編譯live555的時候遇到了這個問題，前面的編譯沒有問題，是在鏈接的時候出現的，在網上搜索說是缺少 libstdc++ 庫。於是，安裝之

#sudo apt-get install libstdc++-dev

shawn@ubuntu:~/work/live555-master_1$ sudo apt-get install  libstdc++-dev

Package libstdc++-dev is a virtual package provided by:
  libstdc++-8-dev 8.2.0-1ubuntu2~18.04
  libstdc++-7-dev 7.3.0-27ubuntu1~18.04
  libstdc++-6-dev 6.4.0-17ubuntu1
  libstdc++-5-dev 5.5.0-12ubuntu1
  libstdc++-4.8-dev 4.8.5-4ubuntu8
  libc++-dev 6.0-2
You should explicitly select one to install.

E: Package ‘libstdc++-dev‘ has no installation candidate

選擇一個安裝

#sudo apt-get install libstdc++-8-dev

安裝完成，問題沒有得到解決。。。。。。。。。。。

可能這次報的錯和上次不一樣吧，意思是在編譯選項上加上-fPIC ,於是在 COMPILE_OPTS 和 CONSOLE_LINK_OPTS 都加上 -fPIC ，

#./genMakefile linux

#make

編譯成功！
