Hi Wahid, Errno 2 usually means "File not found"
Does /usr/PTII/bin/.ncapp2moml-util exist and is it executable? I have: bash-3.00$ ls -l $PTII/bin/.ncapp2moml-util lrwxrwxrwx 1 cxh labstaff 8 Dec 15 02:42 /home/eecs/cxh/ptII/bin/.ncapp2moml-util -> ptinvoke If you don't have .ncapp2moml-util, then you will need to run configure and make. See the installation instructions. The short form is cd $PTII ./configure cd bin make To debug this, you could try running the command by hand. _Christopher -------- Hi, I am trying to run apps/Blink in viptos.(the demo is already there in place but i wanna experience the conversion myself) So i run the following command: ./ncapp2moml apps/Blink I got an error as the result : system "apps/Blink" failed: 2 at /usr/PTII/ptolemy/domains/ptinyos/util/ncapp2moml/ncapp2moml-main line 158 I went to the above mentioned line in that file printed the value of $ncapp2momlcmd(in case you require for debugging): /usr/PTII/bin/.ncapp2moml-util /usr/PTII/vendors/ptinyos/tinyos-1.x /usr/PTII/vendors/ptinyos/momlapp .ncxml .opts /usr/PTII/vendors/ptinyos/momlapp /usr/PTII/vendors/ptinyos/momlapp/.ncapp2moml-tempfile /usr/PTII/ptolemy/domains/ptinyos/lib/MicaBoard.xml >> /usr/PTII/vendors/ptinyos/momlapp/ncapp2moml-log.txt 2>&1 I appreciate your help. wahid -------- ---------------------------------------------------------------------------- Posted to the ptolemy-hackers mailing list.
