Regarding an error

[ZALA ARYANSINH via Tech-talk <tech-talk at aps.anl.gov>]

Hello, 

I am currently following a project from the site mentioned below. 

https://web.archive.org/web/20180417224946/http://www.smolloy.com/2015/12/epics-serial-communication-with-arduino/

I have successfully done the previous mentioned steps. Also a point to note that i am using a virtual machine as i could not install linux on my desktop. 

The error that i am facing is:

#!../../bin/linux-x86/helloWorldIOC
