在开始前,由于 osx 默认的 apfs 文件系统不区分大小小写,所以首先得新建一块大小写敏感的 volume。
打开磁盘工具,进行分区
点击 +
号添加分区
在弹出的选择中点击 添加分区
设置分区名称、格式、大小。注意这里需要选择区分大小写的格式,这里使用了区分大小写的 APFS,分区大小至少为 15GB。
设置完成后点击 应用
开始分区。
等待分区完成
分区完成后,可以在 /Volumes/haiku/
访问此分区,接下来所有的工作都在这里进行。
基本上你可以参考 https://www.haiku-os.org/guides/building/get-source-git 获取源代码,这里我简要描述一下步骤。
首先你的电脑上应该已经安装了 git,并确保这两个值已经正确设置 user.name
与 user.email
,如果没有,可以这样设置
git config --global user.name "yourname"
git config --global user.email "youremail"
此外还需要设置 core.precomposeunicode
为 true
git config core.precomposeunicode true
haiku 没有直接使用 github 进行托管,你需要使用你的 github 在 https://review.haiku-os.org/ 登陆,记住你的用户名,在后面的步骤中要用到它。
代码分为两部分:buildtools 和 haiku,前者是 haiku 定制化的编译工具,包括 gcc 与构建工具 jam;后者则是 haiku 的源代码,
# 获取 buildtools
git clone "ssh://@git.haiku-os.org/buildtools" && scp -p <login>@git.haiku-os.org:hooks/commit-msg "buildtools/.git/hooks/"
# 获取 haiku
git clone "ssh://@git.haiku-os.org/haiku"
# 安装 commit 工具
scp -p <login>@git.haiku-os.org:hooks/commit-msg "haiku/.git/hooks/"
将其中的 MRNIU
,那么命令应该这样写
# 获取 buildtools
git clone "ssh://[email protected]/buildtools" && scp -p [email protected]:hooks/commit-msg "buildtools/.git/hooks/"
# 获取 haiku
git clone "ssh://[email protected]/haiku"
# 安装 commit 工具
scp -p [email protected]:hooks/commit-msg "haiku/.git/hooks/"
在编译之前,还需要做一些小小的改动
PS:在撰写本文时使用的是 hrev56168,如果使用最新代码,一些问题可能已经被修复。
gcc/gcc/config/host-darwin.c
最后一行添加宏
#if defined(__aarch64__)
const struct host_hooks host_hooks = HOST_HOOKS_INITIALIZER;
#endif
src/system/kernel/device_manager/device_manager.cpp
添加 #L1732 _AddPath(*stack, “busses/virtio”);
将 virtio 总线添加到搜索路径中
做好以上准备,就可以开始进行编译了。
安装依赖
brew install autoconf zstd xorriso gawk wget nasm less mpfr gmp libmpc bison libffi
安装构建工具 jam
cd /Volumes/haiku/buildtools/jam
make
sudo ./jam0 install
首先需要编译工具链
cd haiku
mkdir generated.arm
cd generated.arm
../configure -j8 --cross-tools-source ../../buildtools --build-cross-tools arm
编译完成后执行 jam -v
可以看到如下输出
> jam -v
Jam 2.5-haiku-20211029. OS=MACOSX. Copyright 1993-2002 Christopher Seiwald.
接下来编译可以在 qemu 上运行的 haiku 镜像
jam -j8 -q @minimum-mmc
编译完成后就可以准备运行了,我们使用 uboot 进行引导,在这里可以找到 u-boot.bin,将其复制到 generated.arm
目录下即可。
我们使用 qemu 进行模拟,但要注意我们要用的是 version 6.0.0。
使用 brew 安装 6.0.0 版本 qemu:
curl https://raw.githubusercontent.com/Homebrew/homebrew-core/b1268a3ecd418df8f7360c46ce3ee62a0599a1be/Formula/qemu.rb > /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/qemu.rb
brew install qemu
万事俱备,运行!
