For the first error (`GLIBCXX_3.4.21' not found) try the other Linux version (the one marked as GCC 4.9.3). This was the reason I uploaded it.

For the second error (at least on Ubuntu 14.04) it seems that some dependency is missing but ldd doesn't report it. Under Ubuntu 14.04 ldd maps /lib/ld-linux-x86-64.so.2 to /lib64/ld-linux-x86-64.so.2 but when you try loading the executable this doesn't happen. If this is the case for you, try creating a symlink:

ln -s /lib64/ld-linux-x86-64.so.2 /lib/ld-linux-x86-64.so.2

Hope that helps.

Yeah, there aren't any yet. As I said in another comment, I have a couple of ideas on how to turn it into a game. Currently I cannot decide which one I'll be able to implement in finite time and if it'll be any fun to play.

It's at the bottom of my looong TODO list. Hope to find some time to try it out. Don't know if and how it'll work though.

You should do it! I doubt I'll decide how to turn DLS into an actual game sooner than you are able to build yours :)

One of my ideas is similar to what you describe but with more complex cases (I can't think of anything simple that will make sense). E.g. controlling traffic lights.

Thanks!

There are currently no objectives or any game element in DLS. I have some ideas on how this can be turned into a game. Haven't decided which of them will be feasible to implement and be (somewhat) fun at the same time.

The i4004 was the first real thing I tried to simulate in DLS (I thought it would be easy since it's only a 4-bit CPU... :)). As you said, it's mostly the real deal, since it's missing some components. That's why I added scripting to see if it can make the whole process a bit simpler.

When scripting was implemented, I didn't want to redo the i4004, that's why I started the 6502. And since kernel and basic ROMs were available online, I thought of adding a display to see if I can get some output.

AFAICT, building an entire CPU out of logic gates in DLS is feasible. I just don't have all the time required to do it, that's why I'm currently building (reusable?) parts of a CPU and document the process in the blog. It will be complete some day, but not anytime soon :)
