혼자왔니

공식사이트를 보고 나름대로 해석해 보았습니다.

EGLS 는 OpenGL ES, OpenVG , 윈도우 시스템과 같은 프로그램을 인터페이스 하기위한 Khronos rendering API 이다. 그래픽 컨텍스트 관리 ,  surface/buffer binding , 렌더링 동기화와 높은 동작이 가능, accelerated , 2D  와3D  섞어서 렌더링이 가능하다.  또한 상호 정보교환이 가능하다 (ex : 비디오 시스템이 동작중에 OpenMAX AL and a GPU running OpenGL ES)

다양한 운영체제에 동작이 가능하며, Xlib or GDI 같은 다른 기본 렌더링을 API 로 제공한다.

Bitbake 설치

git clone git://git.openembedded.org/bitbake

환경변수 설정후  export PATH: XXX :$PATH

http://www.yoctoproject.org/docs/2.0/bitbake-user-manual/bitbake-user-manual.html#hello-world-example

레퍼런스 매뉴얼을 참고했다.

A.4. The Hello World Example

홈디렉토리에 폴더를 생성하고 실행

1.  RunBitbake

li@li:~$ mkdir BB

li@li:~$ cd BB

li@li:~/BB$ ls

li@li:~/BB$ bitbake

The BBPATH variable is not set and bitbake did not find a conf/bblayers.conf file in the expected location.

Maybe you accidentally invoked bitbake from the wrong directory?

     $ BBPATH="projectdirectory"  <--- 프로젝트 디렉토리
     $ export BBPATH

다시 bitbake를 실행한다.

4. base.bbclass 파일에 다음 추가 addtask build

The minimal task that BitBake runs is the do_build task. This is all the example needs in order to build the project. Of course, the base.bbclass can have much more depending on which build environments BitBake is supporting. For more information on the base.bbclass file, you can look at http://hambedded.org/blog/2012/11/24/from-bitbake-hello-world-to-an-image/#tasks.

5. Run Bitbake : Log

Nothing to do.  Use 'bitbake world' to build everything, or run 'bitbake --help' for usage information.

$ cd $HOME
$ mkdir mylayer
$ cd mylayer
$ mkdir conf

 Nothing to do.  Use 'bitbake world' to build everything,
