wpa_supplicant v2.10 cross-compile for Hi3518ev200

Question

I am trying to cross-compile the latest wpa_supplicant v2.10, and need some advice about the below error.

I compiled the openssl and libnl; however, it fails when compiling the wpa_supplicant

  CC  ../src/drivers/driver_wext.c
  CC  ../src/drivers/drivers.c
  CC  ../src/l2_packet/l2_packet_linux.c
/usr/lib/dbus-1.0/debug-build/lib/libdbus-1.so: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
make: *** [Makefile:1894: wpa_supplicant] Error 1

The dbus-1 of the above step refers to the following libs and cflags locations

root@Debian12:/home/dev/yi-hack-v5/src/wpa/wpa_supplicant-2.10/wpa_supplicant# pkg-config --libs --cflags dbus-1
-I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/debug-build/lib/dbus-1.0/include -L/usr/lib/dbus-1.0/debug-build/lib -ldbus-1 

Below is the library file output.

root@Debian12:/home/dev/yi-hack-v5/src/wpa/wpa_supplicant-2.10/wpa_supplicant# file /usr/lib/dbus-1.0/debug-build/lib/libdbus-1.so.3.32.4

The symlinks:

Any help or direction is appreciated.

I tried Debian 9 with similar effect - I may try https://github.com/drygdryg/wifi_tools_static as per suggestions, but its mainly for Android, so need to adapt for my own platform.

I think I figured it out myself. I had to compile dbus, and expat for the same platform. I followed this guide How to cross-compile D-Bus to ARM?
