# Extra CCARGS can be: -DHAS_LDAP -DHAS_MYSQL -I/usr/include/mysql
# Extra AUXLIBS can be: -lldap -llber -lmysqlclient -lz

# Build with SASL support
SASLARGS="-DUSE_SASL_AUTH -I/usr/include/sasl -DUSE_CYRUS_SASL"
SASLLIBS="-L/usr/lib${LIBDIRSUFFIX}/sasl2 -lsasl2"
# Note: this enables both server SASL types (Cyrus and Dovecot) as well as
# client SASL with Cyrus.  See SASL_README if you wish to customize this.
# For example, you might not wish to link against Cyrus SASL if not using
# client SASL.  For Dovecot (server) SASL only, comment SASLLIBS, and set:
# SASLARGS="-DUSE_SASL_AUTH"

# Build with TLS support, see TLS_README
TLSARGS="-DUSE_TLS"
TLSLIBS="-lssl -lcrypto"

# Build with LDAP client support, see LDAP_README
LDAPARGS="-DHAS_LDAP"
# MySQL database support, see MYSQL_README
MYSQLARGS="-I/usr/include/mysql -DHAS_MYSQL"
# PCRE (perl-compatible regular expressions) support, see PCRE_README
PCREARGS="-DHAS_PCRE $( pcre-config --cflags )"
# SQLite3 database support, see SQLITE_README
SQLITEARGS="-DHAS_SQLITE"
# Finally, DBARGS lumps it all together:
DBARGS="$LDAPARGS $MYSQLARGS $PCREARGS $SQLITEARGS"

### ADDITIONAL MAP TYPE PLUGINS
#
# Those who have installed other map types not included in Slackware could
# add support as follows:
#
#  * AUXLIBS_CDB for CDB support, see /usr/doc/postfix/readme/CDB_README
#  * AUXLIBS_LMDB for LMDB support, see /usr/doc/postfix/readme/LMDB_README
#  * AUXLIBS_PGSQL for PostgreSQL support, see /usr/doc/postfix/readme/PGSQL_README
#  * AUXLIBS_SDBM for SDBM support, see /usr/doc/postfix/readme/SDBM_README
#
# Note that each of these additional map types will require additions to
# the CCARGS variable.  Typically this would be done by adding what is
# needed to $DBARGS.

### CHANGING BUILT-IN DOCUMENTATION PATH SETTINGS
#
# If we try to use postfix-$VERSION in any of these paths, we'll get a compile
# failure: "error: too many decimal points in number"
# So we're pretty much forced to leave things as postfix expects them.
