macos下编译glfw

环境准备

# macos 环境配置，需要预装xcode和cmake
brew install cmake

# 下载源码
git clone https://github.com/glfw/glfw.git

编译

编译方式1：使用xcode编译

# cmake初始配置，生成编译文件
cd glfw
cmake -S . -B build_xcode -G Xcode

在build_xcode目录中找到GLFW.xcodeproj工程，打开运行即可，编译生成的可执行文件位于build_xcode/examples/Debug/splitview

编译方式2：命令行下编译

# cmake初始配置，生成编译文件
cd glfw
cmake -S . -B build

# 编译
cd build
make

编译生成的可执行文件位于build_xcode/examples目录下，这次不只是一个splitview

编译过程中遇到的问题

• No CMAKE_C_COMPILER could be found.

解决：需要确保xcode已安装，然后执行下面指令

sudo xcode-select --switch /Applications/Xcode.app/

1. xcode可以前往App Store安装

2. 执行完后需要删除build目录，重新执行初始配置命令生成编译工程

错误日志：
