i am using raspberry pi zero with pw4n p1 aloa kali linux OS. please tell me the way to fix it.

waiting for your reply

Perhaps try with Raspbian installed? Is the error above when you run sudo make?

[rsaxvc]

Have you seen #104 ? You will need the broadcom libraries installed and available in the linker path.

Here's how I check if those functions exist in the broadcom library on RPiOS:

pi@raspberrypi:~/code/fm_transmitter $ nm /opt/vc/lib/libbcm_host.so  | grep bcm_host_get
00003e14 T bcm_host_get_model_type
00003b1c T bcm_host_get_peripheral_address
00003c38 T bcm_host_get_peripheral_size
00003f0c T bcm_host_get_processor_id
00003d70 T bcm_host_get_sdram_address
pi@raspberrypi:~/code/fm_transmitter $

If this returns similar entries for the bcm_host_ functions, you might try reordering the linker flags like was done in #104
