Virtuoso 7 Installation Notes

ubuntu-virtuoso7-shell-history.sh

# For ubuntu 16.04, ppa:ondrej/php repository also includes openssl > 1.1.0 which is incompatible with virtuoso.
# To build virtuoso, version 1.0.2 is needed which exists in the default ubuntu repos.
# Remove the repo above with
# sudo add-apt-repository --remove ppa:ondrej/php
# and re install openssl 1.0.2. After the compilation of virtuoso, you can upgrade the openssl version without breaking
# Virtuoso.

sudo apt-get update
sudo apt-get install autoconf automake libtool flex bison gperf gawk m4 make openssl libssl-dev 
sudo apt-get install git wget curl libreadline-dev
sudo git clone https://github.com/openlink/virtuoso-opensource.git /tmp/virtuoso
cd /tmp/virtuoso
sudo git checkout stable/7
sudo ./autogen.sh 
export CFLAGS="-O2 -m64"
sudo ./configure
sudo make
sudo make install

# Create appropriate links.
sudo ln -s /usr/local/virtuoso-opensource/bin/virtuoso-t /usr/local/bin/virtuoso-t
sudo ln -s /usr/local/virtuoso-opensource/bin/isql /usr/local/bin/isql

Since Virtuoso, as of the moment of writting this comment, does not yet support custom build with openssl1.1, you can install openssl1.0 without removing 1.1 and target this version for the configuration.

sudo apt-add-repository -y ppa:rael-gc/rvm
# If needed
sudo apt update
# Below, change the version with the corresponding latest version of 1.0.
sudo apt-get install -y --allow-downgrades openssl1.0=1.0.2n-1ubuntu5.3

Now, change in the above script, the ./configure with

# And in the above virtuoso guide, change the `./configure` with
./configure --enable-openssl=/usr/lib/ssl1.0

This is now the best candidate I think. https://github.com/feup-infolab/virtuoso7-debs
