test_txrx_hwloop.c / bladeRF build error on Raspberry Pi 4 B (bullseye 32bit, bookworm 64 bit)

[denisvasyukov]

I have the following error during the build:

/home/pi/bladeRF/host/libraries/libbladeRF_test/test_timestamps/src/test_txrx_hwloop.c: In function ‘main’: /home/pi/bladeRF/host/libraries/libbladeRF_test/test_timestamps/src/test_txrx_hwloop.c:104:74: error: comparison is always true due to limited range of data type [-Werror=type-limits] 104 | while ((c = getopt_long(argc, argv, optstr, long_options, &opt_ind)) >= 0) { | ^~ cc1: all warnings being treated as errors make[2]: *** [libraries/libbladeRF_test/test_timestamps/CMakeFiles/libbladeRF_test_txrx_hwloop.dir/build.make:82: libraries/libbladeRF_test/test_timestamps/CMakeFiles/libbladeRF_test_txrx_hwloop.dir/src/test_txrx_hwloop.c.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:1378: libraries/libbladeRF_test/test_timestamps/CMakeFiles/libbladeRF_test_txrx_hwloop.dir/all] Error 2 make: *** [Makefile:149: all] Error 2

this happens for all the last commits since 31 May 2023 at least.
One commit that still works is from 17 Oct 2022.
Is there a solution for it?

Hi, this is caused by -Werror=type-limits added automatically by -Wextra.
I solved this by removing -Wextra from libraries/libbladeRF_test/test_timestamps/CMakeFiles/libbladeRF_test_txrx_hwloop.dir/flags.make file
