안드로이드 커널 및 시스템 라이브러리 (예: libc , webkit , sqlite , etc), 기존 C/++ 코드 재사용을 위한 처지에
있는 분들이 안드로이드용 툴체인을 반드시 사용해야 되는 경우에 해당될것으로 알고 있습니다. 아래의 툴체인을
사용하시면서 버그 및 문제 사항들을 댓글로 올려 주시면 신속히 조치 및 의견을 드리겠습니다.
제작된 본 툴체인으로 arm1136jf-S core이상의 타겟보드에서 테스트를 마쳤습니다.
( * 테스트된 타겟보드: armadillo-500-arm1136jf-s , omap2430osk , logicpd-omap3430-Cortex-A8 , omap2evm ,
HTC-Kaiser , Nokia-N810, SMDK 6400 , SMDK 6410 , SMDK 6440 , S3C100/110 )
Kandroid Toolchain ver 1.1.2.1 (May 30, 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++ , gcj
-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

7. Bug Report or Contacts
8. Ref
-gcc 4.3 depends on mpfr>=2.3.1
9. Todo
- Support ltrace for glibc api and user libraries tracing
- Extensible cross languages like ada , object C ,object C++
- --enable-thread-safe option problem of MPFR configure command.
