我需要帮助。我尝试使用SRTP 2.1.0和OpenSSL 1.1.0构建JRTPLIB 3.1.1，但在尝试生成JRTPLIB时出现链接器错误。
依赖关系：
Debian 9（也在Ubuntu 16.04 LTS上试过） JRTPLIB v.3_1_11（来自git +更改） JTHREAD v.1_3_3（来自git） LIBSRTP v.2_1_0（按标签） LIBSSL v.1_1_0稳定（按分支）
来源变化： JRTPLIB v.3_1_11（来自git）：将srtp更改为srtp2;链接到lib源档案：https://drive.google.com/drive/folders/0B_Q0HXvHrCzabVpsSUp0TXNka1U?usp=sharing
Cmake设置（图片cmake_JRTPLIB.JPG）：https://drive.google.com/drive/folders/0B_Q0HXvHrCzabVpsSUp0TXNka1U?usp=sharing
构建
1）的OpenSSL： 从源代码构建并尝试在虚拟机上通过sudo apt-get install libssl1.1 libssl-dev安装libssl1.1和libssl-dev 2）libSRTP： $。/ configure --enable-debug-logging --enable-log-stdout --enable-openssl
3）JTHREAD：使用cmake构建
4）JRTPLIB：Cmake配置 - 请参阅图像cmake_JRTPLIB.JPG $化妆
