配置编译环境(configuration of compifer environment)
准备源码(prepare source code)
准备源码包 (prepare source code package)
1）创建工作目录
create working directory
创建 ~/my-rk3288 作为工作目录
create ~/my-rk3288 as working directory
$ mkdir ~/my-rk3288
My-rk32-ek314build 2.1.1.1.jpg
创建 ~/my-rk3288/02_source 作为源码目录
create ~/my-rk3288/02_source as source code directory
$ mkdir ~/my-rk3288/02_source
My-rk32-ek314build 2.1.1.2.jpg
创建 ~/my-rk3288/03_tools 作为工具目录
create ~/my-rk3288/03_tools as tool directory
$ mkdir ~/my-rk3288/03_tools
My-rk32-ek314build 2.1.1.3.jpg
2）复制源码包到开发主机中
copy source code package to the development host
这一步骤自己采取相应的方式进行。
do it in this step in your own way。
提示：这里将网盘中“02_源码”复制到Linux开发主机的“~/my-rk3288/02_source”，将网盘中“03_工具”复制到Linux开发主机的“~/my-rk3288/03_tools”,将网盘中“01_应用”复制到Linux开发主机的“~/my-rk3288/01_application”。
tip：this step is to copy “02_source code”from network disk to “~/my-rk3288/02_source”in development host, copy “03_tool”to “~/my-rk3288/03_tools, and copy “01_application”to “~/my-rk3288/01_application”。in development host
解压源码包 (decompress source code package)
1）解压u-boot源码和内核源码
decompress u-boot source code and kernel source code
$ cd ~/my-rk3288/02_source
$ tar jxf rk32-myzr_uboot_2014.10_201803028.tar.bz2
$ tar jxf rk32-myzr_kernel_3.10_201803028.tar.bz2
My-rk32-ek314build 2.1.2.1.jpg
2）解压交叉编译工具
decompress cross compiler tool
$ cd ~/my-rk3288/03_tools/
$ tar jxf gcc-arm-eabi-4.6.tar.bz2
My-rk32-ek314build 2.1.2.2.jpg
开发环境配置(development environment configuration)
安装需要的包 (install package needed)
1）更新源列表
list of updated source
$ sudo apt-get update
My-rk32-ek314build 2.2.1.1.jpg
更新完成后如下图所示：
after update,it will look like below：
My-rk32-ek314build 2.2.1.2.jpg
2）安装aptitude包管理工具和ia32-libs
install aptitude package management tool and ia32-libs
提示：如果编译主机的Linux是32位的，可以跳过此步骤。
tips：if Linux of compiler host is 32bit，you can skip this step。
安装aptitude包管理工具
install aptitude package management tool
$ sudo apt-get –y install aptitude
My-rk32-ek314build 2.2.1.3.jpg
使用aptitude安装ia32-libs
install ia32-libs with aptitude
$ sudo aptitude –y install ia32-libs
提示：下图为安装过aptitude和ia32-libs后，再次执行安装命令的截图。
tips：following is the screenshots with re-execution of installation command after installation of aptitude and ia32-libs is finished。
My-rk32-ek314build 2.2.1.4.jpg
3）安装mkimage工具
install mkimage tool
$ sudo apt-get -y install uboot-mkimage
提示：下图为安装过mkimage工具后，再次执行安装命令的截图。
tips：following is the screenshots with re-execution of installation command after installation of mkimage tool is finished。
My-rk32-ek314build 2.2.1.5.jpg
4）安装ncurses-dev
install ncurses-dev
说明：make menuconfig对其具有依赖性质。
instruction：make menuconfig is dependent on it。
$ sudo aptitude -y install ncurses-dev
提示：下图为安装过ncurses-dev工具后，再次执行安装命令的截图。
tips：following is the screenshots with re-execution of installation command after installation of ncurses-dev tool is finished。
My-rk32-ek314build 2.2.1.6.jpg
使配置文件生效(validate configured file)
执行source命令
execute source command
$ source ~/my-rk3288/03_tools/gcc-arm-eabi-4.6-env
My-rk32-ek314build 3.2.1.jpg
查看编译配置
view compiler configuration
$ echo $ARCH
$ echo $CROSS_COMPILE
提示：可看到ARCH和CROSS_COMPILE被设置
tips：you can see that ARCH和CROSS_COMPILE is configured
My-rk32-ek314build 3.2.2.jpg
验证交叉编译工具配置
verify cross compiler tool configuration
$${CROSS_COMPILE}gcc –v
提示：执行命令后可以看到终端显示出交叉编译工具的版本信息。如下图：
tips：you can see version information of cross compiler tool shown on terminal after execution of command.as below：
My-rk32-ek314build 3.2.3.jpg
清除u-boot配置(remove u-boot configuration)
$ make distclean
My-rk32-ek314build 3.3.1.jpg
编译(compilation)
执行编译
execute compilation
$ make
提示：这里为了提高编译速度，在make后面加了“-j4”。这里编译的Linux主机是双核4线程的，所以“-j”后面用了4，也就是采用4线程编译。“-j”后面的数字可以根据系统资源分配，但是不应该超过编译主机最大支持的线程数。
Tips：To speed up the compilation，add "-j4" after make.The Linux host used to compile is dual-core ,4 threads .So "-j" is followed by 4, which takes 4 threads to compile. The number behind "-j" is allocated based on system resources,but It should not exceed the maximum threads the host support。
My-rk32-ek314build 3.5.1.jpg
编译完成
complete compilation
提示：u-boot编译过程大概需要十几秒钟的时间。
tips：u-boot compilation process will take a few minustes or so。
