wxWidgets使用

源码编译安装

前往wxWidgets官网,下载wxWidgets

upload successful

打开Developer Command Prompt for VS 2022工具,进入 build\msw 目录,编译

1
nmake /f makefile.vc BUILD=debug SHARED=0 TARGET_CPU=X64

这里我编译了64位debug版的静态库,这里x64debug两个关键字很重要,你在VS中开发时,也要选择相应的配置
tip

属性管理器窗口添加wxWidgets目录下的wxwidgets.props文件
tip
这里我们还需要额外注意一下,因为我们跑的是GUI程序,所以需要在项目的属性中,把项目设置成窗口
upload
跑个简单的程序,hello.cpp
