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
