编译live555的时候遇到了这个问题，前面的编译没有问题，是在链接的时候出现的，在网上搜索说是缺少 libstdc++ 库。于是，安装之
#sudo apt-get install libstdc++-dev
shawn@ubuntu:~/work/live555-master_1$ sudo apt-get install libstdc++-dev
[sudo] password for shawn:

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
选择一个安装
#sudo apt-get install libstdc++-8-dev
安装完成，问题没有得到解决。。。。。。。。。。。

可能这次报的错和上次不一样吧，意思是在编译选项上加上-fPIC ,于是在 COMPILE_OPTS 和 CONSOLE_LINK_OPTS 都加上 -fPIC ，
#./genMakefile linux
#make
编译成功！
