在 Mac 上运行docker

Linux 标准库

我的目标是淘汰用于构建一些好的旧 C 代码的专用笔记本电脑，并改用 docker 容器。

为了编译我的代码，我Makefile正在寻找运行

Makefile:       /usr/bin/make -C /lib/modules/$(shell uname -r)/build M=$(PWD)/linux/$* modules

不幸的是modules文件夹是空的

mysuer@d112db1e835e:~/robot$ ls -al /lib/modules/
ls: cannot access /lib/modules/: No such file or directory

在我的 linux 机器上，我可以找到模块

$ ls -al /lib/modules/
total 28
drwxr-xr-x  7 root root 4096 Dez 13  2016 .
drwxr-xr-x 24 root root 4096 Apr 24  2017 ..

drwxr-xr-x  5 root root 4096 Nov 24  2015 3.13.0-68-generic

但我的 docker 中没有模块。

在我的码头上

uname -r
4.9.60-linuxkit-aufs

因此

/usr/bin/make -C /lib/modules/4.9.60-linuxkit-aufs/build .... FAILS

/lib/modules/4.9.60-linuxkit-aufs不在这里。

我该如何解决这个问题？

尝试安装标头
