在arm-linux编译osip-exosip2(LHL).docx

在arm-linux编译osip，exosip21 osip，exosip2简介Osip2是一个开放源代码的sip协议栈，是使用C语言写的协议栈，它具有短小简洁的特点，专注于sip底层解析使得它的效率比较高。但缺点也很明显，首先就是可用性差，没有很好的api封装，使得上层应用在调用协议栈时很破碎；其次，只做到了事务（transaction）层次的协议过程解析，缺少呼叫（call）、会议（session）、对话（dialog）等过程的解析，这也增加了使用的难度；再次，缺少线程并发处理的机制，使得它的处理能力有限。 eXosip是Osip2的一个扩展协议集，它部分封装了Osip2协议栈，使得它更容易被使用。eXosip增加了call、dialog、registration、subscription等过程的解析，使得实用性更强。但是eXosip局限于UA的实现，使得它用于registrar、sip server等应用时极其不容易。另外，它并没有增加线程并发处理的机制。2 下载： a) /gnu/osip/ b) /releases/exosip/ 3 配置编译环境交叉编译环境库路径拷贝到“/home/lhluser/tools/arm-bcm2708”，运行下面命令，配置环境变量。复制下面语句到命令行#export CC=/home/lhluser/tools/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin/arm-bcm2708hardfp-linux-gnueabi-gcc4 编译osip2a) 将libosip2-3.6.0.tar.gz解压到“/home/lhluser/LHL/libosip2-3.6.0”b) #cd /home/lhluser/LHL/libosip2-3.6.0c) #mkdir osiparmlib 建立工作路径d) #cd osiparmlib 进入工作路径e) #chmod +x ./configure 修改文件为可执行查看configure配置文件：$././configure -help osip2_configure_help.txtf) #././configure -prefix=/home/lhluser/LHL/armlib -target=arm-linux -host=arm-linux -enable-static=yes -enable-shared=nog) #makeh) #make install完成后，生成的libosip2.so.7.2.0、libosip2.a、libosipparser2.so.7.2.0和libosipparser2.a库文件在“/home/lhluser/LHL/armlib/lib”目录下，include文件在“/home/lhluser/LHL/armlib/include”下5 编译eXosipa) 将libeXosip2-3.6.0.tar.gz解压到“/home/lhluser/LHL/libeXosip2-3.6.0b) #cd /home/lhluser/LHL/libeXosip2-3.6.0c) #cp ./armlib/lib/* /usr/lib/d) #cp -r ./libosip2-3.6.0/osiparmlib/include/osipparser2 ./libeXosip2-3.6.0/include/osipparser2e) #cp -r ./libosip2-3.6.0/osiparmlib/include/osip2 ./libeXosip2-3.6.0/include/osip2f) #mkdir eXosiparmlib 建立工作路径g) #cd eXosiparmlib 进入工作路径h) #chmod +x ./configure 修改文件为可执行查看configure配置文件：$././configure -help eXosip2_configure_help.txti) #././configure -prefix=/home/lhluser/LHL/armlib -target=arm-linux -host=arm-linux -enable-static=yes -enable-shared=noj) #make cleank) #makel) #make install完成后，configure文件中指示生成路径为“/home/lhluser/LHL/armlib”，生成的libeXosip2.so.7.2.0和libeXosip2.a库文件在“/home/lhluser/LHL/armlib/lib”目录下，include文件在“/home/lhluser/LHL/armlib /include”下6 验证示例程序： 6.1 创建qt工程“文件”“新建文件或项目”“QT Gui 应用”名称：eXosip2_init创建路径：/home/lhluser/LHL/eXosip2_init使用构建套件：ARM_Kit进入“项目”“构建和运行”“构建设置”将“Release”和“Debug”中的影子工程（Shadow build）去掉6.2 复制编译好的库和头文件到该工程路径下$ cp -r /usr/local/include /home/lhluser/LHL/eXosip2_init/eXosip2_init/include$ cp -r /usr/local/lib /home/lhluser/LHL/eXosip2_init/eXosip2_init/lib建立调用库路径()和头文件路径()6.3 添加代码修改工程文件“eXosip2_”，添加头部和库路径说明如下：INCLUDEPATH += ./includeINCLUDEPATH += ./include/eXosip2INCLUDEPATH += ./include/osip2INCLUDEPATH += ./include/osipparser2INCLUDEPATH += .l/include/osipparser2/headersQMAKE_LIBDIR += ./libLIBS += -losip2LIBS += -losipparser2LIBS += -leXosip2在文件“main.cpp”的头部添加头部说明extern C#include 在文件”main.cpp”的“int main(int argc, char *argv)”中添加如下代码，用于测试编译库是否正确。 int i;
