Hi, 

I got the following error when trying to use tinyviz (with the tinyviz -run 
/build/pc/main.exe 30)

[EMAIL PROTECTED]:/opt/tinyos-1.x/apps/TestTinyViz$ tinyviz -run 
build/pc/main.exe 30
java -Dpython.cachedir=/tmp/jython.cache -DDBG=usr1 -DSIMDBG= 
net.tinyos.sim.SimDriver -gui -run build/pc/main.exe 30
Starting SimDriver... 
Simulation random seed 1341307903
Initializing simulator objects...
getenv JNI library not found. Env.getenv will not work
(please consult installation directions in
tinyos-1.x/tools/java/net/tinyos/util/Env.INSTALL)
Loading simulator plugins...
Exception in thread "main" java.lang.NullPointerException
        at net.tinyos.sim.PluginManager.register(PluginManager.java:77)
        at net.tinyos.sim.SimDriver.<init>(SimDriver.java:258)
        at net.tinyos.sim.SimDriver.main(SimDriver.java:539)


Any way to solve this???


Also :
sudo tinyviz -run build/pc/main.exe 30

throws an error which i think is odd since, to make the apps, i have to sudo
all the time in ubuntu (e.g. sudo make pc or sudo make mica2)
