Dependencies 已安装的库是；“失踪”；使用buildroot工具链进行交叉编译时

我有一个运行debian的虚拟机（x86_64体系结构），我正在为armv7平台设置一个交叉编译环境。我使用buildroot为armv7构建工具链，该部分工作正常：

makemenuconfig

，

makeSDK

，使用arm编译器复制并提取生成的tarball

但是，环境似乎缺少一些依赖项

例如，当尝试为dbclient（dropbear的客户端部分）配置$configure_标志时，我得到以下错误：

checking for deflate in -lz... no
configure: error: *** zlib missing - install first or check config.log ***

我在大多数情况下都使用buildroot，因此生成了这个文件，我

一切看起来都很好，而且正如预期的那样找到了正确的编译器。如您所见，我有buildroot的工具链，位于

dev系统确实包含zlib，当我尝试

安装zlib1g dev

时，我会收到以下消息：

zlib1g-dev is already the newest version (1:1.2.11.dfsg-0ubuntu2).

值得注意的是，我有一个具有相同问题的不同项目，但是对于libjson/json-c，也安装了libjson/json-c。因此，我相信这些问题是相关的，我的交叉编译环境遗漏了一些东西。我需要为arm平台获取这些库吗？或者，我是否以某种方式将我已经在系统中使用的工具包括在内？

我不太清楚为什么要运行虚拟机来执行交叉编译？你不能创建一个Arm虚拟机并用“本机”工具链编译它吗？@AndreiTumbar，因为virtualbox不是模拟器，因此不模拟CPU体系结构，而是依赖于主机系统的实际CPU体系结构。如果我可以完整地模拟ARM机器，我会的。也许可以尝试使用QEMU编译一个chroot环境（这将模拟ARM指令集）。我想看看Gentoo文档中的交叉编译：我不太清楚为什么要运行虚拟机来进行交叉编译？你不能创建一个Arm虚拟机并用“本机”工具链编译它吗？@AndreiTumbar，因为virtualbox不是模拟器，因此不模拟CPU体系结构，而是依赖于主机系统的实际CPU体系结构。如果我可以完整地模拟ARM机器，我会的。也许可以尝试使用QEMU编译一个chroot环境（这将模拟ARM指令集）。我将查看Gentoo文档以进行交叉编译：
