MacOS Catalina 从源码构建Qt6.2开发库之01: 编译Qt6.2源代码
安装xcode， cmake， ninja
brew install node
mac下安装OpenGL库并使之对各项目可见
在macOS上安装OpenGL通常涉及到安装一些依赖库，如MGL、GLUT或者是GLEW等，同时确保LLVM的OpenGL框架和相关工具链的兼容性。以下是一个基本的安装步骤，你可以在终端中执行：
- 安装Homebrew（如果还没有安装的话）：
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
- 安装MGL（Mac上的OpenGL开发库）：
brew install mgl
- 安装GLUT（OpenGL Utility Toolkit）：
brew install freeglut
对于较旧的系统，你可能需要安装GLUT的较旧版本：
brew install freeglut --with-contrib
- 安装GLEW（OpenGL Extension Wrangler Library）：
brew install glew
- 配置你的项目：
每个步骤之后，确保你的工作目录下有相应的头文件和库文件路径。你可以通过在.pro文件（对于Qt项目）或适当的地方设置C_INCLUDE_PATH和LIBRARY_PATH环境变量来设置路径。 - 添加环境变量：
export CPPFLAGS="-I/usr/local/opt/glew/include" - export LDFLAGS="-L/usr/local/opt/glew/lib"
如果你需要重复使用这些环境变量，可以将它们添加到你的.bash_profile或.zshrc文件中。- 编译和链接你的程序：
在编译和链接你的OpenGL程序时，确保你的构建系统（如CMake、Makefile或IDE）能够找到这些库和头文件。
解压qt-everywhere-src-6.2.0.tar.xz到/Volumes/MacOS/Program/， 将目录名改为qt6.2.0
终端窗口进入/Volumes/MacOS/Program/qt6.2.0/，执行：
./configure
用CMake打开项目，设置安装目录为/usr/local
cmake —build . —parallel
修改下面的文件，明确链接OpenGL：

发现报错：

文件缺失：qt-6.2.0/qtwebengine/src/3rdparty/chromium/components/spellcheck/spellcheck_buildflags.h
手工创建该文件，写入内容
#define ENABLE_SPELLCHCEK 0
#define BUILDFLAG_INTERNAL_ENABLE_SPELLCHECK 0
修改文件browser_context.h第352行如下
//#if defined(TOOLKIT_QT) && BUILDFLAG(ENABLE_SPELLCHECK)
#if defined(TOOLKIT_QT)
// Inform about not working dictionary for given language
virtual void FailedToLoadDictionary(const std::string& language) = 0;
#endif
最后执行
cmake —build . —parallel
cmake --install .
