Unfortunately, I (Traumflug) couldn't get this to work:
> java -jar visolate-2.1.6.jar Exception in thread "main" java.lang.NoClassDefFoundError: javax/media/j3d/WakeupCriterion [...]
- Visolate requires libraries from the java3d project in order to work properly. Precompiled jars, installers and source code are available from java.net. - Xsainnz 12:31, 23 October 2010
Thanks a lot, Xsainnz. Could you elaborate on which libraries are needed. And also, how to do this without installers, because on packaging-based Linux's using installers is a bit a no-no. Traumflug 16:21, 23 October 2010 (UTC)
Not to forget: java-3d is installed here, so this is probably an incompatibility with 64-bit Linux/Ubuntu. Traumflug 16:25, 23 October 2010 (UTC)
- There are installers and zip binaries for multiple system on the downloads page have you tried the one for your system?
- How do you know java-3d is installed and working? - Xsainnz 07:57, 24 October 2010 (UTC)
I assume java-3d is working, because I've installed it via the (hopefully) appropriate Ubuntu package and RepRap host works as well. Traumflug 09:54, 24 October 2010 (UTC)
- I borrowed a friends 64bit laptop, so I've been able to get visolate to work on Ubuntu 10.10 (64bit).
- I have also been able to replicate the error you reported.
- The error message you posted indicates that java cannot find the j3d libs.
- The easiest method was to installing j3d with the synaptic package manager (libjava3d-java, libjava3d-jni & libvecmath-java)
- Alternately you can manually download "j3d-1_5_2-linux-amd64.zip" from Java 3D Downloads
- Extract the zip to somewhere convenient, then extract the contained zip (j3d-jre.zip)
- We will assume (for now) that java can find the shared object (".so") file/s as you have said you have the Reprap host installed and working
- inside the "lib/ext" folder you just extracted should be three jars (j3dcore.jar j3dutils.jar & vecmath.jar)
- Copy the three jars to the JRE external library folder, on the 64bit system this was "/usr/lib/jvm/java-6-openjdk/jre/lib/ext" the 32bit Ubuntu jvm was sun java so the path was slightly different
- Try running the visolate jar again. Any luck? --Xsainnz 13:57, 27 October 2010 (UTC)
Thanks a lot for the help, Xsainnz. I hope I can find the time to try this soon - it's not forgotten. Traumflug 07:30, 29 October 2010 (UTC)
OK, so I finally found the time to try again:
sudo apt-get install --no-install-recommends libjava3d-java libjava3d-jni libvecmath-java sudo update-java-alternatives -s java-6-sun sudo ln -s /usr/share/java/j3dcore.jar /usr/lib/jvm/java-6-sun/jre/lib/ext sudo ln -s /usr/share/java/j3dutils.jar /usr/lib/jvm/java-6-sun/jre/lib/ext sudo ln -s /usr/share/java/vecmath.jar /usr/lib/jvm/java-6-sun/jre/lib/ext sudo ln -s /usr/lib/jni/libj3dcore-ogl.so /usr/lib/jvm/java-6-sun/jre/lib/ext/ java -jar visolate-2.1.6.jar
as well as:
sudo apt-get install --no-install-recommends libjava3d-java libjava3d-jni libvecmath-java sudo update-java-alternatives -s java-6-openjdk sudo ln -s /usr/share/java/j3dcore.jar /usr/lib/jvm/java-6-openjdk/jre/lib/ext sudo ln -s /usr/share/java/j3dutils.jar /usr/lib/jvm/java-6-openjdk/jre/lib/ext sudo ln -s /usr/share/java/vecmath.jar /usr/lib/jvm/java-6-openjdk/jre/lib/ext java -jar visolate-2.1.6.jar
the error is both times the same:
# A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007f4da985d12e, pid=17619, tid=139971522557696 # # JRE version: 6.0_22-b04 # Java VM: Java HotSpot(TM) 64-Bit Server VM (17.1-b03 mixed mode linux-amd64 ) # Problematic frame: # C [libGL.so.1+0x5612e] XF86DRIQueryVersion+0xae # # ...
Java is really a nightmare *sigh* Thanks anyways, Xsainnz, at least I got beyond the NoClass error. Traumflug 21:10, 3 December 2010 (UTC)
BTW:, currently neither visolate nor Blender, Meshlab or RepRap Host run. All with the same libGL error. Traumflug 20:43, 4 December 2010 (UTC)
Got it to work, finally. EMC2 had installed fglrx (nVidia graphics drivers) as a dependency and this is incompatible with Intel graphics drivers. Updated the main page. Traumflug 00:32, 5 December 2010 (UTC)
PCB->G-code, new tool
Hi! I apologize if this is not the right place, and please just delete this if it isn't. Could you add http:/ /rapid-pcb.com to the list of tools for PCB to G-code generation?
Best regards, Paul
