# This script registers the toolchain of a Buildroot project into the
|
# Eclipse plugin. To do so, it adds a new line for the Buildroot
|
# toolchain into the $HOME/.buildroot-eclipse.toolchains file, which
|
# the Eclipse Buildroot plugin reads to discover automatically the
|
# available Buildroot toolchains on the system.
|
#
|
# This script should typically not be called manually. Instead, one
|
# should enable the BR2_ECLIPSE_REGISTER configuration option, which
|
# will lead Buildroot to automatically call this script with the
|
# appropriate arguments.
|
#
|
# Usage:
|
# eclipse-register-toolchain project-directory toolchain-prefix architecture
|
#
|
# project-directory is the absolute path to the Buildroot project
|
# output directory (which contains the host/, target/, build/,
|
# images/, etc. subdirectories). It should be an absolute and
|
# canonical path.
|
#
|
# toolchain-prefix is the prefix of the cross-compilation tools, i.e
|
# 'arm-linux-' if the cross-compiler executable is 'arm-linux-gcc'.
|
#
|
# architecture is the lower-cased name of the architecture targetted
|
# by the Buildroot project.
