[Tinyos-help] TinyOS and Matlab

[Milton Aguiar]

After doing what you have said, the following error occurs:

1000ton at aguiar-8e616724 /opt/tinyos-1.x/tools/java/net/tinyos/matlab
$ javac MatlabClock.java
Note: MatlabClock.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.

What's the problem now?

Thanks


Milton Aguiar
