Cross compilation error in Lora_gateway

[George-Ng2020]

Hi

Anybody know how to fix this issue? I clean all using "make clean all" and rebuild the following error appeared

george@george-VirtualBox:/lora_gateway$ make ARM=arm CROSS_COMPILE=arm-linux-gnueabihf-
make all -e -C libloragw

Perhaps loragw_spi.o did not get compiled correctly for you, since some symbols are missing from it. If you have not done it, perhaps check that it is getting compiled successfully; when you do make clean ensure that loragw_spi.o is deleted and recompiled when you do make.
