MacPorts安装旧版本qemu

我在旧版本 macOS Big Sur 11.7.10 上执行 MacPorts 安装 QEMU

使用 ports 安装 qemu
ports install qemu

遇到安装错误:

具体的编译日志错误如下:

发现这里安装的是 qemu-10.1.1_0 ，根据之前 Homebrew安装旧版本qemu ，需要回退到 qemu-9.0.2

安装尚未安装的旧版本

MacPorts 使用 git 来管理仓库文件，要安装旧版本，需要先使用 git 回滚旧版本配置，然后进行安装。具体如下:

  • 找到正确的port commit:

首先访问 MacPorts仓库 ，点击 History 按钮找到旧版本

检索出旧版本qemu配置
# 获取仓库代码
git clone git@github.com:macports/macports-ports.git

# git log 检查提交日志，找到qemu相关项，定位到commit 589c443cbbd87d9b23cb4504f3e9d96556b4ff7e
# 参考 https://stackoverflow.com/questions/7124914/how-to-search-a-git-repository-by-commit-message
git log --all -i --grep="qemu: update to 9.0.2"

# 回滚到指定commit(搜索版本号
git checkout 589c443cbbd87d9b23cb4504f3e9d96556b4ff7e

  • 编译下载port:

编译下载port
cd emulators/qemu
sudo port install

这里有一个报错:

编译下载port报错
Error: Failed to open statefile for qemu: Could not open file: /Users/admin/Downloads/macports-ports/emulators/qemu/Portfile
Error: Follow https://guide.macports.org/#project.tickets if you believe there
is a bug.
Error: Processing of port qemu failed

奇怪，明明有这个 Portfile 文件，为何无法读取?

参考 Specify which version to install with macports ，我发现以前在svn时代，这个port代码仓库是放到 /tmp 目录下来完成 sudo port install

果然，我将 git 的这个仓库目录 macports-ports 移动到 /tmp 目录下(属主我改成了root，但可能不需要改)，就能够正常工作了

此时能够正常编译完成，并安装到 /usr/local/bin :

安装后的 qemu 执行文件
qemu-edid		qemu-nbd		      qemu-system-arm
qemu-img		qemu-storage-daemon	  qemu-system-i386
qemu-io			qemu-system-aarch64	  qemu-system-x86_64
