UPDATE: I've put together some Debian packages. I've tested these in Linux Ubuntu 11.10. However, I'm extremely new to the whole package management and distributing applications in Linux, so your mileage may vary. I have no idea whether the packages will install on other Linux flavors. Someday soon I'll create a VM with something other than Ubuntu and try it.
There's three Debian packages on my
website.
First you'll need to download/install libnesicide-emulator_1.004-1_i386.deb. This installs the NES emulator shared library that's used by NESICIDE and its companion stand-alone emulator.
Then you'll need to download/install nesicide_1.014-1_i386.deb if you want the main IDE and/or nesicide-emulator_1.004-1_i386.deb if you want the stand-alone emulator.
On a *clean* Ubuntu installation, I find I have to do:
sudo apt-get -f install
after trying to install either of the application packages. That's because they depend on some Qt libraries that aren't installed. dpkg doesn't automatically install dependencies, so you have to use apt-get to do it.
When installing nesicide_1.014-1_i386.deb, after it's done it'll give you the steps to download/compile/install CC65 snapshot toolchain. Do this if you don't already have it. NESICIDE will still be able to load, play, and debug ROMs, but it won't be able to compile-and-run changes to ROM source without CC65 [I know this is probably obvious].
I'm presently working on getting the example projects back online...I'll repost when they're available.
Please let me know if you try this and what your experience is. I'm very interested in providing my tool in Linux!
