Sorry to be a pain on this one...
I think I did those things all right, but the hardened-specs.sh
wasn't changing the specs, and I did have issues. It's
small, so I wiped it. After a couple of tries here I convinced
myself I have a problem, with an error repeating over 2 builds.
So I wiped, and went over this slowly, logging as I went.
Linux-libc-headers: pseudo_random patch
uclibc headers: config-1 patch
binutils cross: uClibc_conf-1 patch, make etc, remake ld
gcc cross compiler uClibc_conf-1, sed, specs_x86-1, echo &
touch, etc.
uClibc arc4random-2, config-1, libc_stack_end-1
patches, install locales, 7 sed commands to
rules.mak & .config, make, rm includes, install
Adjusting the toolchain: Requesting program interpreter:
/tools/lib/ld-uClibc.so.0
binutils (2) uClibc_conf-1, pt_pax-1 patches, env..configure,
etc., remake ld.
gcc (2) uClibc_conf-1, uClibc_libstdc++-1, uClibc_locale-1
patches, sed, ssp-1 patch, another sed, specs_x86-1,
no_fixincludes-1 patches, mkdir & cd, env..configure,
make, install, link cc, install script, harden specs.
write test.c. This fails to compile as follows:
hlfs:/mnt/hlfs/sources/gcc-build$ gcc -o test test.c
/mnt/hlfs/tools/bin/../lib/gcc/i686-tools-linux-uclibc/3.4.4/../../../../i686-tools-linux-uclibc/bin/ld:
unrecognized option '-p'
/mnt/hlfs/tools/bin/../lib/gcc/i686-tools-linux-uclibc/3.4.4/../../../../i686-tools-linux-uclibc/bin/ld:
use the --help option for usage information
collect2: ld returned 1 exit status
I also took a copy of $(gcc --print-file specs) before & after the
hardened-specs script was run, and
they are different (3917 and 4312 bytes resp.). I seem to be
linking against /tools
hlfs:/mnt/hlfs/sources/gcc-build$ ldd /tools/bin/cc
libc.so.0 => /tools/lib/libc.so.0 (0xb7f04000)
ld-uClibc.so.0 => /tools/lib/ld-uClibc.so.0 (0xb7f9c000)
ld doesn't have a -p option. No CFLAGS or LDFLAGS are set. I
initially suspected perl, but it runs spamassassin with no errors
here and did alter the specs.
