I receive the following linker error when I link my RTX166 program.
*** ERROR 124: INTERRUPT NUMBER ALREADY USED
What causes this message and how can I correct it?
This message is caused when the linker detects that there are two interrupt service routines for the same interrupt trap.
Refer to the Interrupt Procedures section of the linker MAP file and look for interrupt procedures with the same interrupt number:
INTERRUPT PROCEDURES OF MODULE: vsfd (MAIN) INTERRUPT PROCEDURE INT INTERRUPT NAME ===================================================== rtx_nmi_handler 2 --- rtx_btrap_handler 10 --- NMI_trap 2 --- STKOF_trap 4 --- STKUF_trap 6 --- Class_B_trap 10 --- ?C_RESET 0 RESET rtx_167int_16 16 --- rtx_167int_17 17 --- rtx_167int_18 18 --- rtx_167int_19 19 --- rtx_167int_20 20 --- . . . rtx_167int_70 70 --- rtx_167int_71 71 --- rtx_stkovf_handler 4 --- rtx_stkunf_handler 6 ---
As you can see in the above listing,
The NMI_trap, STKOF_trap, and STKUF_trap interrupt service routines are created when you include the TRAPS.C file from the c166lib directory. Remove this file from your project and re-compile your program.
