MatLab with Ubuntu 11.10

Under the new Ubuntu release (11.10 Oneiric Ocelot), trying to run MatLab gets the following error

1

/opt/MATLAB/bin/util/oscheck.sh: 605: /lib64/libc.so.6: not found

MatLab will still load, but will effectively be useless and can only be closed by killing the process. Furthermore, my previous trick of

1

sudo ln -s /lib64/x86_64-linux-gnu/libc-2.13.so /lib64/libc.so.6

On closer inspection, the libc.so.6 link exists in /lib64 however the file it actually points to (/lib64/x86_64-linux-gnu/libc-2.13.so) does not exist, thanks to the update it’s moved

For 64 bit:

Remove old link

1

sudo rm /lib64/libc.so.6

(Be careful when removing the old link. It is essential for Linux to boot. So if you reboot before replacing the link with the new version then it’ll be time to dig out a live disk. If you’re paranoid then you can copy cp the libc.so.6 file to something like libc.so.6.backup first.)

Replace with new link

1

sudo ln -s /lib/x86_64-linux-gnu/libc-2.13.so /lib64/libc.so.6

For 32 bit:

(I have not tested this as I only run x64 systems, but from the comments I think it should work)

Remove old link (again be careful with this command)

1

sudo rm /lib32/libc.so.6

Replace with new link

1

sudo ln -s /lib/i386-linux-gnu/libc-2.13.so /lib/libc.so.6

Of course if this is a fresh Ubuntu install then you probably wont need the rm (remove) command.

This is the second part of the lab server setup guide. Mainly for my own memory purposes, but if you find it useful then so much the better.

Frequently asked questions

What distinguishes you from other developers?

I've built data pipelines across 3 continents at petabyte scales, for over 15 years. But the data doesn't matter if we don't solve the human problems first - an AI solution that nobody uses is worthless.

Are the robots going to kill us all?

Not any time soon. At least not in the way that you've got imagined thanks to the Terminator movies. Sure somebody with a DARPA grant is always going to strap a knife/gun/flamethrower on the side of a robot - but just like in Dr.Who - right now, that robot will struggle to even get out of the room, let alone up some stairs.

But AI is going to steal my job, right?

A year ago, the whole world was convinced that AI was going to steal their job. Now, the reality is that most people are thinking 'I wish this POC at work would go a bit faster to scan these PDFs'.

When am I going to get my self-driving car?

Humans are complicated. If we invented driving today - there's NO WAY IN HELL we'd let humans do it. They get distracted. They text their friends. They drink. They make mistakes. But the reality is, all of our streets, cities (and even legal systems) have been built around these limitations. It would be surprisingly easy to build self-driving cars if there were no humans on the road. But today no one wants to take liability. If a self-driving company kills someone, who's responsible? The manufacturer? The insurance company? The software developer?
