Hi, please check if you have this file
/scratch/lead/ext_libs/support/libstdc++.so.6 (md5: b6532193067692c716a81da2194d733e). It should work if the newer lib file is at present. It will be loaded from lead folder first rather than use the system’s old one. If it still doesn’t work, you may try to add this line in your env or .bashrc:
export LD_LIBRARY_PATH=/scratch/lead/ext_libs/support:$LD_LIBRARY_PATH to see if it works.
