             Bug #: 56752
           Summary: GCC fails to bootstrap on Debian GNU/Linux 7.0
                    (wheezy) when x32 libraries aren't installed
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org

Last lines of compilation

I ran CC=gcc-4.6 ../gcc-4.8.0/configure
--prefix=/home/prosfilaes/bin/gcc-4.8.0/
--enable-languages=ada,c,c++,java,fortran
and then
make bootstrap
It fails with

(fuller log attached)
Poking at it, this seems to be telling me that I don't have a 32-bit
development package installed, which is true, but shouldn't it stop at
configure and tell me that instead of erring out in the middle of compilation
with an unhelpful error message?

No, that's the way it always has been.

I don't understand how "that's the way it always has been" is an answer. If
there's a library missing (especially one the installation instructions don't
mention), it should tell you that, not fail in the middle with an obscure error
message. That it has done in it in the past doesn't justify the behavior.

How do you propose to check that?

You might not have a 32-bit compiler with which to test those headers during
configuration, so it's not easy to test them until after we've bootstrapped a
multilib compiler.

Also this is nothing to do with x32, which is a different ABI, you just mean
32-bit.

Confirming as a dcoumentation bug,
http://gcc.gnu.org/install/specific.html#x86-64-x-x could mention that building
a bi-arch compiler requires both 32-bit and 64-bit libc

You could check that right after building the multilib compiler before trying
to compile real code. That would at least give an error message that said what
was wrong, instead of one that's opaque to the causal installer.
