Cross compile gpsd-3.20.1~dev for arm with buildroot

[Florian Kiera]

Heyo,

I am trying to update the gpsd version for our buildroot and keep running into an error:

/home/florian/Desktop/buildroot-2019.02.8.2/output/host/bin/arm-buildroot-linux-uclibcgnueabihf-ld -o libgps.so.27.0.0 --sysroot=/home/florian/Desktop/buildroot-2019.02.8.2/output/host/arm-buildroot-linux-uclibcgnueabihf/sysroot -pthread -shared -Wl,-Bsymbolic -Wl,-soname=libgps.so.27 ais_json.os bits.os gpsdclient.os gps_maskdump.os gpsutils.os hex.os json.os libgps_core.os libgps_dbus.os libgps_json.os libgps_shm.os libgps_sock.os netlib.os os_compat.os rtcm2_json.os rtcm3_json.os shared_json.os timespec_str.os libgpsmm.os -L. -L/home/florian/Desktop/buildroot-2019.02.8.2/output/host/arm-buildroot-linux-uclibcgnueabihf/sysroot/usr/lib -L/home/florian/Desktop/buildroot-2019.02.8.2/output/host/arm-buildroot-linux-uclibcgnueabihf/sysroot/usr/lib -lstdc++ -lrt -lnsl -lm -ldbus-1 -ldbus-1 -lrt -lnsl

I already know buildroot can be tricky sometimes. But how it comes that scons/gpsd is using the arm-buildroot-linux-uclibcgnueabihf-ld to compile the libgps.so while on x86_64 it uses the g++? It also used the g++ when compiling with the older version 3.18 (line 131 of compile-3.18_success.txt).

uclibcgnueabihf-ld isn't used a single time in the 3.18 cross compilation, why so in the 3.20 cross compilation? Its neither used in the compilation for x86_64.

Regards Florian
