Paul Spooren 9ae3c6f94c rules: add AUTORELEASE and COMMITCOUNT variables 
The lack of bumped PKG_RELEASE variables is a recurring theme on the
mailing list and in GitHub comments. This costs precious review time,
a rare good within the OpenWrt project.

Instead of relying on a manually set PKG_RELEASE this commit adds a
`commitcount` function that uses the number of Git commits to determine
the release. The function is called via the variables `$(AUTORELEASE)`
or `$(COMMITCOUNT)`. The `PKG_RELEASE` variable can be set to either of
the two.

- $(AUTORELEASE):

Release is automagically set to the number of commits since the last
commit containing either ": update to " or ": bump to ".

Example below:

    $ git log packages/foobar/
    foobar: fixup file location
    foobar: disable docs
    foobar: bump to 5.3.2
    foobar: fixup copyright

Resulting package name: foobar_5.3.2-3_all.ipk, two package changes
since the last upstream version change, using a 1 based counter.

- $(COMMITCOUNT):

For non-traditional versioning (x.y.z), most prominent `base-files`,
this variable contains the total number of package commits.

The new functionality can also be used by other feeds like packages.git.

In case no build information is available, e.g. when using release
tarballs, the SOURCE_DATE_EPOCH is used to have a reproducible release
identifier.

README.md

OpenWrt logo

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

Development

To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

gcc binutils bzip2 flex python3 perl make find grep diff unzip gawk getopt
subversion libz-dev libc-dev rsync

Quickstart

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

  4. Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

Related Repositories

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.
