271# A list of headers to wrap for multilib support. The listed headers
272# will be moved to a non-standard location and replaced with a file
273# including them conditionally to current ABI.
274#
275# This variable has to be a bash array. Paths shall be relative to
276# installation root (${ED}), and name regular files. Recursive wrapping
277# is not supported.
278#
279# Please note that header wrapping is *discouraged*. It is preferred to
280# install all headers in a subdirectory of libdir and use pkg-config to
281# locate the headers. Some C preprocessors will not work with wrapped
282# headers.
283#
284# Example:
285# @CODE
286# MULTILIB_WRAPPED_HEADERS=(
287# /usr/include/foobar/config.h
288# )
289# @CODE

291# @ECLASS-VARIABLE: MULTILIB_CHOST_TOOLS

293# A list of tool executables to preserve for each multilib ABI.
294# The listed executables will be renamed to ${CHOST}-${basename},
295# and the native variant will be symlinked to the generic name.
296#
297# This variable has to be a bash array. Paths shall be relative to
298# installation root (${ED}), and name regular files or symbolic
299# links to regular files. Recursive wrapping is not supported.
300#
301# If symbolic link is passed, both symlink path and symlink target
302# will be changed. As a result, the symlink target is expected
303# to be wrapped as well (either by listing in MULTILIB_CHOST_TOOLS
304# or externally).
305#
306# Please note that tool wrapping is *discouraged*. It is preferred to
307# install pkg-config files for each ABI, and require reverse
308# dependencies to use that.
309#
310# Packages that search for tools properly (e.g. using AC_PATH_TOOL
311# macro) will find the wrapper executables automatically. Other packages
312# will need explicit override of tool paths.
313#

315# @CODE
316# MULTILIB_CHOST_TOOLS=(
317# /usr/bin/foo-config
