在Windows下编译QScintilla

1. 配置QT环境变量,

下载链接 Riverbank Computing

本人编译时使用的是QScintilla_src-2.14.1 和 Qt 6.10.1

将qmake.exe和mingw32-make.exe两个程序所在的目录添加到windows环境变量中；

2. qmake qscintilla.pro 生成Makefile文件

QScintilla_src-2.14.1\src 目录中

qmake qscintilla.pro

3. mingw32-make 编译

QScintilla_src-2.14.1\src 目录中

mingw32-make

4. mingw32-make install 安装

QScintilla_src-2.14.1\src 目录中

mingw32-make install

5. 用演示程序验证 QScintilla 是否能运行
