Unable to start Matlab

[kugel]

Hi Everyone,

i am new to gentoo and like it very much so far!
I was able to solve all my problems without asking here but i just can't get Matlab R2012a to start on my machine.

It just gives me:

# ./matlab
Bus error

and thats all
I am running gentoo with kernel 3.2.12 on amd64 and my JVM is icedtea7

Sorry if i did not provide enough information, please ask and i will post it.

Thank You!

First rough idea - can you try oracle-jre-bin-1.7 instead of icedtea?

My thoughts (meaning they may not be helpful at all):

• If you just need to execute some rather simple code, consider porting it to numpy+scipy+matplotlib.
  
• If you are using matlab in a University environment with licenses distributed over network, you may have to wait for other people to finish their work.
  
• Hard to tell which Bus that is supposed to be. Perhaps DBus (but I doubt that). It that's the case, try starting it through openRC (provided it is installed, as it should be with the standard desktop profile and some decent DE/WM) by executing (as root)

  Code:

  rc-service dbus start

  
  If that helps, place the dbus service into the default runlevel

  Code:

  rc-update add dbus default

  
  
• try running

  Code:

  ./matlab -debug

  for more info
  
• Why did you use the hash (#) symbol? if that means you are running it as root, try it as a normal user.

Hey!

Thank you for your replies
But unfortunately it still does not work and matlab does not give me anything else except "Bus error".
DBus is running and switching to oracle-jre-bin-1.7 did not help.

Any suggestions?

Yes. "Bus error" doesn't mean what most people think it means. It means you're out of shared memory (not swap space, nor is it related to dbus), which is directly related to the amount of physical memory you have, at least in the standard Gentoo setup. You have a line in your /etc/fstab something like

Hi John,

thank you for your reply, my fstab looks like this but it still does not work. I have 16GB of RAM so i don't think half of it is not enough for tmpfs, or is there another problem with my fstab?

im getting a bunch of pc's refreshed soon at work and one is fore simulation and I have a dedicated licence of matlab for this machine, ill try then
