib/libogg.a -output libogg.a
2）合併speex的2個庫
在speex-1.2rc1下建立OutPut_A文件夾：
cd Desktop/speexLibrary/speex-1.2rc1/
不帶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，這裏應該已經編譯完成了。如果合併靜態庫不成功，那麼請檢查上述步驟（我當時就是忘了make clean，導致編譯的都是i386的.a文件）.你可以lipo -info xxx.a文件，後面會顯示庫內文件使用的平臺信息，正常顯示爲i386,armv6,armv7那麼就成功了。當然打包好的庫我也一併上傳了，方便大家下載。
cd Desktop/speexLibrary/libogg-1.3.0/OutPut_A
查看編譯好的.a的架構：
都拷貝到桌面上來，然後
cd Desktop
lipo -info libogg.a
lipo -info libspeex.a
lipo -info libspeexdsp.a
爲：i386 armv7 (cputype (12) cpusubtype (11))
另：在本身的文件夾裏看：
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
