1. 环境

在 Ubuntu 16.4.5 TLS 版本中编译和测试通过。

下载最新的源代码需要git，若没有安装git可以使用下面命令进行安装：

sudo apt-get install git -y

2. 编译及安装

2.1 下载源码

git clone https://github.com/cisco/libsrtp.git

2.2 进入源码目录

cd libsrtp

2.3 配置

Build done. Please run 'make runtest' to run self tests.

2.5 测试编译结果

使用下面命令测试编译结果（编译成功时最后有提示运行该命令）

make runtest

执行结果，如下所示：

cgs@ubuntu:~/libsrtp$ make runtest

2.6 安装

安装命令如下（特别需要注意前面的 sudo，否则会出现安装错误）：

sudo make install

执行结果，如下所示：

cgs@ubuntu:~/libsrtp$ sudo make install
[sudo] password for cgs: 
/usr/bin/install -c -d /usr/local/include/srtp2
/usr/bin/install -c -d /usr/local/lib
cp ./include/srtp.h /usr/local/include/srtp2
cp ./crypto/include/cipher.h /usr/local/include/srtp2
cp ./crypto/include/auth.h /usr/local/include/srtp2
cp ./crypto/include/crypto_types.h /usr/local/include/srtp2
if [ -f libsrtp2.a ]; then cp libsrtp2.a /usr/local/lib/; fi
if [ -f libsrtp2.dll.a ]; then cp libsrtp2.dll.a /usr/local/lib/; fi
if [ -f libsrtp2.so.1 ]; then \
	/usr/bin/install -c -d /usr/local/lib; \
	cp libsrtp2.so.1 /usr/local/lib/; \
	cp libsrtp2.so /usr/local/lib/; \
	if [ -n "1" ]; then \
		ln -sfn libsrtp2.so.1 /usr/local/lib/libsrtp2.so; \
	fi; \
fi
/usr/bin/install -c -d /usr/local/lib/pkgconfig
cp ./libsrtp2.pc /usr/local/lib/pkgconfig/

至此，编译安装完成。

3. 测试

首先，进入libsrtp的测试文件目录

cd test

然后，执行测试命令如下

./rtpw_test.sh

执行结果，如下所示：

cgs@ubuntu:~/libsrtp$ cd test
cgs@ubuntu:~/libsrtp/test$ ./rtpw_test.sh

4. 常见问题

Q：执行安装命令 make install ，出现安装失败，错误信息如下：

cgs@ubuntu:~/libsrtp$ make install
/usr/bin/install -c -d /usr/local/include/srtp2
/usr/bin/install: cannot change permissions of ‘/usr/local/include/srtp2’: No such file or directory
Makefile:268: recipe for target 'install' failed
make: *** [install] Error 1

A：由于安装需要向 /usr/bin、/usr/local等目录拷贝文件，需要su权限，所以需要调整安装命令为 sudo make install ，即命令前面增加 sudo ，并根据提示输入su密码即可安装成功。
