qscrcpy

文章目录

目的：

利用tcp/ip把手机投影到电脑上，不需要数据线连接，利用同一个局限网，实现无线连接。
我找了很多资料，还是选择QtScrcpy。
其中原因有三：

  • 第一，学习值得学的内容；
  • 第二，如何编译使用，遇到困难如何解决；
  • 第三，作为笔记。

QtScrcpy可以通过USB(或通过TCP/IP)连接Android设备，并进行显示和控制。不需要root权限。
同时支持GNU/Linux，Windows和MacOS三大主流桌面平台。

具体内容，就不再描述了，传送门：中文 英文

接下来，如何下载、如何编译、如何使用。

准备

准备什么，首先阅读作者的README.md,其中有说明安装过程，传送

Build
All the dependencies are provided and it is easy to compile.
PC client
1. Set up the Qt development environment on the target platform. Qt version>=5.12 (use MSVC 2019 on Windows)
2. Clone the project
3. Open the project root directory all.pro or CMakeLists.txt with QtCreator
4. Compile and run

上面描述，我们需要下载一些必备的依赖软件。

  • cmake >=3.19
  • Qt >= 5.12
  • MSVC 2019 及其以上 或者 MingW (我版本是:4.3.5)
  • Visual Studio 或者 make

缺了一个，那就不行了。至于如何安装，就不讲了。

下载

下载方式很多，能下载就OK。
我选择git克隆方法，于是打开poewrshell这个命令行。
如下代码：

按照我步骤去做，总算没错吧。

cd d:\
mkdir tools
cd tools
git clone https://github.com/barry-ran/QtScrcpy.git
cd QtScrcpy\QtScrcpy
mkdir build 
cd build

目前位置：d:\tools\QtScrcpy\QtScrcpy\build
命令输出结果：

提示：下载过程中数据不时出现断开网络或者没反应的情况，换个方式下载吧。

编译

编译时首先检查QT_DIR环境变量是否存在，若没有则设置
在这里插入图片描述
如下代码:

 cmake -G "MinGW Makefiles" ..
 # 选择MingW编译器，利用cmake编译一下.

  • 1
  • 2

结果输出如下:

PS D:\tools\QtScrcpy\QtScrcpy\build> cmake -G "MinGW Makefiles" ..

这时候在D:\tools\QtScrcpy\QtScrcpy\build上出现几个文件，其中Makefile文件，则表示可以用make命令,如下代码:

make

make命令后会发现有些问题，错误结果是：

意味着成功了，定位到 D:\tools\QtScrcpy\output\x64\RelWithDebInfo这个文件夹，并打开这个程序，是否运行成功。
如下截图：

在这里插入图片描述

上面如何下载，编译，使用，我就讲完了。 不管遇到问题，学会思考，为什么会出现错误，尝试能不能独立解决这个问题，并总结一下，若时间允许的话，可以记笔记。

原因分析：

错误1

D:\tools\QtScrcpy\QtScrcpy\res\QtScrcpy.rc:1:10: fatal error: winres.h: No such file or directory
 #include "winres.h"
          ^~~~~~~~~~

这个错误告诉我winres.h没有这个库，只要找到winres.h源代码，然后导入库，就行了。

错误2

PS D:\tools\QtScrcpy\QtScrcpy\build> make

这个是语法错误，要么注释，要么修改winres.h源代码。

解决方案：

解决错误1

D:\tools\QtScrcpy\QtScrcpy\res\QtScrcpy.rc:1:10到这行就错了，说明附近没有winres.h,那么我们只要在D:\tools\QtScrcpy\QtScrcpy\res上新建winres.h就行了，如下代码:

打开QtScrcpy.rc这个文件，然后注释一下。
