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-imx6 作为工作目录
create ~/my-imx6 as working directory

$ mkdir ~/my-imx6
Myimx6l3035 build 2.1.1.1.jpg

创建 ~/my-imx6/02_source/imx_3.0.35_4.1.0 作为源码目录
create ~/my-imx6/02_source/imx_3.0.35_4.1.0 as source code directory

$ mkdir ~/my-imx6/02_source/imx_3.0.35_4.1.0 -p
Myimx6l3035 build 2.1.1.2.jpg

创建 ~/my-imx6/03_tools 作为工具目录
create ~/my-imx6/03_tools as tool directory

$ mkdir ~/my-imx6/03_tools -p
Myimx6l3035 build 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-imx6/02_source/imx_3.0.35_4.1.0”,将网盘中“03_工具/toolchain”复制到Linux开发主机的“~/my-imx6/03_tools”。
tip:this step is to copy “02_source code”from network disk to “~/my-imx6/02_source/imx_3.0.35_4.1.0”in development host,and copy “03_tool/toolchain”to “~/my-imx6/03_tools”。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-imx6/02_source/imx_3.0.35_4.1.0
$ tar xf u-boot-2009.08--svn*.tar.xz
$ tar xf linux-3.0.35--svn*.tar.xz
Myimx6l3035 build 2.1.2.1.jpg

2)解压交叉编译工具
decompress cross compiler tool

$ cd ~/my-imx6/03_tools/
$ tar jxf gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12.tar.bz2
Myimx6l3035 build 2.1.2.2.jpg

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
Myimx6l3035 build 2.2.1.3.jpg

$ sudo apt-get –y install aptitude

Myimx6l3035 build 3.1.0.1.jpg


使配置文件生效(validate configured file)

  • 执行source命令

execute source command

$ source ~/my-imx6/03_tools/myimx6_3035_build_env
Myimx6l3035 build 3.2.0.1.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
Myimx6l3035 build 3.2.0.2.jpg

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:
Myimx6l3035 build 3.2.0.3.jpg


清除u-boot配置(remove u-boot configuration)

$ make distclean
Myimx6l3035 build 3.3.0.1.jpg

  • 评估板及对应的 u-boot 编译配置:

evaluation board and its corresponding u-boot compiler configuration:

评估板主型号

CPU类型-内存容量
(CPU type-memory capacity)
对应的u-boot配置

MYIMX6EK200-6Qxx-1G configuration example:

$ make myimx6ek200_6q_config
Myimx6l3035 build 3.3.0.2.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。
Myimx6l3035 build 3.5.0.1.jpg

  • 编译完成

complete compilation
提示:u-boot编译过程大概需要几分钟时间。
tips:u-boot compilation process will take a few minustes or so。
Myimx6l3035 build 3.5.0.2.jpg


目标文件(target file)

  1. include <stdio.h>

int main(int argc, char **argv)
{
   printf("Hello, MYZR!\n");
   
   return;
}

3) 查看代码
