c++ - libcurl4-openssl-dev :armhf cannot be installed when libcurl4-openssl-dev is already installed

Question

我在 Debian Jessie 8.10 amd64 上创建了一个 c++ 应用程序，它还需要以下库:

sudo apt-get install libssl-dev
sudo apt-get install libcurl4-openssl-dev

我还需要交叉编译armhf的源代码。所以根据这个非常有用的链接 https://wiki.embeddedarm.com/wiki/Jessie_armhf_Cross_Compile我给出了以下命令:

sudo apt-get install curl build-essential
su root
echo "deb http://emdebian.org/tools/debian jessie main" > 
/etc/apt/sources.list.d/emdebian.list
curl http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | apt-key add -
dpkg --add-architecture armhf
apt-get update
apt-get install crossbuild-essential-armhf

一切都已正确安装，然后我还给出了:

 sudo apt-get install libssl-dev:armhf
 sudo apt-get install libcurl4-openssl-dev:armhf

第一个命令执行成功。另一方面，第二个未能给出以下输出:

由于我在交叉编译过程中还很陌生，有人知道我做错了什么吗？

Answer 1

你没有做错任何事。这是与多体系结构包相关的文件冲突。这是一个 bug in the package

这是对此类错误的解释，来自 https://wiki.debian.org/MultiArch/Hints

The package in question is marked Multi-Arch: same, but has conflicting versions of at least one file for different architectures. The hint tells the filename (or the number of filenames) and the architectures (or number of architectures) in question. The easiest way to fix is to remove the Multi-Arch: same declaration, but often enough it can be fixed by moving the offending files to per-architecture locations (typically /usr/lib/$(DEB_HOST_MULTIARCH)/). For *-dev packages, the Multi-Arch: same capability often is not critical and removing is a good initial measure.

我只是遇到了同样的问题，这仍然是一些软件包的问题。在我的例子中，libcurl-openssl-dev 替换了 /usr/bin/curl-config 二进制文件。

对我来说，当我需要交叉编译时需要从 x64/i386 库进行交换，但我很清楚这可能不是对每个人都可行。
