[Buildroot] [PATCH 2/5] toolchain: rename external toolchain dir

Yann E. MORIN yann.morin.1998 at anciens.enib.fr
Tue Jun 1 21:53:00 UTC 2010


Rename the external toolchain directory.
When new backends are here, it will be easier to sort them out
if they are all prefixed the same way.

-# This file implements the support for external toolchains, i.e
-# toolchains that have not been produced by Buildroot itself and that
-# are already available on the system on which Buildroot runs. So far,
-# we have tested this with:
-#
-#  * Toolchains generated by Crosstool-NG
-#  * Toolchains generated by Buildroot
-#  * ARM toolchains made available by Codesourcery
-#
-# The basic principle is the following
-#
-#  1. Perform some checks on the conformity between the toolchain
-#  configuration described in the Buildroot menuconfig system, and the
-#  real configuration of the external toolchain. This is for example
-#  important to make sure that the Buildroot configuration system
-#  knows whether the toolchain supports RPC, IPv6, locales, large
-#  files, etc. Unfortunately, these things cannot be detected
-#  automatically, since the value of these options (such as
-#  BR2_INET_RPC) are needed at configuration time because these
-#  options are used as dependencies for other options. And at
-#  configuration time, we are not able to retrieve the external
-#  toolchain configuration.
-#
-#  2. Copy the libraries needed at runtime to the target directory,
-#  $(TARGET_DIR). Obviously, things such as the C library, the dynamic
-#  loader and a few other utility libraries are needed if dynamic
-#  applications are to be executed on the target system.
-#
-#  3. Copy the libraries and headers to the staging directory. This
-#  will allow all further calls to gcc to be made using --sysroot
-#  $(STAGING_DIR), which greatly simplifies the compilation of the
-#  packages when using external toolchains. So in the end, only the
-#  cross-compiler binaries remains external, all libraries and headers
-#  are imported into the Buildroot tree.
