 Posted: Mon Aug 20, 2018 12:32 pm Post subject: [Solved] - Compiling external driver for kernel |
 |
|
Hi,
I have an TP-LINK T4U V2 wifi adapter installed successfully. I'm at the point I would like to update the kernel, using the linux-4.14.63-gentoo-r1 instead of 4.14.61-gentoo. Accodring to the driver description I should log in into the directory and run make clean, make, make install and everything is fine. It is not.
This is the output I get:
| Code: |
localhost ~/rtl8812AU_8821AU_linux # cd /root/rtl8812AU_8821AU_linux/
localhost ~/rtl8812AU_8821AU_linux # make clean
make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/4.14.61-gentoo/build M=/root/rtl8812AU_8821AU_linux clean
make[1]: *** /lib/modules/4.14.61-gentoo/build: No such file or directory. Stop.
make: *** [Makefile:1605: clean] Error 2
localhost ~/rtl8812AU_8821AU_linux # make
make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/4.14.61-gentoo/build M=/root/rtl8812AU_8821AU_linux modules
make[1]: *** /lib/modules/4.14.61-gentoo/build: No such file or directory. Stop.
make: *** [Makefile:1584: modules] Error 2
localhost ~/rtl8812AU_8821AU_linux #
|
What I did so far to workaround this issue:
- set the kernel version to the desired version:
| Code: |
localhost ~/rtl8812AU_8821AU_linux # eselect kernel list
Available kernel symlink targets:
[1] linux-4.14.63-gentoo-r1 *
localhost ~/rtl8812AU_8821AU_linux #
|
deleted the previous kernel directory in /usr/src
| Code: |
localhost ~/rtl8812AU_8821AU_linux # ls -l /usr/src/
total 4
lrwxrwxrwx 1 root root 23 Aug 20 15:35 linux -> linux-4.14.63-gentoo-r1
drwxr-xr-x 26 root root 4096 Aug 20 15:50 linux-4.14.63-gentoo-r1
localhost ~/rtl8812AU_8821AU_linux #
|
deleted the driver directory and fetched from github again, my aim doing this was that, every modified file will be deleted. Result: the same, the source code still wants to go to the old kernel directory.
| Code: | localhost ~/rtl8812AU_8821AU_linux # make -d clean
|
Output is here.
My questions:
- does make cache the path to the kernel values?
- where can I find them?
- how can I delete them if make clean does not work?

sayusi,
| Code: | | make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/4.14.61-gentoo/build M=/root/rtl8812AU_8821AU_linux clean |
Is it trying to build against the running kernel?
What does tell?

It uses still the old kernel.
| Code: |
localhost /home/sayusi # uname -r
4.14.61-gentoo
|
I'm going to reboot it.

The driver source code uses the running kernel for compiling - which is not good as you need access to the machine to compile the driver for the new kernel. It will be a bug ticket for the maintainer. It works fine.
