[Solved] MATLAB 2012a: -nodesktop and libjvm.so

Hey forums.

I have a (hopefully) easy question.  I've recently installed MATLAB 2012a, and with reasonable hassle its working.  However, I would like to be running it with the -nodesktop command so I can properly tile things in DWM and/or tmux.

Problem is, I get an error saying:

Warning: Unable to load Java Runtime Environment: libjvm.so: cannot open shared object file: No such file or directory.

I'm assuming this has something to do with me having an x86_64 archlinux trying to install x86 MATLAB, as I've encountered this trouble with other shared libraries (lib32-glu for example), and for those I just found the right package in the multilib repository.  However, I can't find what potential multilib package I should install to get libjvm.so.

I have jre7-openjdk installed with jre6-compat and jdk6-compat (I have issues with java7 with matlab but don't feel like using 6 for everything else).  I followed the wiki article to install lib32 packages (and had to add lib32-glu).  I am using the jre included with Matlab (from the same wiki article), but I've tried using bin32-openjdk6 and I get:

Warning: unable to find Java library: /usr/lib/jvm/java-7-openjdk/jre/lib/i386/libjava.so

What am I missing?  Or am I crazy hoping there is some magical multilib-like solution? Note that Matlab does run with -nodesktop, but a lot of java-related functions don't work.  Thanks.

Re: [Solved] MATLAB 2012a: -nodesktop and libjvm.so

Hi,

I have been using R2012a several months, with the -desktop option, wihthout any warning.
Now I am using the R2012b release, also with -desktop option, also without any warning or problem.

So I guess you have something missing.

Hopefully the following could help :

Thanks for the reply!

The -desktop option works fine for me, it's only the -nodesktop option that is having trouble.  Also, do you have a 32bit or 64bit system?  Because I know there are troubles inherently with that too.  Here is what I have installed (probably overkill on the 6 compat stuff, but I've been trying...)

Re: [Solved] MATLAB 2012a: -nodesktop and libjvm.so

Hi, I too use Matlab 2012a without any issues, glnxa64, on a x86_64 system. Why not just install the 64 bit version instead of the 32 bit?
All my Matlab installs, been using it for some years now sad, have been without any hassle what so ever.
These are my java packages:

Re: [Solved] MATLAB 2012a: -nodesktop and libjvm.so

Unfortunately, I bought the Student Version and they only provide you with the x86 version :-(

Honestly, their whole licensing setup drives me nuts but I need it for research so what can I do!

I've put in a ticket with their Technical Support, even though I don't have a supported distribution... I figure it shouldn't matter since I'm using the JRE they shipped anyways.  Any other ideas would be appreciated though, and thanks for the help so far...

Weird, I think I've got the student version too, and I've been able to update and choose versions for years. Have you tried a 32 bit chroot?

Re: [Solved] MATLAB 2012a: -nodesktop and libjvm.so

Alright, so it was an easier solution than even I thought.  If you want to run it terminal mode (-nodesktop), you need to be sure to append -glnx86 as well.  I added that to the .desktop file for -desktop mode, and forgot to append it when typing manually.  Thanks for the help!
