The feeds script sets value of TOPDIR in a way that is inconsistent
with how toplevel Makefile sets it. The inconsistency manifests when I
use a "build directory" with symlinks to LEDE source (see below).
When make is invoked in such a directory, make's TOPDIR variable is
set to that directory, whereas scripts/feeds sets TOPDIR to the top of
LEDE source, which results in creating feeds directory inside the LEDE
source instead of in the build directory.
This patch changes the script so that it reuses the TOPDIR value form
the environment if it exists. The result is that 'make
package/symlinks' correctly fetches feeds to the build directory
instead in the source.
I use the following commands to create the build directory:
ln -s $SRC/config config
ln -s $SRC/Config.in Config.in
ln -s $SRC/feeds.conf.default feeds.conf.default
ln -s $SRC/include include
ln -s $SRC/Makefile Makefile
mkdir package
ln -s $SRC/package/base-files package/base-files
ln -s $SRC/package/boot package/boot
ln -s $SRC/package/devel package/devel
ln -s $SRC/package/firmware package/firmware
ln -s $SRC/package/kernel package/kernel
ln -s $SRC/package/libs package/libs
ln -s $SRC/package/Makefile package/Makefile
ln -s $SRC/package/network package/network
ln -s $SRC/package/system package/system
ln -s $SRC/package/utils package/utils
ln -s $SRC/rules.mk rules.mk
ln -s $SRC/scripts scripts
ln -s $SRC/target target
ln -s $SRC/toolchain toolchain
ln -s $SRC/tools tools
This allows me to easily test changes in LEDE on multiple targets.

This is the buildsystem for the LEDE Linux distribution. Please use "make menuconfig" to choose your preferred configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your LEDE Community http://www.lede-project.org
