[Question]-Make a System Call Linux Kernel 3

[resid3nt]

Hello,
New member here:)

I need to make a System Call like this article here which I followed

Code: [Select]

https://arvindsraj.wordpress.com/2012/10/05/adding-hello-world-system-call-to-linux/
I downloaded Linux Kernel 3.2.0 and I have done the modifications are being said in the above article

According to this I am trying to install the Kernel with : sudo make modules_install

Code: [Select]

http://www.howopensource.com/2011/08/how-to-compile-and-install-linux-kernel-3-0-in-ubuntu-11-04-10-10-and-10-04/
I have this error:cp: cannot stat ' /usr/src/linux-3.2.0/modules.builtin': NO such file directory
make: ***[_modinst_] Error 1

I installed module but again this error

Something more:
In the 1st article

Now, in the root directory of the kernel sources, create a directory named hello and in it, a file hello.c with the following content:

#include <linux/kernel.h> asmlinkage long sys_hello(void) { printk("Hello world\n"); return 0; } 

printk is similar to printf function of C but writes to the kernel log instead of the screen. asmlinkage is a key word used to indicate that all parameters of the function(here none of course ) would be available on the stack.

The root directory of the kernel sources is the linux-3.2.0 Folder??

I had never any experience with kernel if you know any book to get some more explanation please write

Thanks in advance

You need to compile the kernel and modules first.

Code: [Select]

$ make # Compile the kernel
$ make modules # Compile the modules
$ make install # Install the kernel (just moves it to /boot and stuff)
$ make modules_install # Install the modules

ok thanks a lot

I did make and make modules

I will try all of them again

They finished

output error:

ld: cannot find bloc/helloworld: No such file or directory
make: ***[vmlinux.o] Error 1

---
My system call is helloworld

[resid3nt]

I did all the process from the begining

I donwloaded the kernel 3.2.0
 *linux_3.2.0-83.120.diff.gz
 *linux_3.2.0.orig.tar.gz
 *linux_3.2.0-83.12.0.dsc
 
 I had combined all these in linux-3.2 Folder
 
 I had inserted my System Call

Code: [Select]

 According to this guide I try to Build the kernel and then Install it

Code: [Select]

https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
 When i write fakeroot debian/rules clean an erro appears :
 
 /usr/bin/fakeroot: line 178: debian/rules: no such a file or directory
 
 Thanks
 
 Using Ubuntu 12.04 64bit kernel 3.10

I recommend you to compile it the Debian way:

Code: [Select]

make -jX deb-pkgInstead of "X" put your processor's cores numbers plus one, so if you have 2 cores:

Code: [Select]

make -j3 deb-pkgAt this point you will your .deb packages on the folder on top of your current, so if you want to install all the packages:

Code: [Select]

dpkg -i ../*.deb # don't use it, CHECK ALL THE PACKAGES YOU INSTALLIn this way all the aspects about the kernel images will be managed by the system's packet manager, so you can install / install it really safely, without touching your config files.
You can also compile the kernel the old fashioned way:

Code: [Select]

make -jX && make modules_installAnd then proceed with the manual installation, but if you are new to the kernel world, I really don't suggest you to do it, stick it with Debian!

Best luck,

there are nice but quite outdated tuts on kernel building here

http://docs.slackware.com/howtos:slackware_admin:kernelbuilding
http://docs.slackware.com/slackbook:linux_kernel
http://docs.slackware.com/howtos:slackware_admin:building_the_linux_kernel_using_git_repository

however yesterday I got drunk and compiled my kernel now i have broken slackware. Trying to do that properly this time.
