Hi Miegl,
with Raspberry Pi OS 11 (Bullseye) and
Linux cptech 6.1.44-v8+ #1670 SMP PREEMPT Wed Aug 9 11:56:17 BST 2023 aarch64 GNU/Linux, after "make":
gcc -Wall -Wno-multichar -std=gnu99 -c -g -O1 -march=armv7-a -mtune=arm1176jzf-s -mfloat-abi=hard -mfpu=vfp -ffast-math -DRASPI=4 rds.c
gcc: error: unrecognized command-line option ‘-mfloat-abi=hard’
gcc: error: unrecognized command-line option ‘-mfpu=vfp’
make: *** [Makefile:36: rds.o] Error 1
Is there a solution...?
Thanks for reply!

I had the same issue when attempting to build on a Pi4 using 64 bit OS.

I was able to build by replacing the makefile with the one from this pull request:
