Getting a version to run

[Henning Hasemann]

Hi everybody,
I'd like to try out SNEE on a testbed of nodes, however I'm having trouble getting the latest release (from 2011) compiling.
In contrast to the documentation there is SampleClient.java instead of a QueryCompiler.java.
However when I try to compile that, I get:

% javac -sourcepath src -classpath "src:lib/antlr-2.7.5.jar:/usr/share/java/log4j-1.2.17.jar:" \                                                                                      1
  uk/ac/manchester/cs/snee/client/SampleClient.java \
  -d bin

(the list goes on, you get the picture)

Any idea what I might be doing wrong?


Also, this seems only to be the PC side, what should I do to get the images to flash on the nodes?

Hi Henning,

Sorry that you're having problems. At the moment, the two best placed people to help you out are scattered over the planet. Alan Stokes is in SIngapore and Ixent Galpin in Colombia. In both cases, away from their main working environments. As such, and just so that you feel reassured that they'll try to help, the likely date that they will be able to contact you back is around 10-14 February, but may be earlier.

Apologies to make you wait, and thanks for taking an interest in our software.

Best wishes on your work,

Alvaro

Hi Henning,

It looks like you are missing some dependencies.

Could you let us know which version of the system you have downloaded (i.e. the link that you downloaded)?

Have you tried using the maven build approach?

At the top level snee folder you should be able to issue the command

mvn install

Hope that helps.

Alasdair

PS The main developer on the project is currently away until mid February. Myself (and hopefully others) will help you as far as we can, but I’m now working on other things.

Hi Alasdair,
thanks for your quick reaction,
I tried this one:
https://code.google.com/p/snee/downloads/detail?name=SNEE-1.6.4-SNAPSHOT.zip&can=2&q=

which I took as the latest more or less official release (?)
For instructions I looked at https://code.google.com/p/snee/wiki/Getting_Started

It doesnt seem to contain a pom.xml anywhere though.
I also tried building the latest SVN with "mvn install", which spit out an error message as well, see attached files.

Cheers,
Henning

Hi Henning,

The "Getting Started" instructions you are following, with QueryCompiler.java, pertain to the "older" version of SNEE, referred to as "In-Network SNEE", which uses TinyOS 1 (and has QueryCompiler.java as main class -- this is SNEE-r1.0.zip in the downloads sections).  

Our development efforts in recent years have moved on to "Unified SNEE".  We stopped adding releases to the Downloads section because Google Code discontinued the feature to add new files.  I would therefore suggest you pull off code from the SVN and follow the instructions  at https://code.google.com/p/snee/wiki/SettingUpDeveloperEnvironment

What types of motes are on your testbed?  We have in the past generated code for Tmote Sky, Micaz and Mica2.  It's not to say that our code generator will not work for other platforms, but some tweaks may be needed.

Cheers,

Ixent

Hi

What version of Java are you using?

I think the 1.7 library changed the ResultSet API and the code will not work with it.

Hey guys,
sorry for the late reply -- somewhat busy with different things atm --
switching to java 1.6 made the mvn install / mvn package possible, thanks for the hint!

I'm still confused though on how I might proceed, or even what I just compiled ;)
What I would like to try to do is execute a simple query on a number of tmote sky motes.
How do I generate the code for the motes? How do I run a simple query?

Sorry if the answer to these is actually obvious and I might just not see it :)
