First download the linux installer (see Xilinx Download site) Extract the archive Download from launchpad : libpng12 and libfreetype6 - https://launchpad.net/ubuntu/xenial/+package/libpng12-0 - https://launchpad.net/ubuntu/xenial/amd64/libfreetype6/2.6.1-0.1ubuntu2.5 Extract the .deb files to /tmp/ - dpkg-deb -xv libpng12-0_1.2.54-1ubuntu1_amd64.deb /tmp/ - dpkg-deb -xv libfreetype6_2.6.1-0.1ubuntu2.5_amd64.deb /tmp/ copy the libs in the lib/lin64 directory of the ISE folder (Xilinx_ISE_DS_Lin_14.7_1015_1) - cp /tmp/usr/lib/x86_64-linux-gnu/libfreetype.so.6 ./ - cp /tmp/usr/lib/x86_64-linux-gnu/libpng12.so.0 ./ and start the installer : sudo ./xsetup Voilà, it works now :) Repeat the operation in the install directory /opt/Xilinx/14.7/ISE_DS/ISE/lib/lin64 Thanks http://insanity4004.blogspot.com/2019/06/making-xilinx-ise-147-run-on-ubuntu-1804.html for the tip.
