When I try to compile the Timer1 interrupt example for the PIC32MX460F512L
from the Compiler examples Folder
I get Failed with no errors and no error hint is given ,however the EnableInterrupt Function
in the initialization code remains underlined in Red as if the compiler does not find this function
I then made a new Project and used the Interrupt tool to generate me the interrupt handler for
Timer 1 this Interrupt handler does not compiler !!
I did read the Help file

* NOTES:
- Use the ORG directive to declare your procedure as an interrupt service routine.
The address after the ORG statement indicates which interrupt you will assign to
your procedure.
Please consult the datasheet for your MCU for interrupt vector table
details and available addresses.
- Also, consult mikroC PRO for PIC32 help on how to use interrupts.
