Usage:

## Converting sparse flashing system.img from flashing android sparse img to ext4 img

$ simg2img system.img system.raw.img
## or all parts of sparse img
$ simg2img system.img* system.raw.img

## Mounting ext4 img for edit

$ mkdir system_mnt
$ mount -t ext4 -o loop system.raw.img system_mnt

## Creating new android sparse img for flashing (android 2.3.6-4.2)

$ mkuserimg.sh -s system_mnt system_new.img ext4 ./system [size partition MB for example 1024M]
## or
$ make_ext4fs -s -l 1024M system_new.img system_mnt

more

$ mkuserimg.sh -s system system.img ext4 /system [size partition MB for example 1024M] file_contexts

## Converting ext4 img to sparse img for flashing (android 4.3-etc)

$ ext2simg -v system.raw.img system_new.img

## Changing sparse img header size from 28bit to 32bit (for Samsung Exynos Octa)

$ sgs4ext4fs --bloat system_new.img system_32bit.img

## Remove Moto extra header... (for Motorola G-series, making after unsparse img)

$ mv system.raw.img system.moto.img
$ dd if=system.moto.img of=system.raw.img ibs=131072 skip=1

Some headers missed. I am using Ubintu 12.04 and installed zlib1g-dev for compiling zlib_host. But make_ext4fs don't compiling:

Building make_ext4fs...

Well you has two ways:
This http://www.zlib.net/
or

make clean
make clear
./configure
cd ./zlib/src
./configure
make
sudo make install
cd ../..
make clean
make

As I said I have compiled zlib_host by installing zlib1g-dev. Compile broken at ext4fs - maybe there are no extra headers for ext4fs, such as for struct stat.

1. zlib1g-dev - не входит в состав zlib
2. у меня установлена Ubuntu 13.10 amd64 gcc 4.8
поэтому - не могу точно ответить по 12.04

gt.

1. zlib1g-dev - not part of zlib
2. I have installed Ubuntu 13.10 amd64 gcc 4.8
so - I can not exactly answer to 12.04

Assembly must be done on 64 bit OS. Only installing zlib-1.2.8
View attachment zlib-1.2.8.tar.gz
And the following packages

sudo apt-get update
sudo apt-get install ia32-libs

gcc 4.8 can be set separately

hi sir. may i ask you to update op with more explanation of what can do your tool?
i understood that it unpack and repack boot.img and compile binaries...
and after that i am wondering what more? what for?
i use kernel tool master to unpack and repack boot.img...
what is the diffeence and the purpose of you tools?
thank you...
i know i miss of knowledge so that is why i ask.

Old binary do not work with newer versions of android

Old binary do not work with newer versions of android

does that tool can take binaries from one kernel to port it to another?

The way is not into repacking boot image, but different version of android has different parametrs of FS. Example android 4.3 ext4 FS has support SELinux, but 4.1 and older hasn't

I still don't get the purpose of these tools. I've been running Gentoo Linux as my primary OS for a dozen years, all the tools I need to compile kernels, create boot images, ramdisks, initrds, extract and manipulate from already created images, are already installed on my system by default. Why would I need these too? Are these supposed to be time-savers? Shortcuts? I still don't understand.

Well, how I can see, you're HTC user, and maybe this utilities isn't you needs, because htc don't use sparse images, and different header block size in self rom. But samsung, sony, asus and different brands using it...

why is this error?

Building mkbootimg...

why is this error?

cd zlib/src
make clean
./configure
make
sudo make install

and try again...
