[Scilab-users] Scilab on Mavericks with Java 7?

[John Haggerty]

Hello,

Thanks for the informative advice.  I still can't start scilab, but I 
know a lot more about where java 7 goes in OS X.

The method used does not find a valid JVM:

This does not look good from SCIVERBOSE=1 bin/scilab:

I saw that bug, but adding a link to 1.5 doesn't help; I can't find any 
errors that point me to where it wants the jre.  scilab -debug just 
tells me the same thing--no java runtime.

I might try that at some point, but I'm not committed enough to getting 
scilab running (yet).

Very informative, but my java installation seems perfectly clean:

> /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home

Maybe scilab just doesn't work with Java 1.7?
