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：

1. 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)"
3. 安装 MGL （Mac上的OpenGL开发库）：
   brew install mgl
5. 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
7.
8. 安装 GLEW （OpenGL Extension Wrangler Library）：
brew install glew
9.
10. 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。
11. 添加环境变量 ：
export CPPFLAGS="-I/usr/local/opt/glew/include"
12. export LDFLAGS="-L/usr/local/opt/glew/lib"
13.

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。

14. 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/us r/local

cmake ---build . ---parallel

终端窗口进入/Volumes/MacOS/Program/qt6.2.0/，执行：

cmake ---build . ---parallel

发现报错：

In file included from ../../../3rdparty/chromium/content/public/browser/browser_accessibility_state.h:12:

../../../3rdparty/chromium/content/public/browser/browser_context.h:21:10: fatal error: 'components/spellcheck/spellcheck_buildflags.h' file not found

#include "components/spellcheck/spellcheck_buildflags.h"

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 .
