Error installing nexmon csi

[ayyp1]

root@raspberrypi:/home/ayyp/nexmon/patches/bcm43455c0/7_45_189/nexmon_csi# sudo make
Makefile:3: /firmwares/bcm43455c0/7_45_189/definitions.mk: No such file or directory
make: *** No rule to make target '/firmwares/bcm43455c0/7_45_189/definitions.mk'. Stop.

what should I do ?

The nexmon framework depends on a specific environment that gets set when running source setup_env.sh. When you execute make with sudo, you are changing to a different environment due to sudo. Due to that, nexmon does no longer run as expected. Either run make without sudo or pass your current environment to it by using sudo -E.

As you are trying to compile for the WiFi chip that can be found on Raspberry Pis, I assume that you are trying to do it on a Raspberry Pi.
The output you posted tells that you are missing libmpfr.so.4.
Follow the README on how to setup nexmon on a Raspberry Pi: http://github.com/seemoo-lab/nexmon?tab=readme-ov-file#build-patches-for-bcm43430a1-on-the-rpi3zero-w-or-bcm434355c0-on-the-rpi3rpi4-or-bcm43436b0-on-the-rpi-zero-2w-using-raspb
It tells you what to do.
