### 编译环境依赖：
|
||||
1. meson
|
||||
mesa是使用meson进行编译的并要求版本>= 0.52，可执行以下命令安装meson
|
||||
```
|
||||
sudo apt-get install python3 python3-pip ninja-build
|
||||
pip3 install --user meson
|
||||
```
|
||||
2. pkg-config
|
||||
meson配置编译环境时会使用pkg-config查找依赖库和头文件，可以执行以下命令安装
|
||||
```
|
||||
sudo apt-get install pkg-config
|
||||
```
|
||||
|
||||
### 编译步骤如下：
|
||||
1. 下载openharmony整个工程代码，并完成编译
|
||||
2. 因为有些依赖库是静态库，整编后会被删除需要执行以下命令单独编译以rk3568为例
|
||||
```
|
||||
./build.sh --product-name=rk3568 --build-target=expat
|
||||
./build.sh --product-name=rk3568 --build-target=libwayland_server.0
|
||||
./build.sh --product-name=rk3568 --build-target=libwayland_client.0
|
||||
./build.sh --product-name=rk3568 --build-target=libwayland_server
|
||||
./build.sh --product-name=rk3568 --build-target=libwayland_client
|
||||
```
|
||||
|
||||
3. 编译mesa
|
||||
编译鸿蒙系统下的mesa库时，需要配置鸿蒙的交叉编译链和依赖的库，相关配置和编译步骤已经封装到ohos目录下的python脚本中，编译时只需执行 build_wayland_and_gbm.py 脚本即可，执行命名需要输入三个参数
|
||||
|
||||
| 参数 | 说明 |
|
||||
| ---- | ---- |
|
||||
| arg1 | openharmony代码路径 |
|
||||
| arg2 | 产品名字，实际上为out目录下存放系统编译结果的那个目录 如hi3516dv300 或则 rk3568， 注： LTS3.0 的版本必须是 ohos-arm-release|
|
||||
| arg3 | mesa 源码路径|
|
||||
|
||||
示例如下：
|
||||
~/openharmony 是openharmony源码路径， rk3568是对应的产品输出目录，~/mesa3d为mesa源码路径, 执行完命令后会生成一个名叫builddir的文件夹，该文件夹是mesa的编译目录. 编译完成后相关的库存放在builddir/install/lib 下
|
||||
|
||||
```
|
||||
cd ~/mesa3d
|
||||
python ohos/build_wayland_and_gbm.py ~/openharmony rk3568 ~/mesa3d
|
||||
|
||||
```
