我想交叉编译一个程序，该程序与 SAM_A5d27 板上的设备“/dev/i2c-0”进行通信。为此，我需要 Ubuntu-18.04 桌面中的 libi2c-dev 包。由于 SAM_A5d27 具有 arm 架构，因此我将 armhf 架构添加到“dpkg”，并尝试在 armhf 中安装 libi2c-dev，但出现错误“E：无法找到包 libi2c-dev：armhf”。我遵循了以下步骤。请看一下并帮助我解决这个问题。
gp@guru-hp:~$ sudo dpkg --add-architecture armhf

我已经在 ubunt 包管理器站点中验证了 libi2c-dev 包的可用性。https://packages.ubuntu.com/bionic/libi2c-dev
答案1
armhf 包不在 universe 存储库中。我在http://ports.ubuntu.com
以下是我获取 4.0-2 版本所做的事情：
$ wget http://ports.ubuntu.com/pool/universe/i/i2c-tools/libi2c-dev_4.0-2_armhf.deb
$ sudo dpkg --force architecture --install ./libi2c-dev_4.0-2_armhf.deb
这确实会引发一条错误消息：
dpkg: warning: overriding problem because --force enabled:
dpkg: warning: package architecture (armhf) does not match system (amd64)
(Reading database ... 52515 files and directories currently installed.)
Preparing to unpack ./libi2c-dev_4.0-2_armhf.deb ...
Unpacking libi2c-dev:armhf (4.0-2) over (4.0-2) ...
dpkg: dependency problems prevent configuration of libi2c-dev:armhf:
libi2c-dev:armhf depends on libi2c0 (= 4.0-2).
dpkg: error processing package libi2c-dev:armhf (--install):
dependency problems - leaving unconfigured
Errors were encountered while processing:
libi2c-dev:armhf
但它确实提供了所需的库，并将其放入文件系统中的合理位置，这样您的 amd64 主机就不会混乱。
安装完成后，我的引用-li2c的交叉编译项目链接正确。
