Mac搭建OpenHarmonyOS(开源鸿蒙系统)编译环境

从编译脚本上看是支持的mac的

case $(uname -s) in
    Darwin)
        HOST_DIR="darwin-x86"
        HOST_OS="mac"
        ;;
    Linux)
        HOST_DIR="linux-x86"
        HOST_OS="linux"
        ;;
    *)
        echo "Unsupported host platform: $(uname -s)"
        RET=1
        exit $RET
esac

• mac平台的只能在mac上编译(目前是)
• Linux上可以交叉编译出win
  • 编译命令默认也是会编译出Linux和win两个平台的sdk

mac上有一些要求，比如必须安装xcode。
默认最小版本 10.12，但是高于11不行。

_sdk_min_from_env = getenv("FORCE_MAC_SDK_MIN")
declare_args() {
  # Minimum supported version of the Mac SDK.
  if (_sdk_min_from_env == "") {
    mac_sdk_min = "10.12"
  } else {
    mac_sdk_min = _sdk_min_from_env
  }
}

-下面脚本只匹配的 10和11(目前是这样的，当前时间：20220528)

sdk_dir = os.path.join(
        str(out.rstrip(), encoding="utf-8"),
        'Platforms/MacOSX.platform/Developer/SDKs')
    # Xcode must be installed, its license agreement must be accepted, and its
    # command-line tools must be installed. Stand-alone installations (in
    # /Library/Developer/CommandLineTools) are not supported.
    # https://bugs.chromium.org/p/chromium/issues/detail?id=729990#c1
    file_path = os.path.relpath("/path/to/Xcode.app")
    if not os.path.isdir(sdk_dir) or not '.app/Contents/Developer' in sdk_dir:
        raise SdkError('Install Xcode, launch it, accept the license ' +
                       'agreement, and run `sudo xcode-select -s %s` ' % file_path +
                       'to continue.')
    sdks = [re.findall('^MacOSX(1[0,1]\.\d+)\.sdk$', s) for s in
            os.listdir(sdk_dir)]
    sdks = [s[0] for s in sdks if s]  # [['10.5'], ['10.6']] => ['10.5', '10.6']
    sdks = [s for s in sdks  # ['10.5', '10.6'] => ['10.6']
            if list(parse_version(s)) >= list(parse_version(min_sdk_version))]

Brew

如果没有brew,百度安装

如果有提示，请按照提示操作

重置brew.git

cd "$(brew --repo)"
git remote set-url origin https://github.com/Homebrew/brew.git

重置核心软件仓库

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://github.com/Homebrew/homebrew-core.git

重置Homebrew cask软件仓库

cd "$(brew --repo)"/Library/Taps/homebrew/homebrew-cask
git remote set-url origin https://github.com/Homebrew/homebrew-cask

python

• Version:3+

https://www.python.org/

brew install python3

git

gitee账号信息

• 生成公私钥

ssh-keygen -t rsa -C "message"

• 注册gitee

• 将本机ssh公钥放置gitee上

install git

• mac

brew install git

configure git

git config --global user.name "binny"
git config --global user.email "694285349@qq.com"
git config --global credential.helper store

install git-lfs

https://gitee.com/mirrors/git-lfs?_from=gitee_search

install repo

mkdir -p ~/.bin
PATH="${HOME}/bin:${PATH}"
curl https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > ~/.bin/repo
chmod a+rx ~/.bin/repo
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple requests

download master

Download

repo init -u git@gitee.com:openharmony/manifest.git -b master --no-repo-verify

Sync

repo sync -c -d -j8 --force-sync --fail-fast -q --no-tags --prune ; repo forall -j8 -c "git lfs pull"

• 或者

repo sync -c

• 同步大文件，好像是编译器之类的，没仔细看日志

repo forall -c 'git lfs pull'

这一步有输出警告，应该不影响，输出警告的文件：

vim /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/multiprocessing/resource_tracker.py

finally:
        # all processes have terminated; cleanup any remaining resources
        for rtype, rtype_cache in cache.items():
            if rtype_cache:
                try:
                    warnings.warn('resource_tracker: There appear to be %d '
                                  'leaked %s objects to clean up at shutdown' %
                                  (len(rtype_cache), rtype))
                except Exception:
                    pass
            for name in rtype_cache:
                # For some reason the process which created and registered this
                # resource has failed to unregister it. Presumably it has
                # died.  We therefore unlink it.
                try:
                    try:
                        _CLEANUP_FUNCS[rtype](name)
                    except Exception as e:
                        warnings.warn('resource_tracker: %r: %s' % (name, e))
                finally:
                    pass

brew 安装工具包

我开始在 mac 上大环境的时候，也是对着 Linux 上的名字安装了一部分。缺少去网上搜吧，下图是我本机的，仅供参考(下面的不都是 ohos 需要的)

ohos % brew list
==> Formulae
brotli      coreutils   git     icu4c       libunistring    mpdecimal   openssl@1.1 readline    wget
c-ares      gdbm        git-lfs     libidn2     libuv       node@12     pcre2       sqlite      xz
ca-certificates gettext     gmp     libnghttp2  macos-term-size openjdk@17  python@3.9  tree

brew update

brew install wget

• md5sum等

brew install coreutils

java环境

• 没有的话，自己安装，这个我以前装过，装 Java 环境，好装，百度吧

brew install openjdk@17

sudo ln -sfn /usr/local/opt/openjdk@17/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

echo 'export PATH="/usr/local/opt/openjdk/bin:$PATH"' >> ~/.zshrc 
source ~/.zshrc

java -version

prebuilts

• 执行prebuilts,在源码根目录下执行，安装编译器及二进制工具(注意文件名和路径，同事给我的名字有的都不一样了)

sudo bash build/prebuilts_download.sh –no-check-certificatie-skip-ssl

• 缺少啥就装啥。

sudo npm i -g nan

版本编译

• 编译 SDK

sudo ./build.sh --product-name ohos-sdk

• 单独安装的不支持

# Xcode must be installed, its license agreement must be accepted, and its
# command-line tools must be installed. Stand-alone installations (in
# /Library/Developer/CommandLineTools) are not supported.
# https://bugs.chromium.org/p/chromium/issues/detail?id=729990#c1
