本文详细介绍如何下载、编译PJSIP库，并解决编译过程中的常见错误，如权限问题和缺少libasound-dev库。同时提供在不同Linux发行版下的解决方案，包括Ubuntu和CentOS。

下载pjsip库并解压
```
$ tar -jxvf pjproject-2.9.tar.bz2
```

编译

$ cd pjproject-2.9
$ ./configure
$ make dep
$ make

编译成功后生成静态库：

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

如果报错sudo: ./configure: command not found，赋权即可：

chmod 777 configure

chmod 755 ./configure

如果make过程中报错：alsa/asoundlib.h: No such file or directory，或者拨号时报以下错误

12:39:55.753 os_core_unix.c !pjlib 2.1 for POSIX initialized 
12:39:55.754 sip_endpoint.c .Creating endpoint instance... 
12:39:55.754 pjlib .select() I/O Queue created (0x93f1a80) 
12:39:55.754 sip_endpoint.c .Module "mod-msg-print" registered 
12:39:55.754 sip_transport. .Transport manager created. 
12:39:55.754 pjsua_core.c .PJSUA state changed: NULL --> CREATED

12:39:55.770 pjsua_aud.c .Error retrieving default audio device parameters: Invalid audio device (PJMEDIA_EAUD_INVDEV) [status=420004] Exception: Object: Lib, operation=set_current_sound_devices(), error=Invalid audio device (PJMEDIA_EAUD_INVDEV)

这是因为没有安装libasound-dev库，安装即可

```
apt-get install libasound2-dev
```
而在centos系统下yum install找不到libasound-dev，这时需要下面指令安装。
```
yum install alsa-lib-devel
```
安装后reboot系统，重新编译即可。
安装：若想将库安装到系统中，执行
```
make install
```
安装后pjlib生成的库文件位于/usr/local/lib

为了减少链接多个库文件，pjsip工程会生成一个配置文件libpjproject.pc
位于路径/usr/local/lib/pkgconfig/libpjproject.pc下
