Hi, by default, MonetDB's configure script behaves as if called with, e.g., --enable-monetdb5=auto and --enable-sql=auto, (see also `configure --help`) i.e., it will (try to) build client (mclient), server (MonetDB5) and SQL front-end (MonetDB/SQL); but will opt to (silently) skip any of them if some build requirements are not fulfilled. See the summary that it produced at the end of your configure run. If you use --enable-monetdb5[=yes] & --enable-sql configure will still (try to) build all components, but now will fail with an error if it cannot do so, i.e., in case some build requirements are not fulflled.

Thanks for the reference Martin.

So if I get it correctly, I have to use "--enable-sql" in configure if I want to use SQL as the query language with "mclient", and not MAL (but ultimately SQL is converted to or represented as MAL internally).

Hi The kernel of MonetDB supports a lower level language, called MAL, as well. The SQL code depends on that one.

Hi,

Is it necessary to give --enable-sql option at the time of compilation if one wants to use SQL as the query language or does it have some other connotation? The reason for asking is, if I give --enable-sql option, the configure script compels me to give --enable-monetdb5 option too.

I am not sure how these options make difference internally to the MonetDB server, since as per the MonetDB website SQL is the de facto language for querying DBs and that is what is used by MonetDB as well.

Can someone please enlighten?

Thanks. Medha
