  1. Hello, I have brushed the dust off my Papilio Pro, and am trying to get the DesignLab IDE running on Ubuntu 16.05 LTS. I have installed and licensed Xilinx ISE 14.7_1015_1 as WebPack ISE seems to run fine... I installed the default-JRE as sudo apt-get install default-jre java -version openjdk version "9-internal" OpenJDK Runtime Environment (build 9-internal+0-2016-04-14-195246.buildd.src) OpenJDK 64-Bit Server VM (build 9-internal+0-2016-04-14-195246.buildd.src, mixed mode) I downloaded and set-up DesignLab as DesignLab-1.0.8-linux64.tgz, by running I get errors when starting DesignLab: 1. JRE Version Problem $ ./DesignLab Exception in thread "main" java.lang.ExceptionInInitializerError at at Caused by: java.lang.NumberFormatException: For input string: "9-i" at jdk.internal.math.FloatingDecimal.readJavaFormatString(java.base@9-internal/ at jdk.internal.math.FloatingDecimal.parseFloat(java.base@9-internal/ at java.lang.Float.parseFloat(java.base@9-internal/ at java.lang.Float.<init>(java.base@9-internal/ at processing.core.PApplet.<clinit>(Unknown Source) ... 2 more Problem seems to be that the Processing IDE base being used searches for a single digit version JRE 2. Missing libraries I used nix-shell to create an environment with a different JRE, I just used the default jre. I'm not claiming this is anything other than a blind hack. I don't do java. $ java -version openjdk version "1.8.0_121" OpenJDK Runtime Environment (build 1.8.0_121-13) OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode) When I run ./DesignLab, the java. errors disappear, but I then get GTK errors: $ ./DesignLab Gtk-Message: Failed to load module "overlay-scrollbar" Gtk-Message: Failed to load module "canberra-gtk-module" I've tried all sorts of stuff - loaded every variant of GTK I can find.. I believe it is an interaction between the 'skin' of the java app and the jre. Can anyone offer a solution? Or.. Can anyone tell me what jre the original Processing IDE was delivered with/ or is compatible with? Cheers, -- Peter G
