编译 libeXosip2说明

浏览编译说明 libeXosip2-4.1.0/help/INSTALL.linux

Common Install process for linux/UNIX.

1: compile/install libosip first.

  $> tar -xvzf libosip2-x.x.x.tar.gz
  $> CFLAGS="-I/usr/local/include/" ../configure
  $> make
  $> make install      (as root...)

2: compile/install eXosip

  $> tar -xvzf libeXosip2-x.x.x.tar.gz
  $> CFLAGS="-I/usr/local/include/" ../configure
  $> make
  $> make install      (as root...)

所以编译libeXosip2-4.1.0 ,需要先编译 libosip2-4.1.0 （保持版本的一致）

第一步，编译libosip2

编译libosip2-4.1.0
编译：

$ ./configure --prefix=$PWD/_install & make & make install
$ ./configure --prefix=$PWD/_install --host=arm-none-linux-gnueabi  & make & make install

顺利产生以下文件
libosip2-4.1.0/_install/lib/
|-libosip2.a
|-libosip2.so
|-libosipparser2.a
|-libosipparser2.so

第二步，编译libeXosip2

编译 libeXosip2-4.1.0
但是使用 ./configure –prefix=$PWD/_install & make & make install
编译阶段报错
/usr/local/lib/libosipparser2.so: could not read symbols: File in wrong format
collect2: ld returned 1 exit status
make: *** [libeXosip2.la] Error 1

显然是configure配置阶段就出现了配置不完整的情况。
网上的资料基本上只讲到把相关的文件拷贝到 /usr/local/ 目录下面；
比如
cp libosip2-3.0.1/src/osip2/.libs/libosip2.a /usr/lib
cp libosip2-3.0.1/src/osipparser2/.libs/libosipparser2.a /usr/lib

但是显然这是需要root权限的，所以希望在不影响其他用户的其他下，在自己的权限目录下进行编译。
则需要配置相关的目录。

./configure --prefix=$PWD/_install LDFLAGS="-L/home/zzy/project/wrtWgServerlib/debug/libosip2-4.1.0/_install/lib" \
LIBS="-losipparser2 -losip2" --host=x84_64-unknown-linux-gnu

配置成这样，虽然configure可以配置通过，但是仍然没有通过make；
报错依旧；
下面需要怎么样的配置呢，但是 configure help 的时候已经说到配置 LIBS 以及 LDFLAGS 了
没有讲到更多的配置方式，网上的资料也是少之又少；
编译动态库的时候仍然无法实现，所以屏蔽编译动态库后：

#
# build.sh
#
echo "BUILD libeXosip2-4.1.0"
./configure --prefix=$PWD/_install \
CC=gcc \
--host=x84_64-unknown-linux-gnu \
--disable-tools \
--disable-debug \
--disable-trace \
--disable-shared \
--enable-openssl \
--enable-static \
CFLAGS='-I/home/admin/project/demo/osip_demo/libosip2-4.1.0/_install/lib/include' \
LDFLAGS='-L/home/admin/project/demo/osip_demo/libosip2-4.1.0/_install/lib' \
LIBS='-losipparser2 -losip2' \
SIP_CFLAGS='-I/home/admin/project/demo/osip_demo/libosip2-4.1.0/_install/lib/include' \
OSIP_LIBS='-L/home/admin/project/demo/osip_demo/libosip2-4.1.0/_install/lib -losipparser2 -losip2'

如果配置嵌入式环境：
CC=arm-none-linux-gnueabi-gcc
–host=arm-none-linux-gnueabi

配置成功后可以生成：
libeXosip2-4.1.0/_install
|-include
|-lib
|-lib/libeXosip2.a
|-lib/libeXosip2.la
这是在屏蔽生成动态库的时候，如果需要生成动态库，估计依然报错；

生成动态库的方法了：
configure 的时候除了生成Makefile之外，还生成了libtool文件，需要修改libtool文件：

# Compile-time system search path for libraries.
sys_lib_search_path_spec="/home/zzy/project/demo/osip_demo/libosip2-4.1.0/_install/lib \
/usr/lib/gcc/x86_64-linux-gnu/4.4.7 \
/usr/lib/x86_64-linux-gnu \
/usr/lib \
/lib/x86_64-linux-gnu /lib "

# Run-time system search path for libraries.
sys_lib_dlsearch_path_spec="/home/zzy/project/demo/osip_demo/libosip2-4.1.0/_install/lib \
/lib \
/usr/lib \
/usr/lib/i386-linux-gnu/mesa \
/lib/i386-linux-gnu /usr/lib/i386-linux-gnu \
/lib/i686-linux-gnu /usr/lib/i686-linux-gnu \
/usr/local/lib /lib/x86_64-linux-gnu \
/usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/mesa \
/lib32 \
/usr/lib32 "

在sys_lib_search_path_spec和sys_lib_dlsearch_path_spec中添加lib的搜索路径;
运行编译脚本

# build.sh
echo "BUILD libeXosip2-4.1.0"

./configure --prefix=$PWD/_install \
CC=gcc \
--host=x84_64-unknown-linux-gnu \
--disable-tools \
--disable-debug \
--disable-trace \
--enable-openssl \
--enable-static \
CFLAGS='-I/home/admin/project/demo/osip_demo/libosip2-4.1.0/_install/lib/include' \
LDFLAGS='-L/home/admin/project/demo/osip_demo/libosip2-4.1.0/_install/lib' \
LIBS='-losipparser2 -losip2' \
SIP_CFLAGS='-I/home/admin/project/demo/osip_demo/libosip2-4.1.0/_install/lib/include' \
OSIP_LIBS='-L/home/admin/project/demo/osip_demo/libosip2-4.1.0/_install/lib -losipparser2 -losip2'

使用libeXosip2自带的样例测试注册流程

libeXosip2-4.1.0/tools/sip_reg.c
编译：

# build.sh
gcc -O2 -I/home/admin/project/demo/osip_demo/libosip2-4.1.0/_install/include \
    -L/home/admin/project/demo/osip_demo/libosip2-4.1.0/_install/lib \
    -I/home/admin/project/demo/osip_demo/libeXosip2-4.1.0/_install/include \
    -L/home/admin/project/demo/osip_demo/libeXosip2-4.1.0/_install/lib \
    sip_reg.c \
    -o sipreg \
    -leXosip2 -losip2 -losipparser2 -lpthread

运行：

# reg.sh 
./sipreg  \
-r sip:192.168.1.22:5060 \
-u sip:01001010101@192.168.1.22 \
-c sip:01001010101@192.168.1.22:5060 \
-U 01001010101 \
-P 01001010101  \
-p 5061 \
-e 1800 \
-d

启动服务器(192.168.1.22)后，运行客户端测试样例：

$ sh build.sh
$ sh reg.sh   
username: 01001010101
password: [removed]01001010101
eXosip_add_authentication_info success
(143)eXosip_register_build_initial_register 2*expiry=3600
---------------
fromuser = sip:01001010101@192.168.1.22
   proxy = sip:192.168.1.22:5060
 contact = sip:01001010101@192.168.1.22:5060
---------------
(169)type=0
registrered successfully

修改注册服务器地址为192.168.1.66 则会注册失败(无代理服务器)

$ sh build.sh
$ sh reg.sh   
username: 01001010101
password: [removed]01001010101
eXosip_add_authentication_info success
(143)eXosip_register_build_initial_register 2*expiry=3600
---------------
fromuser = sip:01001010101@192.168.1.66
   proxy = sip:192.168.1.66:5060
 contact = sip:01001010101@192.168.1.66:5060
---------------
(169)type=1
(175)(nil), Registration failed!

运行程序之后需要添加动态库的搜索路径
分别在libosip2-4.1.0/_install/lib目录，
libeXosip2-4.1.0/_install/lib目录下运行：
export LD_LIBRARY_PATH=`pwd`:$LD_LIBRARY_PATH

以上程序是修改过的sip_reg.c，也仅仅是删除掉一些多余的不影响的宏定义；

样例中使用的是基于oSIP开源库的SIP代理服务器PartySIP

添加注册成功后进行呼出

switch (event->type) {

        regparam.auth = 1;
break;
case EXOSIP_CALL_PROCEEDING:
printf("Processing\n"); // 对方(01001010102)正在进行处理
break;
case EXOSIP_CALL_RINGING:
printf("Ringing\n");// 对方(01001010102)振铃
break;
default:
break;
}

嗯，是的，需要两次调用eXosip_call_build_initial_invite
