Many tools # still expect binutils to reside in known locations. # binutils-config package restores symlinks into known locations, # like: # /usr/bin/${CTARGET}- # /usr/bin/${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}
