1，选择使用 wxWidgets 框架

选择这个主要是因为完全的开源，不想折腾 Qt的库，而且打包的文件比较大。

网络上面有很多的对比，而且使用QT的人比较多。
但是我觉得wxwidgets 更加偏向 c++ 语法本身，也有助学习C++。
没有太多的特殊封装，而且商业化更加友好，打包软件也比较少。

更偏向原生的系统，做好相关的功能开发。

2，在 ubuntu上进行安装320版本环境

https://www.wxwidgets.org/downloads/

https://docs.codelite.org/wxWidgets/repo320/

先增加证书授权：

# 增加签名
sudo apt-key adv --fetch-keys https://repos.codelite.org/CodeLite.asc#2 安装源
# 生成一个文件 /etc/apt/sources.list.d/archive_uri-https_repos_codelite_org_wx3_2_ubuntu_-jammy.list
# 不需要可以删除掉
sudo apt-add-repository 'deb https://repos.codelite.org/wx3.2/ubuntu/ jammy universe'#3，安装库
apt-get install libwxbase3.2-0-unofficial \libwxbase3.2unofficial-dev \libwxgtk3.2-0-unofficial \libwxgtk3.2unofficial-dev \wx3.2-headers \wx-common \libwxgtk-media3.2-0-unofficial \libwxgtk-media3.2unofficial-dev \libwxgtk-webview3.2-0-unofficial # 特别奇怪，其余的库要一个一个进行安装，不能批量执行。
sudo apt-get install libwxgtk-webview3.2unofficial-dev 
sudo apt-get install libwxgtk-webview3.2-0-unofficial-dbg 
sudo apt-get install libwxbase3.2-0-unofficial-dbg

3，解决编译问题 undefined reference to `pcre2_config_32’|

||=== Build: Debug in demo02 (compiler: GNU GCC Compiler) ===|

||=== Build failed: 9 error(s), 1 warning(s) (0 minute(s), 0 second(s)) ===|

终于找到问题，通过安装 libpcre2-dev 解决

sudo apt install libpcre2-dev

4，第一个hello world，并进行编译

参考在线手册：
https://docs.wxwidgets.org/3.2/
第一个hello world 文档：
https://docs.wxwidgets.org/3.2/overview_helloworld.html

// wxWidgets "Hello World" Program// For compilers that support precompilation, includes "wx/wx.h".
#include <wx/wxprec.h>#ifndef WX_PRECOMP#include <wx/wx.h>
#endifclass MyApp : public wxApp
{
public:virtual bool OnInit();
};class MyFrame : public wxFrame
{
public:MyFrame();private:void OnHello(wxCommandEvent& event);void OnExit(wxCommandEvent& event);void OnAbout(wxCommandEvent& event);
};enum
{ID_Hello = 1
};wxIMPLEMENT_APP(MyApp);bool MyApp::OnInit()
{MyFrame *frame = new MyFrame();frame->Show(true);return true;
}MyFrame::MyFrame(): wxFrame(NULL, wxID_ANY, "Hello World")
{wxMenu *menuFile = new wxMenu;menuFile->Append(ID_Hello, "&Hello...\tCtrl-H","Help string shown in status bar for this menu item");menuFile->AppendSeparator();menuFile->Append(wxID_EXIT);wxMenu *menuHelp = new wxMenu;menuHelp->Append(wxID_ABOUT);wxMenuBar *menuBar = new wxMenuBar;menuBar->Append(menuFile, "&File");menuBar->Append(menuHelp, "&Help");SetMenuBar( menuBar );CreateStatusBar();SetStatusText("Welcome to wxWidgets!");Bind(wxEVT_MENU, &MyFrame::OnHello, this, ID_Hello);Bind(wxEVT_MENU, &MyFrame::OnAbout, this, wxID_ABOUT);Bind(wxEVT_MENU, &MyFrame::OnExit, this, wxID_EXIT);
}void MyFrame::OnExit(wxCommandEvent& event)
{Close(true);
}void MyFrame::OnAbout(wxCommandEvent& event)
{wxMessageBox("This is a wxWidgets Hello World example","About Hello World", wxOK | wxICON_INFORMATION);
}void MyFrame::OnHello(wxCommandEvent& event)
{wxLogMessage("Hello world from wxWidgets!");
}

进行编译：

c++ -o main main.cpp  `wx-config --cxxflags --libs`

然后运行main

5，使用工具 codeblocks 进行开发

https://www.codeblocks.org/

https://www.codeblocks.org/downloads/binaries/

直接通过下载文件安装，或者apt 安装即可。

sudo apt install -y codeblocks

命令就是 codeblocks

可以按照模板，创建一个 wxWidgets的项目。

运行效果：

6，总结

已经有人总结了项目

继续学习 wxWidgets。
还有静态编译的办法，需要重新编译wxwidgets，否则没有库文件：
