I got this same error when running on a headless server (after playing with execstack for a while in a wild goose chase).

Try running it with DISPLAY defined.

I have same problem. It's weird, because few weeks ago it worked fine. Maybe new java version is the problem?

I'm running into this problem under Ubuntu as well. From the error message, it seems to indicate that it is trying to access 32 bit libraries on a 64 bit system.

I looked in the ~/.tectonicus/native and there are a few .so libraries that get deposited at some point, which include both 32 bit and 64 bit .so files. The 32 bit files seem to be running erroneously.

What I did to hack around this problem was to open up the jar file and replace the 32 bit .so files with their 64 bit equivalents.

That seemed to get me a little farther, but then I ran into another UnsatisfiedLinkError:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/ubuntu/.tectonicus/native/liblwjgl.so: libjawt.so: cannot open shared object file: No such file or directory
at java.lang.ClassLoader$NativeLibrary.load(Native Method)

I've ensured that libjawt.so was in the classpath, but that didn't help. At this point I am giving up and going to bed.

Yea, im getting this error too on Ubuntu Server 13.10. Has a solution been found?

Initialising display...
OpenJDK 64-Bit Server VM warning: You have loaded library /root/.tectonicus/native/liblwjgl.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c ', or link it with '-z noexecstack'.

I'm a bit late to the party, but here goes: Running on a headless machine takes extra steps which can be found here: http://minecraft.gamepedia.com/Programs_and_Editors/Tectonicus/VPS

Also try setting force64BitNatives to true.
