Re: [gentoo-alt] Bootstrap: gcc failed

[yegle]

Here's more information about the system.

DSM 6.0 is a Debian based 64bit system. The company behind it haven't
released the toolchain for 6.0 version yet but I have a working toolchain
for DSM 5.2 which should be fine to bootstrap a prefix I assume.

I believe this is not a static only system since the binary (bash, ls,
etc.) are all dynamically linked. Here's the result from file (there's no
file command in system so I copied the binary to another server to get this
result): bash: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.32, stripped

/lib/libc.a is not included in the system, I created a symlink to the one
in the toolchain because when building gcc it complained that libc.a cannot
be found.

So far I have tried the following steps:

1. Run bootstrap-prefix.sh, stage2 failed with:

/volume1/gentoo/tmp/usr/x86_64-pc-linux-gnu/bin/ld: cannot find crti.o: No
such file or directory
/volume1/gentoo/tmp/usr/x86_64-pc-linux-gnu/bin/ld: cannot find -lc
/volume1/gentoo/tmp/usr/x86_64-pc-linux-gnu/bin/ld: cannot find crtn.o: No
such file or directory
collect2: error: ld returned 1 exit status
make[2]: *** [libgcc_s.so] Error 1
make[2]: Leaving directory
`/volume1/gentoo/tmp/var/tmp/portage/sys-devel/gcc-4.8.4/work/build/x86_64-pc-linux-gnu/libgcc'
make[1]: *** [all-target-libgcc] Error 2
make[1]: Leaving directory
`/volume1/gentoo/tmp/var/tmp/portage/sys-devel/gcc-4.8.4/work/build'
make: *** [all] Error 2

2. Modify $EPREFIX/tmp/etc/portage/make.conf and use
LDFLAGS="-L$TOOLCHAIN/usr/local/x86_64-pc-linux-gnu/x86_64-pc-linux-gnu/sys-root/usr/lib"
where crti.o/crtn.o located, but same error as step 1.

3. Noticed ld's default search directory, I created symlink to
$TOOLCHAIN/usr/local/x86_64-pc-linux-gnu/x86_64-pc-linux-gnu/sys-root/usr/lib
at $EPREFIX/tmp/usr/x86_64-pc-linux-gnu/lib64

$ /volume1/gentoo/tmp/usr/x86_64-pc-linux-gnu/bin/ld --verbose|grep SEARCH
SEARCH_DIR("/volume1/gentoo/tmp/usr/x86_64-pc-linux-gnu/lib64");
SEARCH_DIR("/volume1/gentoo/tmp/usr/lib/binutils/x86_64-pc-linux-gnu/2.2464");
SEARCH_DIR("/usr/local/lib64"); SEARCH_DIR("/lib64");
SEARCH_DIR("/usr/lib64");
SEARCH_DIR("/volume1/gentoo/tmp/usr/x86_64-pc-linux-gnu/lib");
SEARCH_DIR("/volume1/gentoo/tmp/usr/lib/binutils/x86_64-pc-linux-gnu/2.24");
SEARCH_DIR("/usr/local/lib"); SEARCH_DIR("/lib"); SEARCH_DIR("/usr/lib");

But still some error:
/volume1/gentoo/tmp/usr/x86_64-pc-linux-gnu/bin/ld: cannot find crti.o: No
such file or directory
/volume1/gentoo/tmp/usr/x86_64-pc-linux-gnu/bin/ld: cannot find
/usr/lib64/libc_nonshared.a
collect2: error: ld returned 1 exit status
make[2]: *** [libgcc_s.so] Error 1
make[2]: Leaving directory
`/volume1/gentoo/tmp/var/tmp/portage/sys-devel/gcc-4.8.4/work/build/x86_64-pc-linux-gnu/libgcc'
make[1]: *** [all-target-libgcc] Error 2
make[1]: Leaving directory
`/volume1/gentoo/tmp/var/tmp/portage/sys-devel/gcc-4.8.4/work/build'
make: *** [all] Error 2

So I'm here now, completely clueless...
