# Yocto 基本使用和常见问题
|
||
|
||
## 交叉编译配置
|
||
|
||
在 yocto 根目录下：
|
||
|
||
```bash
|
||
source <sdk root>/oe-init-build-env
|
||
```
|
||
|
||
## 编译目标
|
||
|
||
使用如下命令查看所有编译目标：
|
||
|
||
```bash
|
||
bitbake -s
|
||
```
|
||
|
||
## 在 build 目录下进行编译
|
||
|
||
```bash
|
||
bitbake <target> -C compile
|
||
```
|
||
|
||
参数：
|
||
|
||
-C 强制编译，配置、编译目标并打包；
|
||
-c 不强制。
|
||
|
||
生成的文件在：
|
||
|
||
```bash
|
||
<yocto root>/build/tmp/deploy/images/<product>
|
||
```
|
||
|
||
目录下。
|
||
|
||
## Clean
|
||
|
||
注意：Clena 动作会清除 build/tmp 文件夹下的源码。
|
||
|
||
```bash
|
||
bitbake <target> -c cleansstate
|
||
```
|
||
|
||
## Linux Kernel
|
||
|
||
Kernel 源码在：
|
||
|
||
```bash
|
||
<yocto root>/build/tmp/work-shared/<product>/kernel-source
|
||
```
|
||
|
||
目录下。
|
||
|
||
Kernel 配置方法为：
|
||
|
||
```bash
|
||
bitbake linux-renesas -c do_menuconfig
|
||
```
|
||
|
||
## 常见问题
|
||
|
||
### Please use a locale setting which supports utf-8
|
||
|
||
Yocto 需要 locales 支持且设置为 UTF8。
|
||
|
||
```bash
|
||
# Ubuntu
|
||
sudo apt-get install locales
|
||
sudo dpkg-reconfigure locales
|
||
sudo locale-gen "en_US.UTF-8"
|
||
sudo update-locale LC_ALL="en_US.UTF-8" LANG="en_US.UTF-8"
|
||
export LANG="en_US.UTF-8"
|
||
```
