  1. Hi Jack, That's a good result then. Unfortunately my workstation has more history than a fresh vagrant image. There is constant frustration trying to run development environments in a reproducible environment. I have been trying to use nix-shell manage the problem recently - works nicely with Stack/Haskell. I was concerned about having problems with the USB drivers if I ran DesignLab in a virtual environment, seemed pretty heavyweight to include ISE as well. Configuring interacting docker instances seems to be difficult and ever-changing. I am considering trying out Ubuntu's Snaps as a solution. There is quite a nice Smalltalk implementation that I'd like to look at, but it is extremely hard for anyone but the sole developer to get the environment running. Anyway - my lack of java config skill was to blame. DesignLab seems easy to configure - amazingly interesting. Well done! Cheers, --Peter G
  2. Hi Jack, As an experiment, I tried a different java configuration, using: sudo update-alternatives --config java to set my JRE to java-8-openjdk-amd64, and set JAVA_HOME. Everything aso worked properly there. I believe my problems were because my system did not have JAVA_HOME set by default. Because of this many java libraries were not found, causing all sorts of errors which looked in google like particular libraries were missing. So, maybe as part of the guide to setting up, ask people to check their jre/jdk is properly installed - using this link (or something more generic) as a guide: --Peter G
  3. Hi Jack, All working - successfully loaded and ran the DesignLab quickstart project, following the getting started video. I installed the Oracle JAva-7 jre - following these instructions, including setting $JAVA_HOME I reinstalled the usb/serial port libraries: sudo aptitude reinstall libftdi-dev . Then I checked the ports were mapped properly: $ dmesg | grep tty [ 0.000000] console [tty0] enabled [ 2930.811615] usb 6-2: FTDI USB Serial Device converter now attached to ttyUSB0 [ 2930.813609] usb 6-2: FTDI USB Serial Device converter now attached to ttyUSB1 [ 3233.928989] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0 Followed the instructions in the video Pretty simple really - once I knew what to do Cheers, --Peter G
  4. 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
