适合 Linux 用户空间程序的构建环境

Question

I need to build a Linux user-space program that includes headers from the Linux Kernel. However those headers in turn seem to use other headers and so on. So my question is, what is the proper/good way of including all off the possible directories I could require in my Makefile? Thank you.

Answer 1

Most user-space programs using the Linux kernel headers don't need to do anything special. linux/ is already included in the default include paths, eg #include <linux/netlink.h> . Distributions will include these files as part of their stanh>dard developer package, for example build-essential on Debian.

You can also get headers specific for your kernel version, which is required when building a kernel module, but userspace programs will typically only interact with sockets and pipes and thus just need some structure definitions or protocol helpers for those channels (for example, Netlink).
