<div class='showpostmsg'># RV1106 交叉编译

为了方便交叉编译，Buildroot提供了一个脚本。

## 配置

首先打开Buildroot的SDK配置脚本，有了这个脚本，我们可以基于Buildroot的环境编译应用程序。

进入Buildroot目录：`luckfox-pico/sysdrv/source/buildroot/buildroot-2023.02.6`

```bash
cd sysdrv/source/buildroot/buildroot-2023.02.6
make menuconfig
```

选择：`Host utilities -> host environment-setup`，保存编译

<ignore_js_op>

<div class="tip tip_4 aimg_tip" id="aimg_883332_menu" style="position: absolute; display: none" disautofocus="true">
<div class="xs0">
<p><strong>image-20250122143157354.png</strong> <em class="xg1">(51.63 KB, 下载次数: 0)</em></p>
<p>
<a href="javascript:;" class="loginf" >下载附件</a>

<a href="javascript:;" onclick="showWindow(this.id, this.getAttribute('url'), 'get', 0);" id="savephoto_883332" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=883332&handlekey=savephoto_883332">保存到相册</a>

</p>

</div>
<div class="tip_horn"></div>
</div>

</ignore_js_op>

进入目录`output/host`查看，发现`environment-setup`已经成功生成。测试一下

```bash
$ source environment-setup

$ echo $CC
arm-rockchip830-linux-uclibcgnueabihf-gcc
```

<ignore_js_op>

<div class="tip tip_4 aimg_tip" id="aimg_883333_menu" style="position: absolute; display: none" disautofocus="true">
<div class="xs0">

<a href="javascript:;" onclick="showWindow(this.id, this.getAttribute('url'), 'get', 0);" id="savephoto_883333" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=883333&handlekey=savephoto_883333">保存到相册</a>

</p>

</div>
<div class="tip_horn"></div>
</div>

</ignore_js_op>

交叉编译

```bash
➜test cat hello.c
#include <stdio.h>
int main() {
  printf("hello world!\n");
  return 0;
}

➜test $CC hello.c
➜test ls
a.outhello.c

# 查看文件类型
➜test file a.out
a.out: ELF 32-bit LSB pie executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-uClibc.so.0, not stripped
```

## 测试验证

将a.out上传到开发板，运行成功
