Hi, I am trying to install MonetDB5 11.2.0 (The version of MonetDB is not an official MonetDB release. This version includes an RDF frontend that is used to parse RDF datasets and load them in MonetDB.). I get the following error when I run the make command: miguel@miguel-VirtualBox:~/Downloads/MonetDB$ sudo make make all-recursive make[1]: Entering directory '/home/miguel/Downloads/MonetDB' Making
