i am trying to access particular bit of a Port in Pic18f4431 using mikro C. i am using the port as input port by writing TRISC=255;
however i am getting this error, kindly help.

 

I don't see how that could fail unless there's a fairly basic bug in the compiler, where it doesn't know how to control PortC. Is it possible that the bug is in your setup of your project, and you've told the compiler that you have some other processor, which doesn't have PortC?

 

Post the exact code (copy & paste) for lines 51 and 52... also the preceeding few lines.

Sometimes an error in one line will not get detected till a few lines later, so always look what comes before an offending line if it looks perfect.

 

thank you all, the issue was resolved. i was using PORTC.C0 instead of PORTC.RC0.
