iOS之PJSIP的编译与简单使用

公司要做网络通话及网络视频，初试，希望各位多多指点，有做过的希望联系一下我，有些不懂得地方还望指教。

首先先谈一下PJSIP的编译，及在编译中我所遇到的问题。

1.去官网下载http://www.pjsip.org（pjproject-2.6.tar.bz2），并解压

2.在pjlib/include/pj/目录下，建立一个config_site.h的文件

cd /Users/eleccomm/Downloads/pjproject-2.6/pjlib/include/pjvi config_site.h

根据官方说明文档，我们的文件内容定义如下：

#define PJ_CONFIG_IPHONE 1#include <pj/config_site_sample.h>

对于小白可能不太熟悉怎样终端插入，按i开始插入内容，输入完成后Esc退出插入，输入:wq回车即可退出编辑状态，然后起还到主目录下，即包含pjlib、pjlib-util、pjmedia、pjnath的目录下

3.编译静态库

i386，依次执行下面三行：

export DEVPATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/DeveloperARCH="-arch i386" CFLAGS="-O2 -m64 -mios-simulator-version-min=8.0" LDFLAGS="-O2 -m64 -mios-simulator-version-min=8.0" ./configure-iphonemake dep && make clean && make

成功后，模拟器编译好的静态库会存在于

• pjlib/lib
• pjlib-util/lib
• pjmedia/lib
• pjnath/lib
• pjsip/lib
• third_party/lib

armv7，关闭刚刚的终端，重新回到主目录，依次执行以下命令：

ARCH='-arch armv7' ./configure-iphonemake dep && make clean && make

armv7s，直接执行以下命令：

ARCH='-arch armv7s' ./configure-iphonemake dep && make clean && make

arm64，执行以下命令：

ARCH='-arch arm64' ./configure-iphonemake dep && make clean && make

————————————————————————————————————————————————

也可以这样编译静态库

回到主目录，创建一个文件夹

mkdir sip

编译静态库

armv7

sudo ARCH='-arch armv7' ./configure-iphone  --prefix=/Users/eleccomm/Downloads/pjproject-2.6/sip/armv7make dep && make clean && makemake install

armv7s

sudo ARCH='-arch armv7s' ./configure-iphone  --prefix=/Users/eleccomm/Downloads/pjproject-2.6/sip/armv7smake dep && make clean && makemake install

arm64

sudo ARCH='-arch arm64' ./configure-iphone  --prefix=/Users/eleccomm/Downloads/pjproject-2.6/sip/arm64make dep && make clean && makemake install

编译模拟器库的时候需要先在主目录下的configure-iphone中添加几行代码

vim configure-iphone 

在第一个if前面添加上如是代码：

if [ "$ARCH" = "-arch x86_64" ]; then  DEVPATH="/Applications/XCode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer"  echo "$F: Simulator 64bit, using ${DEVPATH}"fiif [ "$ARCH" = "-arch i386" ]; then  DEVPATH="/Applications/XCode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer"  echo "$F: Simulator 32bit, using ${DEVPATH}"fi

i386

sudo ARCH="-arch i386" CFLAGS="-O2 -m64 -mios-simulator-version-min=7.0" LDFLAGS="-O2 -m64 -mios-simulator-version-min=7.0" ./configure-iphone --prefix=/Users/eleccomm/Downloads/pjproject-2.6/sip/x86make dep && make clean && makemake install

x64

sudo ARCH="-arch x86_64" CFLAGS="-O2 -m64 -mios-simulator-version-min=7.0" LDFLAGS="-O2 -m64 -mios-simulator-version-min=7.0" ./configure-iphone --prefix=/Users/eleccomm/Downloads/pjproject-2.6/sip/x64make dep && make clean && makemake install

4.合并静态库

mkdir sip/allmkdir sip/all/libcd /Users/eleccomm/Downloads/pjproject-2.6/sip

合并静态库

将arm64中的include文件夹copy到all目录下

5.将编译好的库导入到项目中去

配置Header Search Paths ——> $(PROJECT_DIR)/phone/all/include；

Other Linker Flags: -ObjC;

Preprocessor Macros: PJ_AUTOCONF=1

在Build Phases中的Link Binary With Libraries中添加Framework：AudioToolbox、AVFoundation
