Hello and welcome!
your "error" is simple: the nslu does not have the same CPU as your Ubuntu
PC, so it cannot run programs compiled on your pc:
Your pc has a x86 cpu.
The slug has an ARM cpu.
You must either "cross compile" your program for the slug, or run a
on-slug-board gcc adapted to your slug.
1) cross compiling - that means using a gcc that runs on your pc but
generates code for the slug. personnally, I don't know where to find a
simple toolchain to do this - but other people here know it, i'm sure.
2) native compiling on the slug - this requires having added some swap on a
usb stick, then installing the following ipkgs, possibly from optware, I
don't know unslung (I'm a slugos user):
binutils binutils-symlinks cpp cpp-symlinks gcc gcc-symlinks
then you can run the gcc -o test test.c on the slug itself, and it will work
as expected (but not on a pc :) )
