# Build Static Android Platform Tools without GO.

Some days ago, I found an interesting [repository](https://github.com/nmeum/android-tools) about android tools which can be built without GO compiler (check it [here](https://github.com/nmeum/android-tools)). If you're familiar with `adb`, `fastboot`, etc, you know what I'm talking about. It suits me because I have no GO compiler or won't bother to download one because I already have GCC. After firts successful build which result on dynamic linked binaries, I'm curious on building the static linked one. Here is how I did it !

## Preparations

Before we go deep into building stuffs, we need to prepare some stuffs.

- Make sure you have GCC / Clang !
- Satisfy the dependencies, check on the README !
- Make sure you rebuild these package and enable their static option ! Be careful, some these libs will probably mess your system if you don't know what you're doing !

	- abseil-cpp.
	- brotli, use `-DBUILD_SHARED_LIBS=OFF` option.
	- fmt, use `-DBUILD_SHARED_LIBS=OFF` option.
	- lz4.
	- protobuff, use `-DBUILD_SHARED_LIBS=OFF` option.
	- zlib, use and add `--static` option when configure the build.
	- zstd.
	- libusb, use and add `--enable-static` option when configure the build.


## Steps

These are some steps to build static android tools :

1. Get the source code ! You can get it [here](https://github.com/nmeum/android-tools/releases/download/35.0.2/android-tools-35.0.2.tar.xz) for 35.0.2 version. 
1. Modify the CmakeLists.txt file ! Add these line after line contain `project(android-tools)` !


	```
	set(BUILD_SHARED_LIBS OFF)
	set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
	set(CMAKE_EXE_LINKER_FLAGS "-static")
	```

1. Do the regular build as the README suggest !


	```
	$ mkdir build && cd build
	$ cmake ..
	$ make
	```

1. Check if resulted executables are static linked, you can check at build/vendor directory ! 


	```
	$ cd ..
	$ file build/vendor/adb		# adb, for example
	```

	You should get this line : 


	```
	build/vendor/adb: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, with debug_info, not stripped
	```
