[Clfs-support] Current Patches and Updates

[Martin Ward]

Here is my current build  run through

I only do pure 64, but the specs patch should be good for a multi-lib build

Cross Compile tools

Built from Built from 32 bit CLFS kernel 2.6.38.3, glibc 2.14, gcc 4.6.1

Very similar to current dev versipon

I use porg to log my build, the current version cross compiles nicely

5.2 File updated to 5.29

5.3 kernel headers update to latest kernel currently 4.9.3

5.4 M4 updated to 1..4.18

5.5  Ncurses update to latest patch level can provide patch if needed

5.6 Pkg-config lite, don't use , prefer pkg-conf, version 1.1.1 currently

./configure --prefix=/cross-tools 
--with-pkg-config-dir=/tools/lib/pkgconfig:/tools/share/pkgconfig
ln -sv /cross-tools/bin/pkgconf /cross-tools/bin/pkg-config

5.7 gmp updated to 6.1.2

5.8 mpfr updated to 3.1.5 patch level 5

5.9 mpc  no change

5.10 isl updated 0.18

5.11 cross binutils updated to 2.27 (2.28 is imminent)

removed with gold as build toolchain is to old and really can't see why 
we need it anyway at this stage

added --with-system-zlib

5.12  cross gcc static, updated to 6.3.0 (specs patch attached, it was 
for 6.1 but still works for 6.x versions, should be multi lib ok)

my build command

AR=ar LDFLAGS="-Wl,-rpath,/cross-tools/lib"    ../gcc-6.3.0/configure 
--prefix=/cross-tools --build=${CLFS_HOST} --host=${CLFS_HOST} 
--target=${CLFS_TARGET} --with-sysroot=${CLFS} 
--with-local-prefix=/tools 
--with-native-system-header-dir=/tools/include --disable-nls 
--disable-shared --with-gmp=/cross-tools --with-mpfr=/cross-tools 
--with-mpc=/cross-tools --without-headers --with-newlib 
--disable-decimal-float --disable-libgomp --disable-libssp 
--disable-threads --disable-multilib --disable-libatomic 
--disable-libitm --disable-libsanitizer  --disable-libquadmath 
--disable-libvtv --disable-libcilkrts --disable-libstdc++-v3 
--disable-libmpx --disable-target-libiberty --disable-target-zlib 
--with-system-zlib --enable-languages=c --enable-checking=release 
--disable-werror --with-glibc-version=2.24

5.13 glibc

updated to 2.24, and set kernel to a later version(3.7)

removed --enable-obsolete-rpc , not needed at this stage

5.14 final cross gcc

my build command

AR=ar LDFLAGS="-Wl,-rpath,/cross-tools/lib" ../gcc-6.3.0/configure 
--prefix=/cross-tools --build=${CLFS_HOST} --target=${CLFS_TARGET} 
--host=${CLFS_HOST} --with-sysroot=${CLFS} --with-local-prefix=/tools 
--with-native-system-header-dir=/tools/include --disable-nls 
--disable-static --enable-languages=c,c++ --enable-__cxa_atexit 
--enable-threads=posix --disable-multilib --with-gmp=/cross-tools 
--with-mpc=/cross-tools --with-mpfr=/cross-tools --with-isl=/cross-tools 
--with-system-zlib --enable-checking=release --enable-libstdcxx-time 
--disable-werror


Further updates for the tools environment later

i would update tickets, but they never seem to get closed, these days
