# Sysroot based SANE multilib cross-compiler build for LFS style builds
# Ryan Oliver - 20081219
#==============================================================================
# Yes, toolchain is basically cross-lfs minus the cross-gcc-final, and we
# are natively building the target-native toolchain (after booting
# an appropriate x86_64 kernel) as opposed to performing
# the canadian cross in cross-lfs.
#
# Added --with-sysroot option so we can use native specs/config options
# when cross-compiling (cross toolchain looks under $LFS/tools as opposed to
# just /tools for headers and libs after standard toolchain mods)
#
# This frees us from being tied to STARTFILE_PREFIX_SPEC as the sole
# available mechanism for adjusting startfile search path when cross.
#
# We now adjust STANDARD_STARTFILE_PREFIX_{1,2}
# directly in the driver to set the standard library/startfile search path.
#
# These do not show up in specs, so specs appear
# exactly as intended by gcc (well, apart from our dynamic linker mod)
#------------------------------------------------------------------------------
# Also, this build here is using a combined gcc + binutils tree.
# Will provide another doc for a standard build (basically use cross-lfs and
# perform the relevant gcc/binutils mods described in this doc)
#------------------------------------------------------------------------------
# OK, for me BUILD_HOST today is i686-pc-linux-gnu (Old 2.4 based RH box)
#
# To ensure though that BUILD_HOST does not equal target throughout
# I am fudging it to be i686-build-linux-gnu
#
# This is primarily so glibc does not assume we are native compiling...
# Things get unhappy if you are building on a 2.4 kernel otherwise ;)
#
# We could just as easily fudge the targets to be x86_64-clfs-linux-gnu or
# i686-clfs-linux-gnu
#
# Change to however you want it to be
BUILD_HOST=i686-build-linux-gnu
mkdir ${LFS}/tools
ln -sf ${LFS}/tools /
# Tools linked against the host dont have to live under $LFS
# they can live anywhere (in your home directory for example)
#
# Here we just follow clfs.
#
# This keeps all our binaries/libs compiled and linked against
# the host outside of /tools
#
# It also means that the cross toolchain never gets clobbered making
# it very easy to restart a build
# ( ie: blow away /tools, re-install linux headers, continue at glibc )

# Sysrooted toolchain build
# OK this is probably too much, but I wanted to use binutils 2.19
# and use a combined gcc + binutils build tree for some giggles.
#
# The zlib dependency is not an issue when using the hosts zlib,
# (the whole toolchain is linked against the host ).
#
# Haven't really checked if the zlib dependency is satisfied by the
# zlib in the gcc tree...
#
# Easy enough to break the build back into separate binutils and gcc,
# just split the options into the appropriate build
#
# For the book I probably wouldn't recommend the combined tree, because
# no-one ever sticks to the prescribed versions ;)

# The following patch makes genscripts process LIB_PATH
# (--with-libpath option) to provide
