If you are running from the command line, it should print errors to the console if there was a problem.
It will not report errors if your component exits, eg from an exit() function call, or the program just runs to the end of the file. The python example, http://www.linuxcnc.org/docview/html//hal_halmodule.html, has a while loop that spins forever. The script is terminated by halrun when it is finished. > -----Original Message----- > From: Leonardo Marsaglia [mailto:leonardomarsagli...@gmail.com] > Sent: Tuesday, 17 November 2009 10:06 AM > To: Enhanced Machine Controller (EMC) > Subject: Re: [Emc-users] Link a Bash script to a hal signal > > Thank you Frank, i could load the python scripts.. the > example for now.. > > i have a problem with my script.. when i load it and enter > the halcmd show.. > nothing appears.. only the halcmd application.. but my > component doesn't. > > Is this because there is an error in the python code? > > Regars. > > Leonardo. > > 2009/11/14 Frank Tkalcevic <fr...@franksworkshop.com.au> > > > In a hal file, you use the loadusr command.
