Description Diego Elio Pettenò (RETIRED) gentoo-dev 2011-06-01 21:40:32 UTC
== build log ==
checking for -z relro option... no
configure: error: linker with -z relro support required

== config.log ==
configure:6216: checking for -z relro option
configure:6223: i686-pc-linux-gnu-gcc  -v --help 2>&1|grep z relro 1>&5
configure:6226: $? = 1
configure:6240: result: no
configure:6243: error: linker with -z relro support required

Of course it wouldn't find it that way :|
Comment 1 SpanKY gentoo-dev 2011-06-02 17:12:03 UTC
that's the same exact test glibc has always used, and it works fine for everyone else.  re-open once you've posted some actual information.
Comment 2 Diego Elio Pettenò (RETIRED) gentoo-dev 2011-06-02 18:20:30 UTC
Okay GCC 4.6 does not report the linker's parameters in the --help output

Comment 3 SpanKY gentoo-dev 2011-06-03 04:44:37 UTC
yes, it does.  if it didnt, a lot of people would have complained by now.

$ gcc --version | head -1
gcc (Gentoo 4.6.0 p1.2, pie-0.4.5) 4.6.0

$ gcc -v --help |& grep -c 'z relro'

Comment 4 Diego Elio Pettenò (RETIRED) gentoo-dev 2011-06-05 16:28:57 UTC
gcc-4.6.0: error: unrecognized option ‘--version’
gcc-4.6.0 (Gentoo 4.6.0 p1.1, pie-0.4.5) 4.6.0

Looks like somebody bumped a patchset and not the rev for it?
Comment 5 Diego Elio Pettenò (RETIRED) gentoo-dev 2011-06-05 16:31:53 UTC
Not complaining about the missing revbump, let it be clear.

Just stating that it might be the problem here, waiting for a rebuild to see what happens.
Comment 6 Diego Elio Pettenò (RETIRED) gentoo-dev 2011-06-05 17:16:20 UTC
I know the problem now and that's _quite_ a bothersome one. If GCC_SPECS is set, I get the errors everywhere. If it isn't, everything's fine.
