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/pj
vi 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
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/Developer
ARCH="-arch i386" CFLAGS="-O2 -m64 -mios-simulator-version-min=8.0" LDFLAGS="-O2 -m64 -mios-simulator-version-min=8.0" ./configure-iphone
make 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-iphone
make dep && make clean && make
armv7s直接执行以下命令：
ARCH='-arch armv7s' ./configure-iphone
make dep && make clean && make
arm64执行以下命令
ARCH='-arch arm64' ./configure-iphone
make 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/armv7
make dep && make clean && make
make install
armv7s
sudo ARCH='-arch armv7s' ./configure-iphone --prefix=/Users/eleccomm/Downloads/pjproject-2.6/sip/armv7s
make dep && make clean && make
make install
arm64
sudo ARCH='-arch arm64' ./configure-iphone --prefix=/Users/eleccomm/Downloads/pjproject-2.6/sip/arm64
make dep && make clean && make
make 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 ${DEVPATH}" fi
if [ "$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/x86
make dep && make clean && make
make 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/x64
make dep && make clean && make
make install
4. 合并静态库
mkdir sip/all
mkdir sip/all/lib
cd /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
