Which repository to clone ?

[srishti sharma]

Hey,
I am an absolute newbie , I tried to clone greg kroah-hartman's
staging tree repository , somehow I was not able to boot in the kernel
I built .

Also, Does this command below give me the latest kernel code ?

I have tried to clone another repository using the command below

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git


while building with this , I had to install gcc plugin-dev . I don't
understand why ?
I didn't have to do it last time I built the kernel

Regards

Thanks for replying ,
Does the one I cloned give me 2.6 kernel version , is this not being
developed now ?
Also why did I need to use gcc plugin-devs ?

Yes, the one you tried is the (very old) 2.6 kernel. I dont know why you 
would have to install the plugin-devs. Which distro are you running?

You may use this link,
https://www.kernel.org/doc/man-pages/linux-next.html
In summary, first you clone main upstream tree then add linux-next tree.
Whenever you want to create a patch, create a topic branch from the
latest next-* tag.

Also my compiler is saying things like , cyclomatic complexity
followed by (i think) the parts it is compiling like driver names .
Also it has been two hours since it started compiling and it isn't
done yet . Is it because I ran $make instead $make -jx ? It was by
mistake .

My advice is that
1) Clone your repo using the link that I have sent to you.
2) You have said that you are an absolute beginner, so create your topic
branch from upstream kernel master branch.
3)Last but not least, please read Linux Kernel In Nutshell(LKN)

If you want to complile for arm, an example,
ARCH=arm CROSS_COMPILE=arm-linux-gnueabli- make distclean
ARCH=arm CROSS_COMPILE=arm-linux-gnueabli- make omap2plus_defconfig
ARCH=arm CROSS_COMPILE=arm-linux-gnueabli- make zImage dtbs

This zImage can be run on BeagleBone Black.

Sorry, it is gnueabi. arm-linux-gnueabi- is prefix of arm gcc compiler
installed on your system.

Because you must have enabled the gcc-plugin kernel build options.
Disable them if you do not wish to do this.
