[md]# 序言
- 最终编译的几个Qt示例应用视频演示：
https://www.bilibili.com/video/BV1NG411Q7QH
# 开发环境
- Windows 11
- DevEco Studio 3.1 Release
- OpenHarmony Full-SDK 3.2.12.5
- Qt For OpenHarmony SDK [Qt5.12.12_alpha_v3](
https://gitee.com/openharmony-si ... /Qt5.12.12_alpha_v3
)
# 环境搭建
- [OpenHarmony-SIG / qt](
https://gitee.com/openharmony-sig/qt
)
- [Qt For OpenHarmony SDK使用说明](
https://gitee.com/openharmony-si ... 8%E8%AF%B4%E6%98%8E
) `先参考仓库文档进行操作`
- 下载 Qt For OpenHarmony SDK
- Qt IDE 开发环境配置
- Qt Widget 示例编译及部署
开源仓库的Wiki中图文并茂，写的比较详细，不过还是有一些遗漏或者有点模糊的地方，下面是我在搭建开发环境是碰到的若干问题，并给出了相应的解决方式
## 环境变量配置问题
`OHOS_SDK_PATH` 一定要指向 OpenHarmony SDK 中 `native` 文件夹的上级目录
## 构建套件配置问题
如果你碰到提示：`Qt没有被正确安装，请运行make install`，如下图所示
则需要在 `qmake.exe` 同一文件夹下（`qt_oh_sdk_3.2.12.5_bin\Qt5.12.12\aarch64-windows-ohos\bin`），创建一个 `qt.conf` 文件（ANSI格式），内容为：
```ini
[paths]
Prefix = ..
```
然后删除刚才添加的qmake.exe，再重新添加一次即可
## 应用运行闪退问题
应用运行闪退，查看log定位问题
```log

找到 `src/main/ets/native/QtApplication.ts`
```js
import qpa from "libplugins_platforms_qopenharmony.so";
......
this.windowStage.on("windowStageEvent", (state) => {
qpa.updateApplicationState(state);
console.log("window stage changed", state);
});
```
错误原因是找不到 `libplugins_platforms_qopenharmony.so`
- 这个so的位置在 `qt_oh_sdk_3.2.12.5_bin\Qt5.12.12\aarch64-windows-ohos\plugins\platforms\libplugins_platforms_qopenharmony.so`
- 把 `libplugins_platforms_qopenharmony.so` 复制到项目的 `entry\libs\arm64-v8a` 目录下
