upload error when creating two libraries together

#include <RCSwitch.h>

#include <RBDdimmer.h>

void setup() {
// put your setup code here, to run once:


void loop() {
// put your main code here, to run repeatedly:


WInterrupts.c.o (symbol from plugin): In function `attachInterrupt ':

(.text + 0x0): multiple definition of `__vector_1 ’

libraries EBDDimmer-master will have RBDmcuAVR.cpp.o (symbol from plugin) :(. text + 0x0): first defined here

collect2.exe: error: ld returned 1 exit status

exit status 1
Error compiling for Arduino / Genuino Uno card.

Both libraries are trying to use the same interrupt which is not possible

how can i solve the problem i tried to check both libraries but i don't understand anything excuse my ignorance

There may be a way not to use one of the libraries depending on what you want to do, use a different library or try modifying one of them.

What exactly are you trying to do ?

The library "EBDDimmer-master" is trying to use an interrupt vector that the Arduino core already uses (for attachInterrupt()). I guess it is not an Arduino library.
