Hi,

I tried to reinstall the pwrdemo45 package:
\"apt-get --purge remove pwrdemo45\"
\"apt-get install pwrdemo45\"
The same error message continued.

I then reinstalled Ubuntu 8.04, before installing the packages pwr45 and pwrdemo45 by double-clicking the deb-files. I gave the pwrp user admin rights.

When logging in as the pwrp user I no longer got the \"*** stack smashing detected ***\"-error when running the command \"rt_ini &\". I got the terminal output given below. What is the cause of these error messages?

pwrp@Ubuntu-Desktop-8/pwrdemo45/-.login> /usr/pwr45/os_linux/hw_x86/exp/exe/rt_webmon.sh: 24: /usr/local//bin/java: not found
/usr/pwr45/os_linux/hw_x86/exp/exe/rt_webmonmh.sh: 23: /usr/local//bin/java: not found
/usr/pwr45/os_linux/hw_x86/exp/exe/rt_webmonelog.sh: 24: /usr/local//bin/java: not found

Thereafter I ran the \"rt_xtt -u op\"-command, which initially gave some \"Open Display errors\", but worked after I gave the user increased privileges (maybe not the reason).

Hi,

The webmon-errors is due to that jdk is not set up properly. You should have $jdk and $jdk_home set up to where you have jdk installed.

For example it could be like:

export jdk=/usr/local/jdk1.6.0_10
export jdk_home=/usr/local/jdk/1.6.0_10/bin

Check if you have soemthin like this in .bashrc for user pwrp.

The sched_setscheduler is due to that Proview fails to set real time priorities. This is not really needed in a simulated environment. If you want it set root as owner and pwrp as group to rt_prio in $pwr_exe directory and set the s-bit (chmod g+s).

The same is needed to be done to the plc-program.

Hi,

Now I have got ProView up and running.

Thank you very much for your help!
