Hello, I'm trying to compile this 8723du.ko module on sebanc brunch chromeos build using chromebrew, but it throws error about "stack_chk_guard" :

According to some of my friend, this is because of the gcc10 that chromebrew use and suggest to add "-fstack-protector-all" on Makefile, but unfortunately I don't know how or where I have to put that cflag. Can someone help me, where I have to put this cflag on Makefile please ? I tried with EXTRA_CFLAGS += -fstack-protector-all on the beginning of Makefile but it throws the same error.

With the same hardware but on ubuntu, this rtl8723du driver was compiled and runs very good without a problem.

Thank you very much in advance, and really appreciate this repo.
