Hey, During some routine Debian cleanups, I found that configure fails if you enable mysql support but use libmariadb-dev, without MySQL compatibility symlinks (eg libmysqlclient.so).
The attached patch makes configure try -lmysqlclient, and fallback to - lmariadb if that fails. Thanks, Jordi -- Jordi Mallach <[email protected]>
Author: Jordi Mallach <[email protected]> Date: Tue Aug 18 2026 Forwarded: not-yet Fall back to -lmariadb when -lmysqlclient is unavailable. Debian's libmariadb-dev package ships libmariadb.so/libmariadbclient.so, which export mysql_real_connect and the rest of the mysqlclient ABI, but not libmysqlclient.so itself; only the transitional libmariadb-dev-compat package provides that symlink. Since mailutils Build-Depends on libmariadb-dev, probe for -lmariadb too so --with-mysql keeps working without needing the compat package.
