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 commands are the easiest way can avoid above errors on CentOS 7 - note that you should run below in root.
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 -f /usr/lib64/libstdc++.so.6 ln -s /usr/lib64/libstdc++.so.6.0.26 /usr/lib64/libstdc++.so.6
If you want to uninstall Anaconda
conda install anaconda-clean
You may also need to remove anaconda on your root directory.
