linux-headers problem compiling drivers on RasPI 2 w/ Kali 2.01

[ovosodo]

Hi all, to natively build wifi drivers and other nice things I need the linux-headers matching the current kernel.
Kali 2.01 ARM for RasPI 2 uses kernel 3.18.16-v7 but repos include 4.0.0-kali1-armmp
Someone already found some quick workaround?
Thanks,
OS

would like to know this as well

Thanks !

Due to the way the image is created, there's an issue with the lib/modules/$(uname -r)/{build,source} directories - they point to my home directory instead of the place in the actual system.

What you want to do is 'rm /lib/modules/$(uname -r)/{build,source}'; ln -s /usr/src/kernel /lib/modules/$(uname -r)/{build,source}

Great steev, I didn't notice wrong $(uname -r)/{build,source} symlinks.

Well, this is a step forward, but still doesn't solve my driver build issue, maybe linux-headers aren't enough:

root@kali:~/Downloads# cd rt8192cu/
root@kali:~/Downloads/rt8192cu# make

try with ARCH=arm - armv7l is an Arch Linux thing.

That said - what's wrong with the rtl8192cu driver that's already part of the kernel?

Thanks steev, ARCH=arm solves the problem, however none of the 8188cus git repos I tryed builds successfully on Rpi Kali2, so I gived up on this way and found an alternative solution which doesn't require builds or linux-headers.
I'm sure having solved the linux-headers issue will be useful anyway sooner or later

My goal is to build some headless, cableless, portable Rpi2 using Kali2. This seems a hot topic, but none of the solutions I found are satisfying.
I would like to use my 3G tablet or smartphone to connect to the Rpi using ssh, while being able to use the 3G internet connection both from the tablet/phone and the Rpi.

As a poor man temporary solution, I activated an ad-hoc connection on the Rpi, it's simple but has security and connectivity problems.
In the next spare time I will activate on the Rpi a wpa2 client which connects to the mobile hotspot, so I will solve my goals of ssh access to Rpi and internet connectivity on both devices.

Maybe it's better to open a new topic on this.
Thank you,
OS

I would suggest using a better wifi card for that case. the rtl8188 cards are **** for anything more than just connecting to a wireless network.

@ovosodo Where is the solution (though it is marked as solved) ??

I recently installed Kali 2.0.1 on RPi2 which has kernel version 3.18.16-v7.
I need the linux-headers to 'make' the wifi dongle drivers.
But the original repos have headers for kernel 4+.

Alternatively, I found a repo for headers here
http://www.niksula.hut.fi/~mhiienka/...x-headers-rpi/
But unable to install due to unmet dependencies.

Please help @g0tmi1k

[steev]

The 2.0 images have the kernel sources available in /usr/src/kernel - you need to go into /lib/modules/3.18.16-v7/ and correct the build and source symlinks to point to /usr/src/kernel

The first response from me in the thread says as much (thus solved)

[buxbud]

Thanks for the clarification @steev
My doubt was that @ovosodo still reports errors during compiling.
Is that a specific bug for the chipset wifi cards ?

So as per your post (#3) the linux-header modules/files/dependencies for 'make' are already available but is pointing to the wrong path.
The two commands to be run to correct this are

rm /lib/modules/$(uname -r)/{build,source}

ln -s /usr/src/kernel /lib/modules/$(uname -r)/{build,source}

[steev]

He's saying that none of the drivers that he found work - honestly, I have no idea what repos he's tried/trying, and that card is a piece of ****. There's a reason why people don't recommend those cards over something with an atheros or rt3070 chipset in them.

Sorry for my absence.
The repo I tried was https://github.com/dz0ny/rt8192cu.git
The focus of the thread (linux-headers problem) was solved thanks to steev's hint (wrong symlinks in the Kali image).
As I said I turned to a workaround solution which doesn't require a wifi driver rebuild, so I didn't solve the RTL81* specific wifi driver rebuild issue.
I have a dozen of different RTL8188* and RTL8192* adapters laying around. They are nice, small and low-power. However due to chipset and antenna limitations the only acceptable use I found is on a portable headless Rpi2, to connect nearby to a tethering smartphone.

Still no luck for me.
Here is what I did. Trying to compile drivers for MT7601U chipset wifi usb dongle on Kali2.0.1 on RPi2

Hi!
I have totally same problem, but unfortunately i can't solve it.
After i type:

rm /lib/modules/$(uname -r)/{build,source}
ln -s /usr/src/kernel /lib/modules/$(uname -r)/{build,source}
apt-get install linux-headers-$(uname -r)

i get:
E: Unable to locate package linux-headers-3.18.16-v7
E: couldn't find any package by regex 'linux-headers-3.18.16-v7'

after reboot:
uname -r
3.18.16-v7

Could you please help me in the case?
