ARM 926ej-S core를 위한 크로스 툴체인이다. 이 크로스 툴체인을 리눅스 데스크탑 환경에 의존적이게 만들었기때문에,
이 크로스 툴체인을 정상적으로 이용하려면 페도라 코어 6/7/8/9 및 CentOS 5.X 를 설치해야 한다.
- 테스트된 타겟보드: OMAP 5912 OSK (arm926ej-S) , FreeScale i.MX27(arm926ej-S) , Android Emulator(GoldFish)

Kandroid Toolchain ver 1.1.2.4 (July 02, 2008)
-------------------------------------------------------
1. Definition
"Kandroid Toolchain" is Development tool for compiling android kernel and system libraries
(ex: webkit, sqlite, libc, Etc) in android softwar stack for kandroid.org members.
This Toolchain is a collection of software tools used for the development and building of software
for a particular target architecture like ARM.
2. Goal
-Easy to Use (Just decompress using tar command)
-EABI Support ( ABI Compatibility )
-Support various compiler like gcc , g++
-The recent opensource version to reduce gap between versions.
-NPTL Thread Model (Kernel Requirement : FUTEX , EPOLL)
-Non Floating Point is default setting(Soft-Float).
-Little Endian is default setting.
-Support MPFR for multiple-precision floating-point computations with correct rounding.
-Include GDB, Strace for Fast Debugging and Tuning
3. Package Version information
