|
# This is not for you unless you are using a pre-built OpenWRT toolchain
|
|
# This is a productivity script that should be sourced from a Bash shell
|
|
#
|
|
# It is meant to be used after unpacking pre-built OpenWrt toolchains, which
|
|
# are named like this:
|
|
#
|
|
# OpenWrt-Toolchain-xxx-yyy-5.3.0_musl-1.1.16.Linux-x86_64.tar.bz2
|
|
#
|
|
# A huge collection of them can be found at the following location:
|
|
#
|
|
# https://downloads.openwrt.org/snapshots/trunk/
|
|
#
|
|
# This file should be placed in /path/to/installed/toolchain/
|
|
# The file must be in the root directory of the subdirectory of the unpacked
|
|
# toolchain - NOT the directory that contains the LICENSE file, but the main
|
|
# directory under that
|
|
#
|
|
# You can name the script whatever you want, I prefer to call it 'activate'
|
|
# All you need to do is source it (from any working directory) and it will set
|
|
# your environment up for building software via build systems like configure
|
|
# as well as for manual invocation via gcc, ld, etc. It helps with static
|
|
# linking by setting some static library locations as environment variables
|
|
# as well
|
|
#
|
|
# Assumptions are made, YMMV. It works well for me when I work on weird stuff
|
