iOS静态库的编译
ios ffmpeg集成speex
OS X Lion, make/configure issue, trying to compile 64-bit libFLAC/libFLAC++(需越过高山)
speex部分:
一:官网下载最新的稳定版speex (目前是1.2.0)
speex 1.2.0 下载地址
二:配置configure文件
查看帮助
$ ./configure --help
在命令行输入
arm64
$ ./configure -prefix=/Users/lj/Desktop/speex-1.2.0/speexlib -host=armv64-apple-darwin --disable-shared --enable-static --disable-float-api --disable-binaries CC="xcrun -sdk iphoneos clang -mios-version-min=8.0 -fembed-bitcode -arch arm64"
armv7s
$ ./configure -prefix=/Users/lj/Desktop/speex-1.2.0/armv7s -host=armv7s-apple-darwin --disable-shared --enable-static --disable-float-api --disable-binaries CC="xcrun -sdk iphoneos clang -mios-version-min=8.0 -fembed-bitcode -arch armv7s"armv7
参数:
-prefix:编译后内容存放地
-build:在什么宿主机上面编译(系统会自动识别,可以省略)
-host:交叉编译产生的项目要放在什么系统上运行(必填)
--enable-static:生成静态库
CC="xcrun -sdk iphoneos clang -mios-version-min=8.0 -fembed-bitcode -arch arm64" 使用xcode指定的编译器,最低版本是8,处理器架构为arm64
三:编译
$ make && make install四:遇到的问题
1.在make命令是很多下面的报错
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: archive member: .libs/libspeex.a(exc_10_32_table.o) cputype (16777223) does not match previous archive members cputype (16777228) (all members must match)
解决办法:
OS X Lion, make/configure issue, trying to compile 64-bit libFLAC/libFLAC++(需越过高山)
配置文件时加上:
--disable-debug--disable-asm-optimizations --enable-sse
2.也是在make时报错
clang: warning: argument unused during compilation: '-msse' [-Wunused-command-line-argument]

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~SpeexDSP部分:
一:前序
从1.2rc2版本中，speex就将非压缩和解压缩部分放在了SpeexDSP中，从speexz中分离出来了,
打算编译,结果armv7,armv7s都编译好了,唯独arm64编译不过,因为什么arm架构处理器扩展结构(NEON)的问题一直编译不过,没法, 打算撸源码了
二:准备工作
1.下载SpeexDSP 版本1.2rc3 下载地址:https://www.speex.org/downloads/
2.从下载包里面去掉源码之外的东西,这个版本下,我就只留下了include和libspeesdsp两个文件夹
三:开撸
1.将文件拖进工程,编译报错:如下之类的地方报错
#ifndef FLOATING_POINT
#error You now need to define either FIXED_POINT or FLOATING_POINT
#endif
#if defined (ARM4_ASM) || defined(ARM5E_ASM) || defined(BFIN_ASM)
#error I suppose you can have a [ARM4/ARM5E/Blackfin] that has float instructions?
#endif
#ifdef FIXED_POINT_DEBUG
#error "Don't you think enabling fixed-point is a good thing to do if you want to debug that?"
#endif
在工程中build-setting->preprocessor macros下修改如下,便能修复这个问题
2.运行,报错#include "speex/speex_preprocessor.h" file not found
删除speex/就可以了,这个错有很多,耐心改,
3.运行,还报错,提示有好多的main.o
去libspeexdsp文件夹下面删除四个测试文件
4.这下好了,成功运行;
下面部分是自己的测试代码,有点儿乱,但是可以看更新日志中的过程

看我这么辛苦,给个start呗
