When I run biftool on CentOS 7, faced following errors:


/pub/production/_lib/bif/biftool: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /pub/production/_lib/bif/biftool)
/pub/production/_lib/bif/biftool: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by /pub/production/_lib/bif/biftool)
/pub/production/_lib/bif/biftool: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /pub/production/_lib/bif/biftool)


Below is the easiest way can avoid above errors on CentOS 7

wget https://repo.anaconda.com/archive/Anaconda3-2019.07-Linux-x86_64.sh
sh Anaconda3-2019.07-Linux-x86_64.sh


cd
cp anaconda3/lib/libstdc++.so.6.0.26 /usr/lib64



rm /usr/lib64/libstdc++.so.6
ln -s /usr/lib64/libstdc++.so.6.0.26 /usr/lib64/libstdc++.so.6
