Building, Configuring kernel for Device Driver Development

Go to /lib/modules/$(uname -r)/build

at this path you should have Makefile (atleast)

if not the follow. http://www.emblogic.com/members/document_view/1258

If you face any issue, error, dough or want any clarifications. Post it here.

I
think this is a linking problem, but I do not know how to fix it. Can
anyone help me?

1. Having System Model - HP Laptop 15-da0xxx

2. Unfortunately, Linux doesn’t include a WiFi driver for my device. I need to disable secure boot and then install these drivers from the link below:

https://we.tl/t-elG77ZwF2X

steps to install :-

sudo apt update && sudo apt install git dkms

cd Downloads

git clone -b extended --single-branch https://github.com/lwfinger/rtlwifi_new.git unofficial

cd rtlwifi_new

/////////////////////////////////////////////////////////////////////////////////////////////////

Turn off secure boot in booting options

install fedora 29 on pc

cp -rf unofficial/ rtlwifi_new/

cd rtlwifi_new/

yum update

reboot

now, install kernel headers and kernel development tools for the current kernel version.

sudo yum install "kernel-devel-uname-r == $(uname -r)"

yum install make

yum install dkms

/////////////////////////////////////////////////////////////////////////////////////////////////

Now, either you can run:

make

sudo make install

/////////////////////////////////////////////////////////////////////////////////////////////////

sudo dkms add ../rtlwifi_new

sudo dkms build rtlwifi-new/0.6

sudo dkms install rtlwifi-new/0.6

sudo modprobe -v rtl8723de ant_sel=2

////////////////////////////////////////////////////////////////////////////////////////////////

3. Now tried to build kernel linux- 5.10.8

By make install got following error

sh ./arch/x86/boot/install.sh 5.10.8 arch/x86/boot/bzImage \ system.map "/boot"

Error! Bad return status for module build on kernel : 5.10.8 (x86_64)

consult /var/lib/dkms/rtlwifi - new/0.6/build/make.log for more information.

4.Got log in make.log file

Didn't able to get wifi drivers during build can someone suggest something ?

I am facing this error after "make install" command :

dracut-install: No SOURCE argument given
Usage: dracut-install -D DESTROOTDIR [-r SYSROOTDIR] [OPTION]... -a SOURCE...
or: dracut-install -D DESTROOTDIR [-r SYSROOTDIR] [OPTION]... SOURCE DEST
or: dracut-install -D DESTROOTDIR [-r SYSROOTDIR] [OPTION]... -m KERNELMODULE [KERNELMODULE …]

Install SOURCE (from rootfs or SYSROOTDIR) to DEST in DESTROOTDIR with all needed dependencies.

KERNELMODULE can have the format:
     <absolute path> with a leading /
     =<kernel subdir>[/<kernel subdir>…] like '=drivers/hid'
     <module name>

Can anyone help me with this

Kernel compression Mode

Note

During kernel compile

Select ZSTD kernel compression.

If you forgot to select this mode. Then bzimage will not be made. So, After make. Install ZSTD ( yum install zstd / dnf install zstd )

then do make again you get your bzimage in 10 min

Then coontinue your install process

How to go about solving the "Failed to load init script" ?

jagjeet.singh9650

I am trying to install kernel and tried to run make command , it just gives an error in between about openssl , that unable to run command openssl , i tried installing openssl-devel , it says already installed but i dont get worksation on boot up.

jagjeet.singh9650

i dont understand when i try to install openssl it says already installed but when i run make command it gives error about openssl

ritde1

Try reinstalling openssl

It's logically correct to compile linux kernel 2.6.38 with gcc 11 but why are there so many errors and warnings?

jagjeet.singh9650

Getting error while compiling linux 2.6.36 , fatal error no such file gcc.h in include/linux/compiler-gcc.h , also I dont see if it is any gcc compiler version issue.

ritde1

Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at kernel/timeconst.pl line 373.

make[1]: *** [/usr/src/linux-2.6.38/kernel/Makefile:140: kernel/timeconst.h] Error 255

make: *** [Makefile:923: kernel] Error 2

I am compiling kernel 2.6.38 with gcc 10.

It gives error #include gcc_header(__GNUC__)

I checked files and folders od kernel. I found that kernel have dependencies of gcc version 3 or version 4.

That's why i am having error.

Now i want to know how to bypass gcc4 dependecies and compile it with gcc10.

rahul

I tried to install gcc 4.9.3 on fedora 33

I got error given below.

How to solve it

cfns.gperf:101:1: error: ‘const char* libc_name_p(const char*, unsigned int)’ redeclared inline with ‘gnu_inline’ attribute
