手动指定内核版本编译

[wehyy]

您好，我想请教一下跨内核版本编译的场景，具体而言是在 kernel 4.15.0 中编译 kernel 4.9.0 的 nettrace 工具，目前在编译过程中遇到了以下问题：

~/workspace/nettrace/nettrace$ docker run -it --rm --network=host --privileged -v $(pwd):$(pwd) -v /lib/modules/:/lib/modules/ -v /usr/src/:/usr/src/ imagedong/nettrace-build make -C $(pwd) NO_BTF=1 NO_GLOBAL_DATA=1 KERNEL=/home/ubuntu/workspace/nettrace/nettrace/linux all

作为内核开发的新手，我是直接将 kernel 4.9.0 的源码路径作为 KERNEL 参数，但这明显是不对的，想请教一下如何获得低版本例如 kernel 4.9.0 的头文件，目前 apt-get install 列表已不再维护该内核版本的 linux-headers

而且当我获取了 linux-headers-4.9.0-8-amd64 内核头文件后，指定该路径仍会报错：
