support/scripts/eclipse-register-toolchain

   1 #!/bin/sh
   2
   3 # This script registers the toolchain of a Buildroot project into the
   4 # Eclipse plugin. To do so, it adds a new line for the Buildroot
   5 # toolchain into the $HOME/.buildroot-eclipse.toolchains file, which
   6 # the Eclipse Buildroot plugin reads to discover automatically the
   7 # available Buildroot toolchains on the system.
   8 #
   9 # This script should typically not be called manually. Instead, one
  10 # should enable the BR2_ECLIPSE_REGISTER configuration option, which
  11 # will lead Buildroot to automatically call this script with the
  12 # appropriate arguments.
  13 #
  14 # Usage:
  15 #  eclipse-register-toolchain project-directory toolchain-prefix architecture
  16 #
  17 #   project-directory is the absolute path to the Buildroot project
  18 #   output directory (which contains the host/, target/, build/,
  19 #   images/, etc. subdirectories). It should be an absolute and
  20 #   canonical path.
  21 #
  22 #   toolchain-prefix is the prefix of the cross-compilation tools, i.e
  23 #   'arm-linux-' if the cross-compiler executable is 'arm-linux-gcc'.
  24 #
  25 #   architecture is the lower-cased name of the architecture targetted
  26 #   by the Buildroot project.
