Database Develop

[Q] [DEV] How to setup development environment?

I want to build a custom kernel and then a native program some sort of daemon.
I want to get original kernel with my modifications.
How to setup build environment?
Which host OS to use for development?
Which compiler?
I found samsung kernel repository in android sources and I've got sources from opensource.samsung.com (froyo + update_JPM + update2)
So which sources to use for my Galaxy S?
Is there are any guides to build kernel and native root level applications (mods, daemons, drivers ...)?

[Q] Can't flash Google Toolchain-compiled kernel

I have an issue with my i9305 as I can't flash Google toolchain-compiled kernel. But it works for me when i flash the same kernel compiled with linaro toolchain. I used Boeffla Kernel 5.1 stable compiled by P$T here http://forum.xda-developers.com/showthread.php?t=2322893&page=54
but failed to flash latest boeffla kernel compiled by lord boeffla (starting 5.1-beta14 reverted back to Google 4.7 toolchain). Does anyone experience the same problem?any ideas?

Yes it Boots.. I tried Preview 4 on my D6503..
If you can, please intergrate TWRP recovery to your kernel. .
then after we get root access, we can hopefully fix the bugs..

How to build custom kernel for Lenovo p1ma40, to support MagiskHide?

Lenovo p1ma40 runs on Android 5.1. And I want to use MagiskHide but am unable to do so, as , "Pre 6.0 kernels are very likely to have no mount ns procfs support, which is required for MagiskHide to work properly. This Linux kernel feature is only required to be added in Android 6.0."
So, as stated at xda forums, we need to rebuild the kernel with the required patch (https://lore.kernel.org/patchwork/patch/217023/). And set
CONFIG_NAMESPACES=y. My question is : 1) How do I patch the kernel source code(pls give exact steps)? 2)How do I flash the modified kernel? 3) do I need to unlock bootloader to do so?
Thanks in advance.....
