ModelGUI Wiki Site

Hello guys!
Your app looks amazing, but I really cannot manage to make it run. I followed the instructions in the README and in the forum, but I cannot get it to run.
Can you please help me with that?
Thank you very much in advance!

I am using a MacBook Pro (2014) with OS X 10.9.5, and I downloaded mgui-1.0.22-alpha release from the mgui-core series released 2014-06-01.
The JDK is installed in:
/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk

and this is the output of java -version:

java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode

If I use the command for mac in the README, which has the amd64 option, I get:

~/Downloads/mgui-1.0.22-alpha: java -Djava.library.path=bin/amd64 -Xmx1000m -classpath .:lib:lib/* mgui.interfaces.exec.MguiStart mgui.mac.init
Error: Could not find or load main class mgui.interfaces.exec.MguiStart

If I use the mgui-mac command, which has the i586 option, I get:

~/Downloads/mgui-1.0.22-alpha:  ./mgui-mac

Hi Leonardo,

Thanks for your interest in the software!

Looks like an issue with the dependency library (Java3D was updated, but one or more of the new files don't seem to have made the lib directory). The download file for mgui-1.0.22-alpha has now been updated. You can get it at:

https://launchpad.net/modelgui/mgui-core/mgui-1.0.22-alpha/+download/mgui-1.0.22-alpha.zip

This runs on my nearly identical MacBook with Java 8. Use the command:

./mgui-mac

Let me know if you have any other issues! Also look out for a new version to be released very soon — since I'm now developing on a Mac, many of the Mac-related bugs have been worked out; also, a Mac dmg will be released that can be simply dragged to Applications and run.

Hello Andrew!

thank you for your reply! I downloaded the updated version from the link you posted. Unfortunately the output is identical to the one I previously posted…
Is there any way that I can set a path for the files to be found?

all the best!
leonardo

Hi again,

Strange, it works for me. All necessary dependencies are in the "lib" directory. They include the following:

gluegen-rt-natives-macosx-universal.jar
gluegen-rt.jar
joal.jar
jocl.jar
jogl-all-natives-macosx-universal.jar
jogl-all.jar
jogl.jar
vecmath.jar

Can you check the contents of 'System/Library/Java/Extensions'? This should be empty, or at least contain no (very obsolete) Java3D files, which conflict with the newer version of Java3D that is in ModelGUI's lib folder. If the following files are in there, you can safely delete them:

j3daudio.jar
j3dcore.jar
j3dutils.jar
vecmath.jar
libJ3D.jnilib
libJ3DAudio.jnlib
libJ3DUtils.jnilib

This has been a constant headache with OSX; I am considering adding the JRE directly to the download file to avoid depending on the system JRE in the future.

Let me know if this helps or not.

Cheers,
Andrew

a-ha! I think I have a go here :O)

I forgot to re-delete the j3* files from the System/Library/Java/Extensions after I had tried it with the downloaded version.
I now deleted them for good, and with this version, it works! :O)

thank you so much for all the help!
all the best,
leonardo

Good to hear :) Have fun with it!

Hi, I’m having similar troubles, any help appreciated.

When I try to start mgui, I get the following message:

C:\Program Files\Mgui\mgui-1.0.22-alpha>java -Djava.library.path=bin\amd64 -Xmx1000m -classpath .;*;lib;lib\* mgui.interfaces.exec.MguiStart

[…]

Running Windows 7, and have the latest version of mgui. I checked that these files are not present elsewhere but in the mgui directory.

j3daudio.jar
j3dcore.jar
j3dutils.jar
vecmath.jar
libJ3D.jnilib
libJ3DAudio.jnlib
libJ3DUtils.jnilib

Also (the aforementioned) files (e.g. glugen-rt.jar) are found in mgui\lib directory
I should have the latest Java version installed:

java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)
