Hello, After installation I am getting the error: $ monetdbd create ~/monetdb/ monetdbd: error while loading shared libraries: libstream.so.3: cannot open shared object file: No such file or directory But the library (and the symlink to it) are right here: $ ls -l /usr/local/lib | grep libstream -rwxr-xr-x 1 root root 943 Mar 9 14:23 libstream.la lrwxrwxrwx 1 root root 18 Mar 9 14:23 libstream.so -> libstream.so.3.1.5 lrwxrwxrwx 1 root root 18 Mar 9 14:23 libstream.so.3 -> libstream.so.3.1.5 -rwxr-xr-x 1 root root 107879 Mar 9 14:23 libstream.so.3.1.5 And there were no errors reported during any of ./configure sudo make sudo make install My installation script was: sudo apt-get install libxml2-dev bison ant flex unixODBC-dev # download and unpack source wget http://dev.monetdb.org/downloads/sources/Latest/MonetDB-11.15.3.tar.xz tar -xvf MonetDB-11.15.3.tar.xz # install cd MonetDB-11.15.3 ./configure sudo make sudo make install Help much appreciated, Duncan
