Linux下poky编译2
2、进入pinky目录输入
source poky-init-build-env
3、修改build/conf/local.conf ，主要是修改MACHINE,我用samsung的ARM，所以选了fic-gta01，也就是OPENMOKO的平台
4、决定编译什么样子的目标，poky 可以编译好多种image，按照手册上的描述有这些:
-
poky-image-minimal - A small image, just enough to allow a device to boot,
-
poky-image-base - console only image with full support of target device hardware,
-
poky-image-core - X11 image with simple apps like terminal, editor and file manager
-
poky-image-sato - X11 image with Sato theme and Pimlico applications. Also contains terminal, editor and file manager.
-
poky-image-sdk - X11 image like poky-image-sato but also include native toolchain and libraries needed to build applications on the device itself. Also includes testing and profiling tools and debug symbols.
-
meta-toolchain - This generates a tarball containing a standalone toolchain which can be used externally to Poky. It is self contained and unpacks to the
/usr/local/pokydirectory. It also contains a copy of QEMU and the scripts neccessary to run poky QEMU images. -
meta-toolchain-sdk - This includes everything in meta-toolchain but also includes development headers and libraries forming a complete standalone SDK. See the Developing using the Poky SDK and Developing using the Anjuta Plugin sections for more information.
我因为要首先调试硬件和驱动，所以暂时编译了minimal。
bitbake poky-image-minimal
6、在Linux下会出现mmap: Permission denied错误,解决办法是输入
su
echo 4096 > /proc/sys/vm/mmap_min_addr
7、提示你没有安装psyco的话，在Linux里只要sudo apt-get install python-psyco 就可以了。
8、在整个image编译完成后，如果修改了某个包的代码，要重新编译整个image，可以删除build/tmp/stamps里面相应的文件，然后重新bitbake <image-name> 即可。
9、如果只需要重新编译某个包，而不需要重新生成一遍image，可以对其进行单独的编译，比如如果要编译修改后的内核，可以输入：
bitbake virtual/kernel -c compile -f (-c 指定了要执行什么命令，-f则表示不管stamps里的标志强制执行）
