Hello Friends
I am working on RTLinux. In the work I am facing a problem. The problem is that
When I run the program given below then it gives me a number of errors which when
comes continue to come continuously and my screen is filled with errors rather it
overfills and then continues so I am not able to see first few errors.
Please help me to provide some GUI Interface to solve this problem or tell me some
other way.
Waiting for Reply
