MonetDB "server requires unknown hash"

I built MonetDB from source. After I unpack the tarball, I followed these steps:

mkdir build
cd build
cmake ..
make
sudo make install

I was able to install monetdbd and mclient, and they are both at version 11.39.7. However, when I follow the tutorial to create a new database, mclient cannot authenticate even the default user (monetdb):

$> mclient -u monetdb -d imdb
password: (I entered 'monetdb')
server requires unknown hash 'SHA512'

What does this "server requires unknown hash 'SHA512'" mean? How can I resolve this?

p.s. I also tried to change the configuration so that it only uses MD5, but I then get a similar message: "server requires unknown hash 'MD5'".

Solution

  • You need to install the "openssl" library on your system. Which OS are you using?

    You need the development packages: openssl-devel on RPM-based systems, libssl-dev on Debian like systems. Look also in debian/control inside the tar ball to see what is required

    FYI, since the Oct2020, MonetDB/e (i.e. MonetDB embedded) doesn't require openssl, so MonetDB has dropped this requirement. However, when you use the MonetDB client-server, you need this library.
