交叉编译 armhf 并安装静态库

我已经设置了一个交叉编译docker实例。简而言之，我开始设置

apt-get update
apt-get install binutils-multiarch

dpkg --add-architecture armhf
# Manually add correct armhf repositories to /etc/apt/sources.list
apt-get update
apt-get install libudev-dev:armhf

在最后一步中，我收到以下错误：

The following packages have unmet dependencies:
libudev-dev:armhf : Depends: libacl1:armhf (>= 2.2.51-8) but it is not going to be installed
                    Depends: libblkid1:armhf (>= 2.19.1) but it is not going to be installed
                    Depends: libc6:armhf (>= 2.17) but it is not going to be installed
                    Depends: libgcc1:armhf (>= 1:3.5) but it is not going to be installed
                    Depends: libkmod2:armhf (>= 5~) but it is not going to be installed
                    Depends: libselinux1:armhf (>= 2.0.65) but it is not going to be installed
                    Depends: libudev1:armhf (= 229-4ubuntu4) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

手动安装这些不是一个选项，因为libc6:armhf它们与当前安装的 amd64 libc6 冲突，最终会覆盖此包。我只想设置包libudev:armhf以便我可以链接到它。

/etc/apt/sources.list：

deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial main restricted
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ xenial main restricted

deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial-updates main restricted

deb [arch=amd64] http://security.ubuntu.com/ubuntu/ xenial-security universe
deb [arch=amd64] http://security.ubuntu.com/ubuntu/ xenial-security multiverse

运行apt-cache policy libudev-dev:{amd64,armhf}输出以下内容：

libudev-dev:

答案1

步骤 1-打开终端：

按Ctrl+ Alt+ T。

第 2 步 - 备份：

执行：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.old

步骤 3——打开编辑器：

执行：

sudo gedit /etc/apt/sources.list

如果您愿意，您可以使用其他编辑器。

步骤 4-编辑sources.list：

删除此处的所有内容并添加以下内容：

deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial main multiverse restricted universe
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ xenial main multiverse restricted universe
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ xenial-updates main multiverse restricted universe
deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial-updates main multiverse restricted universe
deb [arch=amd64] http://security.ubuntu.com/ubuntu/ xenial-security main multiverse restricted universe

保存并退出。

步骤 5 - 更新您的存储库索引：

执行：

sudo apt update

步骤 6 - 安装libudev-dev架构armhf：

执行：

sudo apt install libudev-dev:armhf

澄清：多架构软件包需要在所有架构上安装相同的版本。因此，您应该有libudev-dev:armhf版本229-4ubuntu21.4，但您当前的存储库配置不包括此版本。因此，您应该添加xenial-updates支持此版本的行。

关于其他建议添加的渠道，我建议您添加这些以防出现问题。

答案2

我尝试了这些步骤，但仍然面临同样的错误

答案3

对于 Ubuntu 22.04，我遵循了@Olimjon 的回答，但更改了以下内容：

步骤1：编辑文件

sudo gedit /etc/apt/sources.list

第2步：根据这里的答案如何使用 apt-get 下载多架构库？
在所有现有条目的“deb”后插入“[arch=amd64]”，这样它将保留其原始架构，
现在看起来应该像这样：

...
deb [arch=amd64] http://us.archive.ubuntu.com/ubuntu/ [???] main restricted universe multiverse
...

[???] 取决于您的 Ubuntu 版本。

步骤3：在底部添加，但将 [???] 替换为步骤 2 中的内容

deb [arch=armhf,arm64] http://ports.ubuntu.com/ [???] main restricted
deb [arch=armhf,arm64] http://ports.ubuntu.com/ [???]-updates main restricted
deb [arch=armhf,arm64] http://ports.ubuntu.com/ [???] universe
deb [arch=armhf,arm64] http://ports.ubuntu.com/ [???]-updates universe
deb [arch=armhf,arm64] http://ports.ubuntu.com/ [???] multiverse
deb [arch=armhf,arm64] http://ports.ubuntu.com/ [???]-updates multiverse
deb [arch=armhf,arm64] http://ports.ubuntu.com/ [???]-backports main restricted universe multiverse

我尝试了其他问题中的 [???]、xenial、focal、kinetic 等，但不知道它们是什么意思。
它应该是你正在使用的 Ubuntu 版本的“代号”。
在我的情况下，它是 22.04 LTS 的 jammy，所以我的代号是：

deb [arch=armhf,arm64] http://ports.ubuntu.com/ jammy main restricted
deb [arch=armhf,arm64] http://ports.ubuntu.com/ jammy-updates main restricted
deb [arch=armhf,arm64] http://ports.ubuntu.com/ jammy universe
deb [arch=armhf,arm64] http://ports.ubuntu.com/ jammy-updates universe
deb [arch=armhf,arm64] http://ports.ubuntu.com/ jammy multiverse
deb [arch=armhf,arm64] http://ports.ubuntu.com/ jammy-updates multiverse
deb [arch=armhf,arm64] http://ports.ubuntu.com/ jammy-backports main restricted universe multiverse

步骤4：在终端中运行

sudo apt update

步骤5：安装你需要的包

sudo apt install libudev-dev:armhf

笔记：这些步骤也解决了类似的问题：
https://unix.stackexchange.com/questions/329165/installing-libudev-for-arm-on-x64-ubuntu
https://unix.stackexchange.com/questions/608001/having-trouble-with-an-unmet-dependencies-loop-using-apt

笔记：我也有，基于此：https://unix.stackexchange.com/questions/728589/in-depth-explanation-of-components-in-sources-list

deb [arch=armhf,arm64] http://archive.ubuntu.com/ubuntu jammy main universe restricted multiverse
deb [arch=armhf,arm64] http://archive.ubuntu.com/ubuntu jammy-updates main universe restricted multiverse
deb [arch=armhf,arm64] http://archive.ubuntu.com/ubuntu jammy-backports main universe restricted multiverse

它可能不适用于交叉编译，但当一切开始工作时我就用过它。我删除了这些行并重新安装了一些软件包，它仍然有效。

笔记：添加架构

sudo dpkg --add-architecture arm64
sudo dpkg --add-architecture armhf # 32-bit arm
