ModelGUI Wiki Site

Hello,

I have installed mgui 1.0.22-alpha on a Mac OSX 10.8.5, and I have installed java 3D jkd1.8.0.
When I try to run mgui-mac, I got the following error:

mac-5brown:~ lea$ /Applications/MINC/mcgui/mgui-1.0.22-alpha-src/mgui-mac ; exit;
Error: Could not find or load main class mgui.interfaces.exec.MguiStart
logout
[Process completed]

What is the problem and how can I fix it?
Thank you

Hi Lea,

I think the problem is that it needs to be run from the ModelGUI directory itself. Try:

cd /Applications/MINC/mcgui/mgui-1.0.22-alpha-src/
./mgui-mac

You could also put this in an executable bash script if you want to run it from elsewhere.

Let me know if you're still having problems! I plan to include OS-specific installers for the next release, to avoid these issues.

Cheers,
Andrew

Hi Andrew,

thank you very much for the answer. It is improving but still not working. Now I get another exception:

Could not initiate driver 'JDBC-ODBC', class 'sun.jdbc.odbc.JdbcOdbcDriver'
Details: sun.jdbc.odbc.JdbcOdbcDriver
Exception in thread "main" java.lang.NoClassDefFoundError: javax/media/opengl/GLCapabilitiesChooser
[…]
Caused by: java.lang.ClassNotFoundException: javax.media.opengl.GLCapabilitiesChooser
[…]

any idea what that means?

Thanks again!

Cheers,
Léa

Hi again,

Ah, yes this is a Mac-specific issue, which has been fixed with the newest (not yet released) version. Basically, older versions of OSX (i.e., a year old or older) come with an older version of Java3D installed, which for some reason overrides the version which ships with ModelGUI.

The new version (1.0.23) will be released very soon, but if you don't want to wait, the resolution is illustrated here. Basically, you need to remove the old Java3D version:

Go to the following directory: "System/Library/Java/Extensions"
Delete these files (if present): j3daudio.jar, j3dcore.jar, j3dutils.jar, vecmath.jar, libJ3D.jnilib, libJ3DAudio.jnlib, libJ3DUtils.jnilib

Sorry about the confusion! Let me know if this doesn't resolve the issue.
