    Hi, I am trying to run an executable that needs libmysqlclient.so but I get the following error
    Code:
    error while loading shared libraries: libmysqlclient.so.20: cannot open shared object file: No such file or directory
    
    I have tried to google and figure out how to get it but I haven't had any luck with that. Anyone who has any idea? Thanks.

    what's the full error message ? version of centmin mod used ? and mariadb version ?

    Output for following commands
    Code (Text):
    mysqladmin ver
    rpm -ql MariaDB-compat | grep '.so'
    updatedb
    locate libmysqlclient.so

    I figured this out as it seems like one needs MySQL 7. I don't think MariaDB has libmysqlclient.so.20 (version 20).

    But anyways here's the output for following commands

    Code:
    mysqladmin  Ver 9.1 Distrib 10.0.27-MariaDB, for Linux on x86_64
    Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.

    No output for updatedb

    Code:
    /usr/lib64/libmysqlclient.so
    /usr/lib64/libmysqlclient.so.15
    /usr/lib64/libmysqlclient.so.15.0.0
    /usr/lib64/libmysqlclient.so.16
    /usr/lib64/libmysqlclient.so.16.0.0
    /usr/lib64/libmysqlclient.so.18
    /usr/lib64/libmysqlclient.so.18.0.0
    /usr/lib64/mysql/libmysqlclient.so
    
    Latest centminmod (stable I think) is being used. And full error message is simply that in op, that libmysqlclient.so.20 is missing.

    .20 is for Oracle MySQL 5.7

    .18 is used by MariaDB 10.1 and Percona MySQL 5.7
    .16 is used by MariaDB 10.0 and 5.5

    Probably get him to code for .16 minimum
