# tinycore-kernel
2-
TinyCore Linux kernel and module compile scripts
2+
3+
Build a [TinyCore Linux](http://tinycorelinux.net/) kernel, modules, and firmware extensions
4+
5+
# Getting Started
6+
7+
Clone this repository.
8+
9+
### Building a kernel from scratch
10+
11+
The default kernel is `3.16.6-tinycore64`
12+
13+
1. `make kernel`
14+
2. `cd /tmp/tinycore-kernel-build`
15+
3. The kernel will be named `vmlinuz64`
16+
17+
### Building default module extensions
18+
19+
Default modules extensions are `all, base, filesystems, ipv6, mtd, netfilter, raid-dm, scsi`.
20+
21+
The `all` extension will contain _all_ the modules.
22+
23+
The `base` extension will contain the _base_ modules which are included of the OS `core.gz/corepure64.gz`.
24+
25+
1. `make extensions`
26+
2. `cd /tmp/tinycore-kernel-build`
27+
3. The module extensions will be named `<module>-3.16.6-tinycore64.tcz`
28+
29+
### Rebuilding the OS (remaster) with new modules
30+
31+
The default OS will be searched for in `/opt/tinycore/6.x/x86_64/release/distribution_files/`.
32+
33+
1. `make os`
34+
2. `cd /tmp/tinycore-kernel-build`
35+
3. The compressed OS will be named `corepure64.gz` and uncompressed OS will be named `corepure64`
36+
37+
### Cleaning up
38+
39+
Many directories and files will be created in the `WORKDIR`, to cleanup, simply type `make clean`.
40+
41+
# Makefile variables
42+
43+
The following variables can be changed at build time, by specifying them as arguments, ex: `make MODULES=ipv6`
44+
45+
* `MODULES`: List of modules to build
46+
* `KERNEL`: Kernel version to build
47+
* `KERNEL_ARCH`: Kernel architecture to build, either `x86_64` or `x86`
48+
* `KERNEL_SOURCE`: URL of the kernel source package (`.tar.xz or .txz`)
49+
* `KERNEL_SHA256`: SHA256 hash of the kernel source package
50+
* `OSDIR`: Local system directory containing the TinyCore OS (`core.gz or corepure64.gz`)
51+
* `WORKDIR`: Temporary work path to build all the files
52+
53+
# Notes
54+
55+
This is a very early initial release, so it may be buggy, and might not be complete. Please inspect `WORKDIR` after building, if you want to package firmwares or additional modules.
