archbuild 使用参考

使用流程

  1. archbuild 的使用大多是由软链接链接过来执行的，比如

    $ ls /usr/bin/*-x86_64-build  -l
lrwxrwxrwx 1 root root 9 Jul 14 12:27 /usr/bin/extra-x86_64-build -> archbuild
lrwxrwxrwx 1 root root 9 Jul 14 12:27 /usr/bin/gnome-unstable-x86_64-build -> archbuild
lrwxrwxrwx 1 root root 9 Jul 14 12:27 /usr/bin/kde-unstable-x86_64-build -> archbuild
lrwxrwxrwx 1 root root 9 Jul 14 12:27 /usr/bin/staging-x86_64-build -> archbuild
lrwxrwxrwx 1 root root 9 Jul 14 12:27 /usr/bin/testing-x86_64-build -> archbuild

  2. 默认大家都安装了默认开发工具集 base-devel 的软件包，如果开发者未安装该工具集，则会在运行上一节中的 _-_-build 相关命令时报错，报错信息如下：

    ==> ERROR: Cannot find the strip binary required for object file stripping.
==> ERROR: Could not download sources.

    如果出现以上报错，需要安装 base-devel 工具集，命令如下：

    $ sudo pacman -S base-devel

  3. 在包含 PKGBUILD 文件的路径下运行extra-x86_64-build，首先会调用 root 权限，然后检查 base-devel 工具集，之后检查源码的 GPG 公钥

    devtools-20210202.tar.gz ... FAILED (unknown public key FC1B547C8D8172C8)

  4. 导入缺失的公钥

    $ gpg --recv-keys FC1B547C8D8172C8
gpg: /home/tsuibin/.gnupg/trustdb.gpg: trustdb created
gpg: key FC1B547C8D8172C8: public key "Levente Polyak (anthraxx) <[email protected]>" imported
gpg: Total number processed: 1
gpg:               imported: 1

  5. 完成后，再来重新运行 extra-x86_64-build

  6. 运行结果（此处以 devtools，降级过的 ruby-bundler 举例）

    • devtools

      ==> ERROR: The built package (devtools) is the one in the repo right now!

      说明该软件包已经打包完成，只不过，软件包于仓库中的版本一样

    • 降级后的 ruby-bundler

      说明该软件包打包完成。

跨平台打包

比如我们目前正在做的 riscv64 移植工作，需要在 x86_64 环境下编译 riscv64 的程序，我们可以这样做：

过时内容

  1. 首先创建软连接将文件 extra-riscv64-build 链接到 archbuild (/usr/bin/extra-riscv64-build -> archbuild )

    $ cd /usr/bin/

    $ sudo ln -s archbuild extra-riscv64-build

  1. 导入 Arch Linux CN 源，安装 devtools-riscv64

  2. 进入到你要打包的软件目录,目录下需要由 PKGBUILD 文件，执行如下命令

    # extra-riscv64-build -- -d "/tmp/cache:/var/cache/pacman/pkg"

    参数说明:

    • -- 将参数传递到 extra-riscv64-build 程序的下一层（实际上是给了 makechrootpkg 这个程序）
    • -d 以读写的方式绑定目录到打包 build chroot (将/tmp/cache 用来保存下载的软件包，使用前需要先创建这个目录，不然会报错)

Tips: 如果遇到如 /var/lib/archbuild/extra-riscv64/root does not appear to be an Arch chroot， 或者 invalid or corrupted package 的错误， 你可以给 archbuild 带上 -c 参数： extra-riscv64-build -c -- -d .....

  • -c 参数会检查当前是否有其他用户正在运行 archbuild，如果没有会清理掉 /var/lib/archbuild/extra-riscv64/ 目录下的 所有目录和 *.lock 文件。

待补充

当用户执行extra-x86_64-build，系统做了哪些工作。
