configure error: linker with -z relro support required

[Jeff Liu]

Dear Developer,

I just tried to run `configure' against glibc git version, but it failed
with the following issue:

***@pibroch:~/gnu$ ./glibc/configure
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking for gcc... gcc
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
..........
.....
checking for .preinit_array/.init_array/.fini_array support... yes
checking whether to use .ctors/.dtors header and trailer... mawk: line

yes
checking for libunwind-support in compiler... no
checking for -z nodelete option... yes
checking for -z nodlopen option... yes
checking for -z initfirst option... yes
checking for -z relro option... no
configure: error: linker with -z relro support required

Actually, the `ld' in my binutils is definitely support this feature:
***@pibroch:~/gnu$ `which ld` --help|grep relro
-z norelro Don't create RELRO program header
-z relro Create RELRO program header
-z norelro Don't create RELRO program header
-z relro Create RELRO program header
-z norelro Don't create RELRO program header
-z relro Create RELRO program header

Any hint?

Thanks,
-Jeff

configure: error: linker with -z relro support required

See config.log. What ld are you using?

Hi Jonathan,

Thanks for your prompt response!

See config.log. What ld are you using?

looks it does not specified the absolute path for `ld', in this case,
IMHO, it means the '/usr/bin/ld'.

looks it does not specified the absolute path for `ld', in this case, IMHO,
it means the '/usr/bin/ld'.

I was referring to which _implementation_ of ld you use. It should be
possible to find out by running "ld --version" and seeing if it
mentions "GNU Binutils" or "gold". (The latter is not supported for
building eglibc yet iirc, though Roland was working on it.)

Ah, then it's Roland's fault.

Commit 9fa2c032 ("Adjust relro test to work around GNU ld limitations.")
might help. Sorry for the nonsense before --- I'm behind the times. :)

Its very nice of you to point me out that, I'll try until find out a
workable commit.

Any hint?

Use gawk. Unless things have been fixed in the last 10 years glibc's
configure didn't work with mawk. YMMV.

Cheers,
Carlos.

Thanks for pointing this out, after replacing to gawk, everything is
fine. :)

Oops!

unlucky, although configure procedure works fine for me, but make still
failed due to the following issue:

Yes, this is the now classic i686 compiler define problem.

You need patches similar to this:
http://sourceware.org/ml/libc-alpha/2006-04/msg00090.html

Or stop using --with-arch.

Cheers,
Carlos.

Use gawk instead of mawk.

sudo apt-get install gawk
Works for me.
