make dkms_install does not work (Error 1) #802

Aholicknight commented 3 years ago

I am running the latest version of Kali Linux and trying to install the driver. I enter the command sudo make dkms_install and it shows this as the output.

mkdir -p /usr/src/8812au-5.6.4.2_35491.20191025
cp -r * /usr/src/8812au-5.6.4.2_35491.20191025

Error! echo
Your kernel headers for kernel 5.9.0-kali1-amd64 cannot be found at
/lib/modules/5.9.0-kali1-amd64/build or /lib/modules/5.9.0-kali1-amd64/source.
You can use the --kernelsourcedir option to tell DKMS where it's located.
make: *** [Makefile:2306: dkms_install] Error 1

How can I fix this? The Kali Version I am currently using is 2020.4

Thank you!

@giangiluca This works thank you.

Aholicknight commented 3 years ago

I will keep this issue open as this problem still remains with the repo.

danieletorelli commented 3 years ago

Happened to me on RPI 4 but for a different reason: it seems like the changes introduced by https://github.com/aircrack-ng/rtl8812au/pull/769 are resulting in a build failure gcc: error: -mfloat-abi=soft and -mfloat-abi=hard may not be used together.

@danieletorelli I can confirm that the makefile if broken due #769

arm kernels are build with -msoft-float

https://github.com/torvalds/linux/blob/master/arch/arm/Makefile#L128

So -mfloat-abi=hard not works on arm builds with kernels compiled with arm 32b (works fine on arm64)

Will work on that on the weekend.

ping @pprindeville

pprindeville commented 3 years ago

@CGarces What are you suggesting?

What would probably be cleanest is something like:

...
else ifeq ($(ARCH), arm)
# Raspbian kernel is with soft-float.
# 'softfp' allows FP instructions, but no FP on function call interfaces
ifeq ($(CONFIG_PLATFORM_ARM_RPI), y)
EXTRA_CFLAGS += -mfloat-abi=softfp
else ifeq ($(ARCH), arm64)
EXTRA_CFLAGS += -mfloat-abi=hard
else
$(error ARCH: need architecture explicitly set)
endif
endif

Hi @pprindeville Please review #814 and continue the discussion on that PR. I open to any ideas my knowledge is limited on this topic.

danieletorelli commented 3 years ago

Thanks for your fix @CGarces. I can confirm that now works as expected.

maybe consider closing the issue since nothing new occured for some months :)
