In the package guidelines, PKG_VERSION is supposed to be used as "The upstream version number that we're downloading", while PKG_RELEASE is referred to as "The version of this package Makefile". Thus, the variables in a strict interpretation provide a clear distinction between "their" (upstream) version in PKG_VERSION and "our" (local OpenWrt trunk) version in PKG_RELEASE. For local (OpenWrt-only) packages, this implies that those will only need PKG_RELEASE defined, while PKG_VERSION does not apply following a strict interpretation. While the majority of "our" packages actually follow that scheme, there are also some that mix both variables or have one of them defined but keep them at "1". This is misleading and confusing, which can be observed by the fact that there typically either one of the variables is never bumped or the choice of the variable to increase depends on the person doing the change. Consequently, this patch aims at clarifying the situation by consistently using only PKG_RELEASE for "our" packages. To achieve that, PKG_VERSION is removed there, bumping PKG_RELEASE where necessary to ensure the resulting package version string is bigger than before. During adjustment, one has to make sure that the new resulting composite package version will not be considered "older" than the previous one. A useful tool for evaluating that is 'opkg compare-versions'. In principle, there are the following cases: 1. Sole PKG_VERSION replaced by sole PKG_RELEASE: In this case, the resulting version string does not change, it's just the value of the variable put in the file. Consequently, we do not bump the number in these cases so nobody is tempted to install the same package again. 2. PKG_VERSION and PKG_RELEASE replaced by sole PKG_RELEASE: In this case, the resulting version string has been "version-release", e.g. 1-3 or 1.0-3. For this case, the new PKG_RELEASE will just need to be higher than the previous PKG_VERSION. For the cases where PKG_VERSION has always sticked to "1", and PKG_RELEASE has been incremented, we take the most recent value of PKG_RELEASE. Apart from that, a few packages appear to have developed their own complex versioning scheme, e.g. using x.y.z number for PKG_VERSION _and_ a PKG_RELEASE (qos-scripts) or using dates for PKG_VERSION (adb-enablemodem, wwan). I didn't touch these few in this patch.

-----------------------------------------------------
This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
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 Linux kernel & all
chosen applications for your target system.
Sunshine!
