[Tinyos-help] Environment variables setting for TinyOS 1.1.15 on Windows

[Michael Schippling]

There are two separate but equal paths...

CLASSPATH is used by Java to find classes and jar files,
you seem to be on the right "path" to getting that set correctly.

PATH is used by the bash shell (and internal Widows executor) to
find executable programs. Most of the complaints in your original
message, e.g., "Warning: No ncc in current path", are from not
having this set correctly -- unless of course there really is no
"ncc" installed...

This may help a bit:
     http://docs.tinyos.net/index.php/Java_cygwin

as well as googling both CLASSPATH and PATH for more details on
how they work. And try "man bash" for details on the shell itself.

You can see variable values by typing "echo $PATH", etc, or "env"
to see everything. export VAR="stuff" will set a variable in
the current shell. Just to make things interesting, directories
in the cygwin bash shell PATH variable need to be referenced
relative to the cygwin install with colon ':' separators like this:
     PATH=/usr/X11R6/bin:/cygdrive/c/JAVA/jdk1.5.0_16/bin
and in CLASSPATH relative to the windows drive nomenclature with
semicolon ';' separators:
     CLASSPATH=C:/cygwin/opt/moteiv/tools/java;C:/cygwin/opt/someother.jar

I have heard that TOS does not play well with Vista so you may
be on your own hacking through the problems.
