## 编译64位rockchip MPP库

1.下载mpp 1.8版本
```
git clone -b 1.0.8 https://git
ee.com/OpenHarmony_rk_equipment_transplantation/rk_mpp.git
```

2.修改rk_mpp/build/linux/aarch64/make-Makefiles.bash文件

```

# -DCMAKE_TOOLCHAIN_FILE=./arm.linux.cross.cmake \
# 修改为 OpenHarmony ndk本地的交叉编译配置文件
-DCMAKE_TOOLCHAIN_FILE=/root/OpenHarmony/temp1/linux/native/build/cmake/ohos.toolchain.cmake \

# 增加安装目录
-DCMAKE_INSTALL_PREFIX=/root/OpenHarmony/temp1/temp/mpp_output \
```

3.然后生成makefile,编译安装
```
./make-Makefiles.bash 
make -j 4
make install
```

## 编译32位rockchip MPP库

1.修改rk_mpp/build/linux/arm/make-Makefiles.bash

2.修改一下/root/OpenHarmony/temp1/linux/native/build/cmake/ohos.toolchain.cmake脚本，把他修改默认编译32位
