EDIT: sorry, a clean build fixed it. Using the dev branch works OK with the latest piaware-git (+ Itcl patch).

I cannot compile the dev branch on armv7h. Compilation hangs at:

cc -D_FORTIFY_SOURCE=2 -DMODES_DUMP1090_VERSION=\"\" -DMODES_DUMP1090_VARIANT=\"dump1090-fa\" -DENABLE_RTLSDR -DENABLE_BLADERF -march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16 -O2 -pipe -fstack-protector-strong -fno-plt -std=c11 -O2 -g -Wall -Werror -W -D_DEFAULT_SOURCE -I/usr/include/ -I/usr/include/libusb-1.0  -I/usr/include/  -c mode_ac.c -o mode_ac.o

@anish thanks for fixing it! Sorry to keep bothering you, but I also just realized: since you changed piaware-git to use the dev branch as its source, do you think you could do the same for this package? I noticed that piaware was complaining about a version mismatch in its logs, and editing this PKGBUILD to point to the dev branch fixed it.

@panissupraomnia I was thinking about that but most of the definitions in show_config() are wrong that way. For now that is a better fix, updated

Yeah, this doesn't work on aarch64. Due to the pre-processor conditional, freq doesn't get defined, so the build errors out in that same function as before. Since you've updated the dependency on bladerf to be >=2.0.2, is there any reason why you even need the architecture-dependent definitions? I would think that just replacing it with the bladerf_frequency typedef would work across platforms (and be more clear).

This should be working for everyone now, but I was only able to test arm6/arm7 & x86_64. Please let me know if you're on a different arm processor and it does not work for you

You'd probably figure this out pretty quickly, but this is the same issue that @kikoloche posted about in February, and I believe my solution is correct (it's been working fine for me at least). Unfortunately the fix hasn't made it into upstream because they need to maintain compatibility with Debian Jessie, which made the PR to fix it stall (see https://github.com/flightaware/dump1090/pull/22).

Thanks for the heads up, I'll get to this tonight

Thank you for the great PKGBUILD. It seems that this version fails to build because of the bladerf dependency: not using bladerf but having this version bladerf 2.0.2-1

sdr_bladerf.c: In function ‘show_config’: sdr_bladerf.c:116:76: error: passing argument 3 of ‘bladerf_get_frequency’ from incompatible pointer type [-Werror=incompatible-pointer-types] (status = bladerf_get_frequency(BladeRF.device, BLADERF_MODULE_RX, &freq)) < 0 || ^~~~~ In file included from sdr_bladerf.c:23: /usr/include/libbladeRF.h:1162:56: note: expected ‘bladerf_frequency ’ {aka ‘long unsigned int ’} but argument is of type ‘unsigned int ’ bladerf_frequency frequency); ~~~~~~~~~~~~~~~~~~~^~~~~~~~~ cc1: all warnings being treated as errors make: *** [Makefile:41: sdr_bladerf.o] Error 1

Thanks. It works again with bladerf 2.0.2 version instaled

Also, just to note, I can confirm that this builds successfully on aarch64, if you'd like to add that to the arch list.
