# Note [slotting support]
|
|
# -----------------------
|
|
# Gentoo's layout for binutils files is non-standard as Gentoo
|
|
# supports slotted installation for binutils. Many tools
|
|
# still expect binutils to reside in known locations.
|
|
# binutils-config package restores symlinks into known locations,
|
|
# like:
|
|
# /usr/bin/${CTARGET}-<tool>
|
|
# /usr/bin/${CHOST}/${CTARGET}/lib/ldscrips
|
|
# /usr/include/
|
|
#
|
|
# Note [tooldir hack for ldscripts]
|
|
# ---------------------------------
|
|
# Build system does not allow ./configure to tweak every location
|
|
# we need for slotting binutils hence all the shuffling in
|
|
# src_install(). This note is about SCRIPTDIR define handling.
|
|
#
|
|
# SCRIPTDIR defines 'ldscripts/' directory location. SCRIPTDIR value
|
|
# is set at build-time in ld/Makefile.am as: 'scriptdir = $(tooldir)/lib'
|
|
# and hardcoded as -DSCRIPTDIR='"$(scriptdir)"' at compile time.
|
|
# Thus we can't just move files around after compilation finished.
|
|
#
|
|
# Our goal is the following:
|
|
# - at build-time set scriptdir to point to symlinked location:
|
|
# ${TOOLPATH}: /usr/${CHOST} (or /usr/${CHOST}/${CTARGET} for cross-case)
|
|
# - at install-time set scriptdir to point to slotted location:
|
|
# ${LIBPATH}: /usr/$(get_libdir)/binutils/${CTARGET}/${PV}
|
