Running Issues

If you are encountering issues like (especially on CentOS-7)

[user1@node1 7-zip]$ ./7zz
./7zz: /lib64/libstdc++.so.6: version CXXABI_1.3.8' not found (required by ./7zz) 
./7zz: /lib64/libstdc++.so.6: versionCXXABI_1.3.9' not found (required by ./7zz)

You need a more recent GNU Compilers rather than the default one used in CentOS-7 which is very old, you may want to compile more recent GNU. Remember to complete the $LD_LIBRARY_PATH and $PATH something like this

export PATH=$PATH:/usr/local/gcc-6.5.0/bin
export LD_LIBRARY_PATH= $LD_LIBRARY_PATH:/usr/local/gcc-6.5.0/lib64
