rlm_sql_unixodbc ?

[Jim Rice]

I thought I had followed the FR installation instructions and was surprised 
that something might have been missing.
How can I know which dependencies are missing?  (Which packages to install?)

I had already installed mysql-connector-odbc before finding 
rlm_sql_unixodbc.
There were several new library files added, including 
/usr/lib/libodbc.so.1.0.0  But -lodbc not so much.
