293# @DESCRIPTION:
294# A list of headers to wrap for multilib support. The listed headers
295# will be moved to a non-standard location and replaced with a file
296# including them conditionally to current ABI.
297#
298# This variable has to be a bash array. Paths shall be relative to
299# installation root (${ED}), and name regular files. Recursive wrapping
300# is not supported.
301#
302# Please note that header wrapping is *discouraged*. It is preferred to
303# install all headers in a subdirectory of libdir and use pkg-config to
304# locate the headers. Some C preprocessors will not work with wrapped
305# headers.
306#
307# Example:
308# @CODE
309# MULTILIB_WRAPPED_HEADERS=(
310# /usr/include/foobar/config.h
311# )
312# @CODE
313
314# @ECLASS-VARIABLE: MULTILIB_CHOST_TOOLS

316# A list of tool executables to preserve for each multilib ABI.
317# The listed executables will be renamed to ${CHOST}-${basename},
318# and the native variant will be symlinked to the generic name.
319#
320# This variable has to be a bash array. Paths shall be relative to
321# installation root (${ED}), and name regular files or symbolic
322# links to regular files. Recursive wrapping is not supported.
323#
324# If symbolic link is passed, both symlink path and symlink target
325# will be changed. As a result, the symlink target is expected
326# to be wrapped as well (either by listing in MULTILIB_CHOST_TOOLS
327# or externally).
328#
329# Please note that tool wrapping is *discouraged*. It is preferred to
330# install pkg-config files for each ABI, and require reverse
331# dependencies to use that.
332#
333# Packages that search for tools properly (e.g. using AC_PATH_TOOL
334# macro) will find the wrapper executables automatically. Other packages
335# will need explicit override of tool paths.

339# MULTILIB_CHOST_TOOLS=(
340# /usr/bin/foo-config
