298# @DESCRIPTION:
299# A list of headers to wrap for multilib support. The listed headers
300# will be moved to a non-standard location and replaced with a file
301# including them conditionally to current ABI.
302#
303# This variable has to be a bash array. Paths shall be relative to
304# installation root (${ED}), and name regular files. Recursive wrapping
305# is not supported.
306#
307# Please note that header wrapping is *discouraged*. It is preferred to
308# install all headers in a subdirectory of libdir and use pkg-config to
309# locate the headers. Some C preprocessors will not work with wrapped
310# headers.
311#
312# Example:
313# @CODE
314# MULTILIB_WRAPPED_HEADERS=(
315# /usr/include/foobar/config.h
316# )
317# @CODE
318
319# @ECLASS-VARIABLE: MULTILIB_CHOST_TOOLS
320# @DESCRIPTION:
321# A list of tool executables to preserve for each multilib ABI.
322# The listed executables will be renamed to ${CHOST}-${basename},
323# and the native variant will be symlinked to the generic name.
324#
325# This variable has to be a bash array. Paths shall be relative to
326# installation root (${ED}), and name regular files or symbolic
327# links to regular files. Recursive wrapping is not supported.
328#
329# If symbolic link is passed, both symlink path and symlink target
330# will be changed. As a result, the symlink target is expected
331# to be wrapped as well (either by listing in MULTILIB_CHOST_TOOLS
332# or externally).
333#
334# Please note that tool wrapping is *discouraged*. It is preferred to
335# install pkg-config files for each ABI, and require reverse
336# dependencies to use that.
337#
338# Packages that search for tools properly (e.g. using AC_PATH_TOOL
339# macro) will find the wrapper executables automatically. Other packages
340# will need explicit override of tool paths.
341#
342# Example:
343# @CODE
344# MULTILIB_CHOST_TOOLS=(
345# /usr/bin/foo-config
346# )

361# between the successive calls to multilib_prepare_wrappers
