Buildroot for ARM
Buildroot 是一套用來打造 Embedded Linux System工具, 可以在此平台上編譯產生不同系統的Root File System, Toolchain。
打造工作環境：Embedded Linux for ARM
1. 下載Buildroot
下載檔案：buildroot-2012.11.1.tar.bz2 / buildroot-2012.11.1.tar.gz
2. 解壓縮
＄tar zxvf buildroot-2012.11.1.tar.gz
2.1安裝其它package
EX: [GM8138S install package: 64bit ubuntu]
$ sudo apt-get install g++
$ sudo apt-get install lib32z1-dev //compression library - 32 bit runtime
$ sudo apt-get install lib32z1
$ sudo apt-get install libncurses5-dev //shared libraries for terminal handling
$ sudo apt-get install libncurses5
$ sudo apt-get install bison //YACC-compatible parser generator - development library
$ sudo apt-get install flex //A fast lexical analyzer generator.
$ sudo apt-get install texinfo //Documentation system for on-line information and printed output
EX: [GM8138S install package: 32bit ubuntu]
$ sudo apt-get install g++
$ sudo apt-get install bison
$ sudo apt-get install flex
$ sudo apt-get install texinfo
3. 設定組態
$ make menuconfig
#組態選擇
(1)選擇 arm
Target Architecture (arm) --->
(2)選擇 generic_arm
Target Architecture Variant (generic_arm) --->
(3)選擇 EABI
Target ABI (EABI) --->
ABI: application binary interface
OABI: old application binary interface
(4)選擇 Linux kernel 3.2 / busybox 1.19.x/ binutils 2.21.1 / uClibc 0.9.32.x /gcc 4.6.4
$ make
$ ls -al output/ //編譯成功輸出於output folder
[Note ***]
