[OpenEmbedded] 如此简单运行FreeDoom

图片如下

下面是环境设置脚本：
env.sh:

1. #!/bin/sh
2. # if do not unset this, you may meet configure error when configure glibc
3. # it says this can not contains current directory
4. unset LD_LIBRARY_PATH
5. export OEDIR=$PWD
6. export LOCALDIR=$PWD/dirk
7. # export the bb file paths
8. export BBPATH=$OEDIR/build:$OEDIR/openembedded:$LOCALDIR

复制代码

下面是我的Image文件:
cch@srdgame:~/embedded/dev$ vi dirk/packages/images/dirk-image.bb

1. #Dirk X11 image
2. ANGSTROM_EXTRA_INSTALL ?= ""
3. XSERVER ?= "xserver-kdrive-fbdev"
4. export IMAGE_BASENAME = "dirk-image"
5. DEPENDS = "task-base"
6. IMAGE_INSTALL = "\

15. IMAGE_PREPROCESS_COMMAND = "create_etc_timestamp"
16. #zap root password for release images
17. ROOTFS_POSTPROCESS_COMMAND += '${@base_conditional("DISTRO_TYPE", "release", "zap_root_password; ", "",d)}'
18. inherit image

具体如何使用OpenEmbedded构建你自己的潜入式操作系统，请参看OE的官方Wiki.  我就不多废话了。
